4. Original NTN terms such as “air blow during driving” is used. Please inquire of NTN for details of the operation.

3．Function and Features(1) High precision digital control with micro processor
As various settings and operations are controlled digitally, highly precise and highly stabilized control is achieved. At
the same time, as a set value is displayed digitally, resetting of values is easy.
(2) Wide input “responding to wide voltage of power supply”
The input voltage ranges widely as AC100-115/200-230V±10% (50/60Hz ±10%). The output voltage automaticallychanges to 100V output or 200V output according to the power-supply voltage. When the AC200V output isnecessary for the AC100V input, please change to the type equipped with AC100V power source unit K-UE083.
(3) Installation of Constant amplitude function (Refer to P.28)
Constant amplitude function is installed to control output voltage so as to feedback signals from sensor and to makeamplitude of parts feeder constant.
(4) Installation of Resonance point tracking function (Refer to P. 31)
Resonance point tracking function to feedback drive frequency so as to operate always at resonance point is installed.
When resonance point tracking is selected, constant amplitude function is also ON automatically.
(5) Multi-speed function (Refer to P.20, Function H11 to 20 in P.40, and P.50)
Three kinds of speed data can be memorized internally, and the speed can be changed by the switch signal from theoutside. Moreover, non-step (1V or 1% unit) speed control of the output voltage by the analog voltage is possible.
(6) Enhancement of the protection function
Various kinds of protection function enhancing output short-circuit, overload etc. are installed as standard equipment.
Moreover, outputting of signals according to protection operation is possible.
(7) Panel lock (Refer to P.49）

Note 1. The controller for the parts feeder must be connected to the power supply of the commercial power or the sine
wave voltage output. Please do not connect it to the output side of the inverter that contains the harmoniccomponent such as sine wave PWM inverters. The controller breaks down.
Note 2. Please set up a leak detector or a leak breaker on the controller primary side for the protection of the earth
faulty-accident. Refer to the paragraph of the specification in P.57 for the current rating.
Note 3. Power supply cable length shall be 10m or less. Moreover, please use the cable of the size of 2.5mm2 or morewhen extending it to 3m or more (The protection coordination with the primary side breaker is noted). Since it
is necessary to remove the cover on the left side when you connect the power supply cable, the engineer who
is familiar with controller's content shall do this operation. Additionally, the connection to the controller terminal
board must be done by using the round type crimping terminal (The terminal screw: M3).
Note 4. Please refer to "Notes for transformer usage" in the bottom column in the next page when you use thetransformer.
Note 5. Correct earth shall be checked by a protection continuity tester after the earth construction work ends. Whenthe earth is imperfect, it is likely to get an electric shock.
Note 6.There is a possibility that the noise is added in the power supply line. Please take measures such as separationof the power supply from equipments which dislike noise or insertion of noise filter. Moreover, please do not put
the main circuit (power supply or load line) and the signal line in the same duct (protection tube).
Note 7 It is possible to connect it to the three phase power supply. In this case, please use two phases (for example, R
and S phases) out of three phases (R, S and T) for the power supply. In addition, please wire after confirming

separately placed as wiring of level switch isnecessary.
*3 The connection to the controller terminal board must be
done by using the round type crimping terminal (Theterminal screw: M3).
*4 Calibration is not possible, unless the earth cable
is connected to the controller.
Note 1 Extension of cable length
Please use the size of 1.0mm2 or more when you change the cable. Moreover, when extending it to 3m or
more, please connect it to the main body cable by extending it to the vicinity of the main body by using thecable of the size of 2.5mm2 or more, and using the relay BOX.

Extension length shall be 10m or less.

Note 2 There is a possibility that the noise is added in the load cable. When the load cable is close to equipments
which dislike noise, please take measures such as separation of wiring route from them and the use of shield
cable. Moreover, please avoid to wire in parallel with the vibration sensor lead or to wire the load cable andthe signal line in the same duct (protection tube).
Note 3 Correct earth shall be checked by protection continuity test machine after the earth construction work ends.
When the earth is imperfect, it is likely to get an electric shock.

＊ Notes for transformer usage
Please note not only the current rating but also the voltage descent due to the inrush current, etc. when you supply
power to the controller through the transformer. Please note enough the voltage descent at power supply ON andthe trouble due to the noise especially when the transformer is set commonly with other equipments. Please
consult the transformer maker about details of the problem when supplying the power to the controller (inverter).
Please refer to the paragraph of the input in P.57 for controller's inrush current. Moreover, to reduce the influenceby the noise, the use of the shielded wire or wiring of a distance as short as possible is recommended.

①Installation of vibration sensor
Please install the attached sensor to the upper sectionof the vibration main body or the vibrating section of thebowl or the trough etc. referring to the figure below.
Please prepare processing of tapping holes (M3 tappingat two places, 10mm pitch) on the installation section andinstallation screws in your company. Moreover, pleaseinstall at the position where the impact is not easilytransmitted to the vibration sensor when work falls off on
the bowl or the chute.
②Installation direction of vibration sensor
As vibrating direction of the vibration sensor ispredetermined (Arrow mark printed on the sensor is aforwarding direction of work), please note the installation
direction. Please note that it is different from theconventional vibration sensor K-P1395. Unless the
direction to let vibrate is not matched, it does not work
accurately. When it is not possible to match the directionof arrow mark to the forwarding direction of work, pleaseinstall it in the reverse direction and reverse the polarity
with the function J07.
※ In particular, for the bowl of heavy inertia mass etc.,
there is rarely a case that making the vibration
direction reverse is better. When it can not be
adjusted well, please try to reverse the data of J07.
※For the bowl feeder such as G type, N type, K type, it
is recommended to installed on the upper vibrator. In
particular, the G type, N type has a cover, it works as
a protection for the vibration sensor.
※In case of the linear feeder, it is recommended
to fix to the chute fixing bench (trough).

③Wiring of vibration sensor
It is recommended that the lead of vibration sensor is fixed nearby the fixing screws for the vibration sensor
using a nylon saddle etc. Unless it is fixed, there is a possibility that vibration of the lead is picked up as noise.
Please pull the lead around separately from the load cable of the parts feeder. If they are wired inparallel, noise might be picked up. Moreover, the lead uses the shield cable. As the external coat of shield cable isweak against the external force, it is recommended to protect it with a external tube etc.
When the installation of the vibration sensor is completed, please plug the connector of the vibration sensor into
the controller.
Notes for extension of lead
Please use an exclusive extension cable (K-P1400: 3m long),

Cautionwhich is available as an option. It is possible to make it max.11m

Notes for extension using shield cable
Please use a one core shield cable or a coaxial cable for the shield cable and connect the shield side also to
the connector of the controller without fail. Do not connect to other OV or the earth.
Even in case that the shield cable is used, the length of extension should be 10m or less. However, as there
is a possibility that noise is transmitted depending on the environment even within 10m, please try to make itshorter if possible. (Reference: Recommended cable 1.5D-2V [Coaxial cable])Then, installation and wiring of the vibration sensor are completed. By the connection of the vibration sensor, theconstant amplitude control or the resonance point tracking control etc. becomes possible. But, in order to use thesefunctions, adjustment of functions etc. is needed furthermore. Please use referring to the driving/adjustment method in

the solenoid valve does not exceed the capacity (200mA) of

The configuration and the switching capacity of the drive circuitof P1 and P2 terminals are the same as those of the terminal P0(Refer to P.18).
Other notes for the connection are also the same as for theterminal P0.

When the solenoid valve is not connected, it is possible to use it as two rows AND overflow control in theparagraph 5 (1) below. In this case, although a logic reversing of each input becomes possible, because thetimer is added for each, it is necessary to set the time of timer for both 1 and 2 of ON/OFF Delay.
5. Other controls by sensor and solenoid valve
In addition to 1~4 explained above, the following controls are possible.
(1) To stop the parts feeder with the two rows AND overflow by using two sensors in case of discharging two
rows by the parts feeder. (In case that air is not used for the overflow control)(2) In case that one row is discharged on the chute, overflow sensor is fitted respectively to chute inlet andoutlet, then when the work exists, the sensor at the chute inlet turns the parts feeder OFF, and when thework does not exist, the sensor at the chute outlet turns the parts feeder ON.
(3) The overflow sensor on the chute outputs this sensor signal to the terminal P2 as well as controlling thenormal overflow (branching of signal).
(4) The overflow sensor controls the normal overflow and also outputs the jam signal to the terminal P2 when
the work is not detected for a certain time. It can be used for jam air blow control of NTN spring separate
feeder.
※ As for the air overflow control (NTN internal nominal designation) explained on P.18~19, the behavior becomes
rather complicated. When you are already well aware of the content, it is possible to cover the wide range control
by using these functions. Please contact NTN for the detail or obtain separately the control manual for confirmation.

(4) Driving/Adjustment【Selection of feedback mode at time of driving】①Kind of feedback modes at time of driving
Control operation at time of driving of ECG25 type (or ECJ45 type) controller can be selected.
Control operations of feedback are following three kinds.
(A) Constant voltage mode: This is a mode generally used (Initial setting at the time of shipment). It
controls the constant voltage so that the load (output) voltage becomes thevalue set by the speed adjustment knob.
(B) Constant amplitude mode: Select this mode when the weight variation of work is large or morestable feeding operation is required. Amplitude of parts feeder is madesteady by feeding back the vibration sensor signal.
(C) Resonance point tracking mode: Select this mode when more efficient driving is required. This
controls so that the amplitude becomes steady at the resonance point ofparts feeder by feeding back vibration sensor signal. In the resonancepoint tracking mode, the constant amplitude control also becomes ON at
the same time.
To drive by the constant amplitude mode or the resonance point tracking mode, implementation ofcalibration is necessary in advance. When the calibration ends, it automatically shifts to the driving
mode by the corresponding feed back.
②Selection method of feed back mode at time of driving
It is automatically selected when calibration of corresponding mode is done,. In case of manualchange, refer to description below. Before implementing calibration, please confirm that wiring of thevibration sensor ends. Moreover, when driving begins by selecting the resonance point tracking mode
without calibration, there is a possibility of stop due to frequency lost error (FE3). Be careful of it.
Frequency lost error (FE3) is an abnormality warning which is output in case that frequency data
memorized at time of calibration and frequency of actual driving are much different, and manual
resetting (refer to P.53) becomes necessary.
【Manual switching method of feed back mode】※ Before switching feedback manually, please confirm that controller is in the stopping state (in casethat the external control terminal is at stop side or panel control, press the STOP key). If it isdifficult to cut off the external control, please select the panel control [2[ with the driving method
selection [J02] before the following procedure③. Then the controller stops.

Content
To prevent the operational error, operations by other than a specified key
can be made unacceptable. The data of J00 can be changed only bypressing the stop key and UP or Down key at the same time for theoperational error prevention.
0：Do not lock
1：LockWhen locked, the data change of other than a specific function (J00 andJ10) is prohibited (The RUN/STOP key is effective when the panel
operation is specified). The access to the function data is possible though
the data cannot be changed.
When the data change operation is done during the operation lock, thecharacters of Loc are displayed with blinking. Moreover, when the lock isreleased when the knob lock (Refer to P.49) is set, the knob lock is also
released because the operation lock is given priority. Please set it again
when the knob lock is necessary.
The current rating of the connected main body of the vibration is set. So as
not to exceed this current value, the controller automatically adjusts the output
voltage of the load. The initial value is set to 2.00A (4.00A for ECJ45). If thisvalue is not set, the overload protection function doesn't operate normally.
Therefore set it for the parts feeder whose current rating is 0.2A (0.5A for
ECJ45) or more before driving. Possible set range is 0.10~2.50A (0.10~5.00A
for ECJ45) but the use range is 0.20~2.00A (0.50~4.50A for ECJ45). For theparts feeder of less than 0.2A (0.5A for ECJ45), the overload warning function
may not operate normally because it cannot measure the load current
accurately. For the parts feeder of less than 0.2A (0.5A for ECJ45), set to
0.2A (0.5A for ECJ45) to use in order not for the overload warning function tooperate. If setting at less than 0.20A (0.5A for ECJ45), it is necessary to set
correcting the error of instruction value by the electric power meter for
inverter.
For ECJ45, normal driving of only N40 half wave main body is possible evenat setting of 4.5A. Please limit the setting of exceeding 2.00A (4.50A for
ECJ45) only to the short-time operation such as for the adjustment. Driving for
more than 30 minutes exceeding 2.00A (4.50A for ECJ45) makes the life ofcontroller extremely shorter.

Note on limit of current rating
The maximum value to be able to set the output voltage is limited first by the F/V curve (Refer to P.51), and even
within the set range of the F/V curve, when it exceeds the set current, the controller automatically lowers the output
voltage to make load current within the set value (Driving continues). At this time, the output voltage and the OL
are alternately displayed (OL blinks). This condition means that the vibration is insufficient even main body of thevibration is in the state of full load. Please check whether no abnormality exists. The warning signal comes out in
AL1 while the OL is blinking (when the setting of J08 is 1, 2, 4 and 5).
Moreover, when the output voltage becomes 20V or less but load current does not drop less than the set value,
driving is stopped by an overload abnormality (OL lights). In this case, an emergency signal is output to theterminal EM. (Refer to P.52)

It is not possible to get the ON/OFF delay timer to work with the external
control terminal signal.
Even when the driving is stopping by the external control (J02 is 0 or 1), it ispossible to drive compulsorily only while the RUN button of the operation
panel is being pressed. Please use it at the initial supply of the work ordischarging or at the time of adjustment. The JOG lamp (green) on the side of
the RUN button lights when JOG drive can be done.

1：JOG (compulsory single) driving function is used.
Even if a knob lock or the operation lock is set, the JOG driving is effective.
The F/V curve is set according to the main body used.
Data can be changed only while driving is stopping. Please surely confirm thesetting before driving. When the setting is mistaken, the accident such as
burning of the magnet will occur. Moreover, when the resonance point
tracking function is used, calibration is done by this data. If the setting iswrong, there might be a possibility that calibration can not be done.
As the data setting changes with the main body used, set it to an appropriate
value with surely reading P.51, when you change the data of the F/V curve.

please select also the full wave for the F/V curb. But, when calibration for
the resonance point tracking is done, please calibrate with H (Half wave).
After completing the calibration, please start the driving after switching to F

When the output is ON, the space between the terminal AL1 and theterminal C1 is short-circuited at the internal Tr.
Because the latest error data (protection function operation content) arememorized up to three, the memorized content can be displayed with UP
key and DOWN key. The content of an error that actually occurs at
maintenance etc. can be confirmed afterwards. Because data is
automatically overwritten, data cannot be changed or cleared by operation.
When data is set to 1, it rewrites all data and frequency of the function into
the initial values at shipping from NTN. It is used when resetting from the
beginning or clearing data content for return from error. All the values aresubstituted into the initial values, therefore record the present values first.
The data change can be effected only by pressing STOP key and Up key
or DOWN key simultaneously because of the operational error prevention.
It automatically returns to a normal mode after rewriting the data.
Therefore leave the external control signal in the state of "Stop."

It stores data of the resonance frequency obtained by the auto-calibration.
Moreover, when the difference of this data and the driving frequency
exceeds 20Hz, it outputs the abnormality of FE3 (resonance frequencylost) indicating that some problem occurred on the vibration main body.
As data change is possible when the driving is stopping, manual setting is
also possible.
It sets the gain adjustment data of the vibration sensor. When calibration was
done, the value is automatically written. But manual writing is also possible.
When driving by other than the constant voltage mode, gain adjustment(calibration) in advance is necessary without fail.
It sets the max output voltage at the time of implementing the calibration
for the resonance point tracking. When it is changed, please set J06 to 0.
It sets by % corresponding to the 100/200 V power source voltage. As theamplitude comes out larger at the time of driving by the resonancefrequency, there is a possibility that the movable iron core hits unless themax. voltage is curbed. When the movable iron core his during thecalibration, please down the figure and try the calibration again.
It sets the phase difference with the vibration main body at the time of drivingby the resonance point tracking mode. When it is changed, please set J06 to 0.
When vibration pulsates and it is not outspreaded by the soft switch, please try
to change this figure. As either changing to the＋side or to the－side depends
on the driving conditions of the main body, please confirm it on the actual

Panel lock
In order not to have the set value changed even if an operator touches the knob by mistake, it isrecommended to turn on the panel lock during the automatic operation. There are two kinds of panel locks,
an operation lock set by the function and a simple knob lock.
・ The operation lock can turn the function on and off by the function J00, and prohibits all the operations
and changes in data, excluding minimum necessary functions.
・ The knob lock is a function that locks the data simply, and locks only the data of the voltage value,
the % speed and the frequency. Other operations and changes in data are possible. This lock is not amechanical lock but it is the one to prohibit the operation of changing data electrically.

Data setting of multi-speed driving
The data for the multi-speed driving has two methods, the method to write data directly in the function andthe method to transfer the present driving data. The method to write directly is a method to examine both thefrequency and the voltage data or the speed % data due to driving in advance and write the value as thedata of the corresponding function №. (Refer to the page of Function).
The method to transfer the driving data is a method to transfer/overwrite the data that is driving themachine now to the directly corresponding function. Setting is done as follows. Please transfer the data whiledriving without fail. When the data is transferred while stopping, vibration will stop because the output
voltage of 0V is transferred. When you want to transfer the data at the time of the constant amplitude modeor the resonance point tracking mode, please drive by respective mode. The corresponding function(H12-H17 or H18-H20) is selected automatically according to the present driving mode.

(3) Resetting
Please reset it according to the following instructions when
the protection function operates and the driving is stopped. The
warning function for such as work shortage is an automatic
reset.
①Please certainly make the external control signal "Stop." When it
is on driving side, there is a possibility of becoming abnormal again
according to circumstances because it begins to movesimultaneously with the return.
②Please make the knob of speed adjustment to "0: turn completelycounterclockwise."③It is possible to reset it by pressing the function key or turning off thepower supply switch once (LED turning off + five seconds). However,abnormality of the hardware detection (over current etc.) can bereset only by "turning off power supply switch." Please turn off thepower when it is not possible to reset it even if the function key ispressed.
④Please investigate the cause according to the content of theoperating protection function, and take actions such as checking of
the wiring and the load, or replacement if necessary. Please work
after turning off the main power supply without fail when there is apossibility to touch the energized part when wiring etc. isconfirmed.
⑤Please clear all data by the function J10 after resetting when an
memory abnormality (Er2) comes out. However, all data returns to
the default value when the data is all cleared, therefore set data
again without fail before driving (Please inquire of the document
submitted or the vendor about the data before it is cleared). Even
under the condition that memory abnormality comes out, it ispossible to enter the function mode by long pressing the function
key. Please refer to P.23-48 for the modification method of thefunction and the frequency. Additionally, we recommend that theexternal control signal is made "Stop" because there is a possibility
that the parts feeder begins moving at the same time with thereturn when all cleared.
*Please contact NTN when it is not possible to reset it.

and a fire.
1) As for the measurement of the PWM wave shape,
the instruction value is different according to theEarthmeasuring instrument used. Please regard the

Yellow／Greenindicated value on the controller's operation panel
to be main, and treat the instrument reading as areference value.
2) All the measurement ranges are basically "AC", butthere are some equipments which have “DC”

※Leak current and earth leakage breaker
When you install an earth leakage breaker, please select the one of 200mA or more for the sensible
current. It is because there is a leakage current of a high harmonic wave to the earth in the controller ofthe inverter method. Although the leakage current of the controller during driving is about 1mA, thevibration main body changes depending on the driving condition. Therefore it should be about 10mA/unit
as a standard.

Please note controller’s inrush current when you install a protection equipment such as an earth
breakage breaker. Please select the one of an appropriate current rating from the characteristic
graph of the breaker so that the breaker does not work with the inrush current. Moreover, when pluralcontrollers are connected, the inrush current also becomes larger. When number of controllers
increase, please devise measures such as using plural breakers or turning on the power source
staggering the time.
It corresponds to 15.0 to 250.0Hz of the outdated microcomputer type controller (K-EC646 etc.).
It is for the power supply voltage of 200V (100V) or more. When the power supply voltage falls, themaximum output voltage is limited by the power supply voltage.
The output voltage stability level is a value when the setting of the output voltage is 60-170V (200V
power supply) and 30-80V (100V power supply).
As the constant amplitude performance changes according to the setting conditions of the vibration main
body, it is not a guaranteed value. Moreover, please note that it is not possible to follow the swift speed
change (incl. drive stopping) as the responsive performance becomes slow.
Various adaptive functions are installed besides the items shown. Please refer to P.5 for details.
Underlined main bodies are inapplicable to resonance point tracking mode. Moreover, there is apossibility that SMD feeder is unusable even at constant amplitude mode if frequency used is very high.
Even with vibration main body, there is a possibility that it is unusable depending on the using conditions(Change of number of leaf springs, use of extremely heavy inapplicable bowl, and modified main bodyetc.)

2. The cause due to which the fuse is cut is investigated, and proper measures are given.
3. The panel fixing screw is loosened, and the panel is opened. (Refer to P .10)
4. The cap comes out a little forward when twisting the cap of the fuse holder (Refer to P .6) under theelectric power terminal board counterclockwise by 90° while lightly pushing it to the interior, andpull out the cap as it is.
5. The fuse (cartridge) comes out with the cap too, then remove the fuse from the cap.
6. Please push a new fuse of the same rating as the broken fuse (confirm the current rating/voltageetc.) into the cap. Please dispose of the broken fuse in an appropriate manner.
7. Insert the cap and the cartridge into the fuse holder, and twist the cap clockwise by 90 degrees withpushing it to the interior to lock. Since the position (direction of the rotation) in which the cap enters
is decided, do not push it forcibly.)
8. Close the panel as before, and fix it with the machine screw.
9. After safety is confirmed, the main power supply (main breaker) is turned on.
