after power supply OFF (during the period from power supply OFF to LED turning off).
When the subsequent power supply is turned on, it is likely to stop with Er2.
There is a distinction between the ground phase and non-ground phase in the power supply. Pleaseconfirm the earth phase side of the power supply, and connect controller's specified terminal to theearth phase side. (Refer to 11).
There is a possibility of causing a fire when the wiring is grounded.
Please install the leak breaker or the leak detector on the primary side of power supply of thecontroller for the ground fault protection. Especially, please install it surely when it is not possible toconnect it to the ground phase. There is a possibility of causing a fire when the wiring is grounded.
Surely connect the earth clip of the welding machine to the bowl when welding to the bowl. An
incorrect connection of the earth for the welding may burn the earth cable that connects the main
body and the controller, and fears such as electric shock, leaks, and the burn of the controller exist.
Please don’t conduct the welding work without turning off the power supply or the main breaker on the
primary side of the controller. There is a possibility of causing damage of the controller.
Please select and use an appropriate cable according to the voltage used, the current, and theenvironment. There is a fear of a leak or a fire when a wrong cable is used.
It doesn't stop immediately even if the power is cut off during the driving. Moreover, the run/stop key iseffective only when the function is set. Therefore, when you urgently stop the machine when thedriving is controlled from the outside, please stop it by using the external control signal.
Please set the F/V curve and the current rating before driving the main body.
When making a mistake in the setting, the magnet might be damaged by firing.
Be sure not to install or drive a damaged controller or a controller which is lack in parts.
There is a fear of an injury.
The noise is generated from the controller or wiring and equipments connected to the controller.
Please take care that neither a peripheral equipment nor the sensor will malfunction. There is a fear ofan accident.
*Note:

Please execute the dielectric breakdown test with AC1500V or less between AC line and the earth, andDC500V or less between DC line and the earth. The leakage of current shall be 10mA or less. Moreover,during the test, the high pressure is charged in the internal capacitor. Be careful enough so as not to get an
electric shock.

Terms appearing frequently in this Instruction Manual
1. "Parts feeder" means generic names of such as bowl feeders and linear feeders, and for NTN products only.
2. The one only written as main body indicates “Vibration main body of parts feeder”.
3. The one only written as LED indicates the data display portion on the operation side (Refer to P.6).
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 isachieved. 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
automatically changes to 100V output or 200V output according to the power-supply voltage. When the AC200V
output is necessary for the AC100V input, please change to the type equipped with AC100V power source unit
K-UE083.
(3) Overload protection (Refer to P.19, Function J01 in P.30）
When the current rating of the connected load is set, the output voltage is controlled automatically so as not toexceed this current value. While this function is operating, LED displays alternately the output voltage and OL
for the attention to be drawn. When it is not possible to solve it even if the output voltage is lowered down to 20V
or lower, the driving is stopped and an emergency warning (continuous lighting of OL) is issued. This function isapplicable for a set value of the current rating over 0.2A, Setting is possible for 0.2A or less, but it becomesinaccurate.
(4) Multi-speed function (Refer to P.18, Function H11 to 17 in P.35, and P.37）
Three kinds of speed data can be memorized internally, and the speed can be changed by the switch signal
from the outside. Moreover, non-step (1V unit) control of the output voltage by the analog voltage is possible.
(5) Enhancement of the protection function
Driving is stopped to protect the controller and peripheral equipments and the circuit arrangement when output
short-circuit, earth fault*1, overload, decrease in power-supply voltage*2 etc. occur.
*1

The earth fault in this controller means the short-circuit with the earth on the output side. Please note thatthe protection against neither the earth fault in the internal circuit nor the leak is effective.

*2

When the power-supply voltage decreases, LV is displayed and the driving is stopped. When the
power-supply voltage returns, the controller returns automatically too. Please note that the driving begins
when the operating conditions are complete.

(6) Panel lock (Refer to P.36）
The operation from the operation panel can be prohibited if necessary. A wrong operation by an operator orunintended change of setting by his/her contact etc. can be excluded. Two kinds of locks, the operation lock andthe knob lock, are installed according to the restricted range.
(7) Timer for air-blow and input/output terminal are equipped (Refer to P.15 to 17 and P.33 to 34）
Because the control circuit of the solenoid valve for the air blow is included as standard equipment, the controlof air-blow during driving or two rows AND air-blow etc. can be easily used.
(8) Work shortage detection function (Refer to P.19, Function H08 to H10 in P.34 to 35）
The work shortage detection timer is installed.

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 and the trouble due to the noise especially when the transformer is set commonly with otherequipment. Please consult the transformer maker about details of the problem when supplying the power to thecontroller (inverter). Please refer to the paragraph of the input in P.43 for controller's inrush current. Moreover,to reduce the influence by the noise, the use of the shielded wire or wiring of a distance as short as possible isrecommended.

The cable length of signal input line (24V, +V, X1, 0V) should be within 10m. Adopt a twist wiring if it ispossible.

In case of no external control used
When the external control terminal is not used, make function J02 setting as "1" and have theexternal control input terminal short-circuited (at two positions of 24V-+V and X1-0V). The controller
drives continuously. Even if the setting of J02 is made "0" and the external control input terminal is

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
and outlet, then when the work exists, the sensor at the chute inlet turns the parts feeder OFF, andwhen the work 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 controllingthe normal 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.16~17, 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.

Note on wiring
Analog signal line (A1,0V) treats a minute voltage. Therefore takecare for the wiring such as that the length shall be within 5m and theshielded wire is used. The noise becomes the change of set value

As an abnormal signal, any of above signals outputs according to the setting of the function J12.
Driving is stopped and an emergency signal is output when the abnormality detection circuit or the
CPU detects the above four abnormalities (the space between C2 and EM is short-circuited in abnormal
circumstances). An abnormal signal continues to come out until the abnormality is released. An
abnormal content of this time is displayed in LED.
Moreover, abnormal signals can be used also as driving instruction output (the same behavior as
Y1A-Y1C) or driving preparation completion signal.

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 keys 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.36) 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 ECH45). 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
ECH45) or more before driving. Possible set range is 0.10~2.50A (0.10~5.00A
for ECH45) but the use range is 0.20~2.00A (0.50~4.50A for ECH45). For theparts feeder of less than 0.2A (0.5A for ECH45), 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 ECH45), set to
0.2A (0.5A for ECH45) to use in order not for the overload warning function tooperate. If setting at less than 0.20A (0.5A for ECH45), it is necessary to set
correcting the error of instruction value by the electric power meter for
inverter.
For ECH45, 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
ECH45) only to the short-time operation such as for the adjustment. Driving
for more than 30 minutes exceeding 2.00A (4.50A for ECH45) makes the lifeof controller 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.38), 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 arealternately 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 or 2).
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 the terminal
EM. (Refer to P.39)

Description
Set the time of the timer that detects the work shortage. When the signal continues
for a set duration, the work shortage signal is set. The logic with which the timer
works depends on H00 or H03, and the timer works when the input selected with
H08 during driving (output ON) is Low (the reverse-operation is also possible by
H00 or H03). At time-up, NoP is displayed on LED as a work shortage signal, andterminal AL1 turns ON (selected with J08).
Set the time of the timer that resets the work shortage signal. When the signal
continues for a set duration, the work shortage signal (timer) is reset. The logic withwhich the timer works depends on H00 or H03, and is the same operation as the
OFF delay timer (the work shortage signal is reset). The noP display disappears by
resetting, and AL1 also turns OFF.

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 andthe frequency. Other operations and changes in data are possible. This lock is not a mechanical lockbut 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 thefrequency and the voltage data due to driving in advance and write the value as the data of thecorresponding function №.
The method to transfer the driving data is a method to transfer the data that is driving the machine now tothe directly corresponding function. Setting is done as follows. Please transfer the data while driving. Whenthe data is transferred while stopping, vibration will stop because the output voltage of 0V is transferred.
①The parts feeder is driven by the driving data to be memorized.

driving to protect the load.
When operation time abnormality of CPU is detected, it
stops the controller's driving. When it can not be reset bypower supply OFF, it is very likely to be breakdown.
The controller's driving is stopped by detecting the memory
abnormality (abnormal value is found in the set data).
(Refer to ⑤ of the next page)(2) Warning function
The warning function is a convenient function to transmit a state of driving or various kinds ofinformation. When “Overload warning” and “Work shortage” of the warning function operated, the signalof the content set by the function is output to between terminals C1-AL1 (transistor output). When thewarning action is released, warning is also reset automatically.

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 plural controllers 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. 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 of the 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 astandard.
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, the maximum 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).
Various adaptive functions are installed besides the items shown. Please refer to P.5 for details.

6. Please push a new fuse of the same rating as the broken fuse (confirm the current rating/voltage etc.) into thecap. 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 with pushing itto the interior to lock. Since the position (direction of the rotation) in which the cap enters is decided, do notpush 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.
