Installation conditions of the converter will greatly affect its life and reliability. Avoid installing it in
the places listed below. Use it under the environmental conditions described in {Chapter 9 Standard
Specifications}.
(1) In a humid and dusty area or a place where water or oil drips, the insulation of circuits is deteriorated,which may reduce the life of parts.
(2) Too high ambient temperature will cause the life of the main circuit capacitor or the cooling fan to be
reduced.
(3) In a place containing corrosive gas, connectors may have a loose connection, electrical wires may bedisconnected, and parts may be damaged.

12(4) In a place having many vibrations, connectors may have a loose connection, electrical wires may bedisconnected, and parts may be damaged.
(5) When using the converter in a place where ambient temperature is below 0 ℃, use a heater, etc. to ensurethat it becomes 0 ℃ or higher at the start of the converter. After it starts, when the temperature becomes
0 ℃ or higher due to its heat generation, there is no problem.
■ Action after short-circuit
Dispose of a short-circuited converter in any circumstances without using it.

Caution Installation● Install the converter on non-inflammables such as metal.
Otherwise, a fire may occur.
● Do not put inflammables near the converter.
Otherwise, a fire may occur.
● 75 kW and higher grade models are heavy. Do not attempt to raise it alone.
Otherwise, you may be injured.
● Do not hold the front cover when transporting the converter.
It may fall, which can result in injury.
● Install the converter in a place which can support its weight.
It may fall, which can result in injury.
● Do not install and operate the converter which is damaged or has a missing part.
Otherwise, you may be injured.
● Do not install the converter in an atmosphere which contains plasticizer such as halogen and DOP (phthalate ester).
Otherwise, it may be damaged.

■ Converter installation requirements and heat radiation
To use the converter, incorporate it into the control board, etc. to meet the environmental conditions for
installation.

Warning How to install converter● Install it correctly.
Incorrect installation can result in a risk of electric shock or a fire.

･ Installation orientation and intake/exhaust direction
Install the converter vertically with a cooling fan facing up. When it is installed sideways, ventilation isprevented, which may increase temperature. You should sufficiently consider a path of intake and exhaust.
The cooling fan built in the converter sucks air from the bottom and exhausts it to the top. To prevent a wiringduct, etc. from blocking up the vent, keep enough space.
･ Keeping cooling space
To install the converter, keep a cooling space.
When heat generation devices exist in the surrounding environment, place them so that they do not affect coolingof the converter and others.
The operating temperatures of the converter are 0 to 50 ℃. To install it in the control board, perform ventilation
to ensure that the temperature in the board is below 50 ℃. High ambient temperature will decrease reliability.

(1) Input the specified input voltage. Inputting 400 V to the 200 V class converter damages the unit and causes
a very dangerous situation.
(2) Be sure to connect MCCB of appropriate capacity to the main circuit input side.
(3) Be sure to connect the power supply line to RA, SA and TA. Connect so that the main circuit terminals [L1/R],[L2/S] and [L3/T] correspond to RA, SA and TA, respectively.
(4) Be sure to connect to the ground terminal for safety reasons.
(5) To connect five or more inverters between the converter outputs of [+] and [-], you may need to connect
an adjustment resistor between the RR and R terminals. In this case, contact us.
(6) The AC power supply terminals [MR] and [MT] for the control circuit are not connected to the power supply
in normal situations. Connect them when the control circuit power needs to be turned on after turning off
the main circuit power. Be sure to insulate from the main circuits of [L1/R], [L2/S] and [L3/T] using atransformer.
When the control power supply terminals [MR] and [MT] are used in parallel models (VF66R-15022, 18022,
and 40044 through 100044), power should be supplied to not only a master unit but a slave unit.
19(7) The AC reactor used in the PWM sine wave mode is different from that used in the 120-degree conduction mode.
Be sure to use the AC reactors specified by Toyo Denki.
(8) A filter capacitor is required in the PWM sine wave mode. It is not used in the 120-degree conduction mode.
Be sure to use the filter capacitor specified by Toyo Denki.
(9) Never connect the GND and COM terminals of the control circuit to the ground terminal.
(10) In the factory default, the control input terminal [START] and multifunction input terminals [MI1] through[MI5] are set to PS common input (source input). When changing them to GND common input (sync input), remove
a jumper socket on the control board <VFC66R-Z> from [CN-SO] and then attach it to [CN-SI].

Changing a short-circuit wire
To use the VF66R-31544 or 16044 converter at a power supply voltage of 460 V, you need to change a short-circuit
wire.

block shown on the right.
・460V: Short circuit between [MCA] and [RA1] on the terminal blockshown on the right.

* Notes for connecting multiple inverters to the converter
1. Up to five inverters can be connected to a single converter.
Be sure to select the converter having a rated capacity larger than the total capacity of inverters touse.
For example, when total five 400 V class inverters of 11, 15, 22, 37 and 45 kW are used, the total capacity
is 130 kW and therefore VF66R-16044 should be selected.
Note that in using the PWM sine wave mode, the effect of suppressing distortion of power supply current
is decreased at a capacity half the converter rated capacity or less. In this case, it is possible touse as a converter. To produce the harmonic suppression effect, however, it is recommended that the loadon the converter be more than half of the rated capacity.
2. To use the converter as a common converter for multiple inverters, connection of a resistor between theterminals R and RR may be needed depending on the number of inverters to be connected.
For the resistance value and model, contact us.

Danger Wiring● Never touch the terminals while the converter is energized. A voltage is applied to the converter output terminals even in
the stopped state.
Otherwise, it can result in a risk of electric shock.

3.5. Notes for Wiring and Electrical Wire Size
3.5.1. Notes for Wiring(1) Input the specified voltage into the converter terminals [L1/R], [L2/S], [L3/T], [+] and [-].
･ If you input the voltage specified for the 400 V class into the 200 V class converter,
the converter will be damaged.
･ If you input the voltage specified for the 200 V class into the 400 V class converter,
it may lead to malfunction or damage to the converter.
(2) IGBT is used in the converter, and the converter operates at a high frequency. Therefore, noise is emitted.
Consider the following points for wiring:･ Keep main circuit wires away from a control signal wire. When placing them in parallel, keep a distanceof 30 cm or longer between them.
･ When crossing them, ensure that they are crossed at right angles.
･ It is recommended that the main circuit wire should be contained into a metal pipe as a measure against
noise for other facilities.

Chapter 4 Basic Operating Procedures for Converter
4.1. Checks before Starting Operation
4.1.1. About the Control Mode
The VF66R converter provides two control modes: PWM sine wave mode and 120-degree conduction mode.
You can check which mode is selected with the console display at power-on or setting item: <n-00>.
The console display shows "VF66r" for the PWM sine wave mode or "Vr120" for the 120-degree conduction mode.
(Note) Normally, the unit is shipped with the control mode specified by order.
Notes･ Note that the AC reactor used in the PWM sine wave mode is different from that used in the 120-degree conductionmode.
･ The PWM sine wave mode uses a filter capacitor, whereas the 120-degree conduction mode does not. Keep thisin mind.
･ With the PWM sine wave mode selected, the terminal MI3 on the terminal block TB1 on the control board <VFC66R-Z>
needs to be input. If the terminal MI3 is not input with the PWM sine wave mode selected, the converter cannot
be operated. Conversely, if the terminal MI3 is input with the 120-degree conduction mode selected, theconverter cannot be operated. Keep this in mind.

4.1.2. Minimum Parameter Settings
1. Power supply frequency
Set via the basic setting item "2.FrEq."
2. Electric constant of filter
To use the unit in the PWM sine wave mode, check that the constants of the AC reactor and filter capacitor(specified by Toyo Denki) connected to the VF66R converter are correctly set in the items: <A-00> and <A-01>
in the setting area. (The values of the AC reactor and filter capacitor specified by Toyo Denki are set
at the time of the control board <VFC66R-Z> initialization.)
Be sure to use the AC reactor and filter capacitor specified by Toyo Denki.

4.1.3. Replacing Control Board <VFC66R-Z> with Spare
To make a spare compatible with the currently used converter, gain adjustments of analog circuits, such as
converter capacity and DC voltage detection part are necessary.

You can shift the operating digit to the right by pressing the [→] key. Shifting to the left is possible
only when setting a parameter using the [←] key. If you press the [→] key while the operating digit isin the right edge of the seven-segment display, it moves to the leftmost digit or the maximum settable digit.
Likewise, if you press the [←] key while the operating digit is in the left edge of the seven-segment display
or the maximum settable digit, it moves to the rightmost digit.
(2) To change numerical values
How to set a negative value in the seven-segment display on the console
Use the [→] or [←] key to move the operating digit to the leftmost one and then use the key [↑] or [↓]to change a number.
･ By pressing the [↑] key
A number changes in the following order: "0" -> "1" -> "2" ･･････ "8" -> "9" -> "-." After "9," a negativevalue is displayed.
･ By pressing the [↓] key
A number changes in the following order: "0" -> "-" -> "9" ･･････ "3" -> "2" -> "1." After "0," a negativevalue is displayed.

5. Press the [SET] key.
･ The selection of "d-18" is confirmed, and for example its
Initialize.Val "0.100" is displayed as a current setting value.
･ The display of the setting value automatically returns to thatof the setting item in ten seconds.
6. Press the [MONI/FNC] key.
･ The [FNC] LED turns off, and the console returns to the monitor (MONI) mode.
･ The monitor item, which was displayed before setting the parameter, is displayed for about one second. Then,
its data is displayed.

Operating digit of parameter setting items● When setting items of the area A through area S are displayed, an alphabet character or a number blinks, which indicatesthe operating digit.
● Each time the [→] key is pressed, the operating digit moves in the following order: alphabet character -> number inthe tens digit -> number in the ones digit -> alphabet character.
● When a number in the ones digit is changed, in some cases, a number in the tens digit is also changed. For example:･ A value changes in the following manner: "d-09" -> "d-10," "d-19" -> "d-20" or "d-99" -> "d-00" by pressing the [↑]key.
･ A value changes in the following manner: "d-10" -> "d-09," "d-20" -> "d-19" or "d-00" -> "d-99" by pressing the [↓]key.

■ How to change parameter setting values
To manually set and change parameters of the converter, perform the following steps on the console:For example, this section provides procedures for changing the parameter d-18 of the area d from its
Initialize.Val "0.100" to "0.080."
1. When the [FNC] LED on the console is off, press the [MONI/FNC] key.
･ The [FNC] LED turns on, and the console enters the function setting (FNC) mode.
･ A setting item appears in the seven-segment display on the console. For example, immediately after the converter
is turned on, the first item of the basic setting area is displayed.
2. Press the keys [↑] or [↓] to display the first setting item "d-00" of the area d.
･ The alphabet character "d" in the setting item blinks, whichindicates the operating digit.

38

3. Press the [→] key to blink numbers, and then press the keys[↑] or [↓] to change them to become "d-18."

4. Press the [SET] key.
･ The selection of "d-18" is confirmed, and "0.100" is displayed
as a current setting value.
･ The operating digit blinks. In the initial setting, the maximum
digit within the Setting range (in this case "0" in the ones
digit) blinks.
･ The display of the setting value automatically returns to thatof the setting item in ten seconds.
5. Press the keys [↑] or [↓] to change the display to "0.000."･ As a result, "0.000" is displayed.

6. Press the [→] key once and then press the keys [↑] or [↓] to change it to "8."･ As a result, "0.080" is displayed.

7. Press the [SET] key.
･ The change is confirmed, and "d-18" is displayed again.
･ The display of the setting value automatically returns to thatof the setting item in ten seconds. Unless the [SET] key ispressed while a setting value is displayed,
it is not confirmed.
･ To change other parameters, repeat the procedures from the step2.
8. Press the [MONI/FNC] key.
･ The [FNC] LED turns off, and the console returns to the monitor (MONI) mode.
･ The monitor item, which was displayed before setting the parameter, is displayed for about one second. Then,
its data is displayed.

Operating digit of parameter setting values● The operating digit of a setting value is indicated by blinking.
･ A number from "0" to "9," a minus sign "-," or an underscore "_" (representing a blank) blinks.
● Immediately after the setting value is displayed, the maximum digit within the Setting range of that parameter blinks.
Therefore, immediately after the setting value is displayed, which becomes the operating digit depends on parameters.
● For example,･ When selecting one of selecting items "0" to "3": A number in the ones digit blinks.
･ When "150" is set in the Setting range of "0" to "150": "1" in the hundreds digit blinks.
･ When "80" is set in the Setting range of "0" to "150": An underscore blinks in the hundreds digit.
● However, note that the display of the setting value of the parameter automatically returns to that of the setting itemin ten seconds.

5.3. Detailed Explanation of Each Parameter5.3.1. Basic Setting Area
In the basic setting area, the commonly used basic setting items to operate the converter are summarized.
Settings such as DC voltage command and power-factor angle via the console are performed in this area.
Before operating the converter, be sure to set each parameter according to the power supply specification.
Of the units shown in the table, only "Hz," "A," "V" and "kW" can be displayed on the standard console. Other
units cannot be displayed.

DC voltage setting: 0.VrEF
Set the DC voltage command for the case that the DC voltage command fixed mode selection: <d-00> is set to ON.
With the DC voltage command fixed mode selection: <d-00> set to OFF, the DC voltage command variation mode isentered and thus this setting is ignored.
For the DC voltage command variation mode, refer to the description of setting items in the area d in this manual.
Setting with the console can be done in increments of 0.1 V for the 400 V class unit. However, the setting isreflected in increments of 0.2 V internally. Keep this in mind.
* Caution
A DC voltage cannot be made lower than a value obtained by "effective value of AC line voltage x 1.56 (V)."When a value obtained by "effective value of AC line voltage x 1.56 (V)" becomes higher than the setting of"0.VrEF," a DC voltage command becomes a value obtained by "effective value of AC line voltage x 1.56 (V)."
Note that the maximum DC voltage command is 358 V (200 V class)/716 V (400 V class).

55

Power-factor angle: 1.PHi
Set the power factor for the AC side. This item is set by power-factor angle. A negative value indicates delayphase operation of current relative to the power supply voltage, whereas a positive value indicates advancephase operation. The power factor is a cosine value of the setting.
Power supply frequency: 2.FrEq
Set the frequency of the AC power supply.

DC voltage command fixed mode selection: d-00
Select whether to use the fixed mode for the DC voltage command.
OFF: The DC voltage command variation mode is entered, and the DC voltage command varies with the AC voltage.
In this case, the DC voltage command is determined as follows:DC voltage command = Effective value of AC line voltage x DC
voltage command gain: d-01
ON: The DC voltage command fixed mode is entered, and the DC voltage command is fixed to the setting of thebasic setting item "0.VrEF."(Refer to the description of basic setting item 0.VrEF in this manual.)
DC voltage command gain: d-01
When the DC voltage command fixed mode selection: d-00 is set to OFF, the DC voltage command becomes a value
obtained by "effective value of AC line voltage x d-01."
DC voltage command upper limit: d-02
Set the upper limit of DC voltage command for the case that the DC voltage command fixed mode selection: d-00
is set to OFF.

Set the lower limit of DC voltage command for the case that the DC voltage command fixed mode selection: d-00
is set to OFF.
* Caution
A DC voltage command cannot be set lower than a value obtained by "effective value of AC line voltage x 1.56
(V)."
66

When a value obtained by "effective value of AC line voltage x 1.56 (V)" becomes higher than the setting ofd-02 (DC voltage command upper limit), a DC voltage command becomes a value obtained by "effective value of
AC line voltage x 1.56 (V)."
Note that the maximum DC voltage command is 358 V (200 V class)/716 V (400 V class).
When the DC voltage command source selection: b-03 is set to a value other than "0," the DC voltage commandfrom the specified place takes priority.
For d-02 and d-03, setting with the console can be done in increments of 0.1 V for the 400 V class unit. However,the setting is reflected in increments of 0.2 V internally. Keep this in mind.

FCL (high-speed current limit) level setting: F-01
In this parameter, set a FCL (high-speed current limit) value. Typically, set it to 100%.
With this parameter set to 100 %, when an instantaneous current, which is 2.86 times the rated AC current of
the converter unit, flows to any phase, the FCL function turns off all the outputs of converter phases to protect
the converter (the converter outputs will be turned on automatically when the current drops). If turning on/off
of output by the FCL function persists for ten seconds, the converter is stopped by continuous FCL protection
operation.

DC voltage detection gain: L-00
This parameter indicates detection adjustment gain of DC voltage detected by the converter.
By inputting the voltage between the DC terminals [+] and [-] during converter initialization, this DC voltage
detection gain is back calculated and the resulted value is set to this parameter. Normally, use it withoutchanging the initialized value.
When the gate board <GAC66>, etc. is replaced, an error may occur between "Vdc" display on the console and theactual voltage between the DC terminals [+] and [-]. In this case, to adjust DC voltage detection gain without
initializing memory, refer to {5.4.3. DC Voltage Detection Gain Adjustment}.
