4
Warning [Maintenance and inspection, and replacement of parts]
Before inspection, turn off the input power after checking that the motor is stopped, and then wait for over ten
minutes.
Also, check that direct-current voltage between 1 and or 2 and is less than or equal to 30 V.
Otherwise, electric shock, injury, or a fire may occur.
Check that the rated voltage of the product and the voltage of the alternating-current power supply match with
each other.
Otherwise, injury, electric shock, or part damage may occur.
Do not perform maintenance and inspection or replace parts except qualified persons.

(Note 1) You can change the control input terminal (ST-F) and multifunction input terminals (MI1 to MI5) to GND common input (sync
input). In this case, remove a jumper socket on the printed control board [VFC66-Z] from [CN-SO] and then attach it to [CN-SI].
(In the factory default, these are set to PS common input (source input).)
(Note 2) Never connect the GND and COM terminals of the control circuit to the ground terminal.
(Note 3) When the thermal relay of the dynamic braking resistor (DBR) operates, cut off the input of VF66B (DC motor drive).
(Note 4) Install the main circuit contactor (52M) according to the use of the customer.
When installing the main circuit contactor (52M) on the input side of VF66B (DC motor drive), wait for ten minutes or more from
the time the power is turned off until it is turned on again.
(Note 5) When DCL is not connected, terminals 1 and 2 are short-circuit.
(Note 6) The AC power supply terminals (MR/MT terminals) for the control circuit are provided to the models VF66B-1122, VF66B-1144
and higher. (These do not need to be connected to the power supply in a normal situation. Connect them only when the control
circuit power supply needs to be turned on exclusively, for example, when having the protection display while the main circuit
power supply is turned off.)

10
(Note 7) Use DBIF2009-Z when communicating with the printed control board [VFC66-Z] and the dynamic braking (DB) optional unit
[VFDB2009]. For more information, refer to the separate document "VFDB2009 Operation Manual."
CAUTION [Installation of SET66EX-Z (external console panel)]

This is used to detect the VF66B (DC motor drive) protection by inputting the field loss signals output from
the field amplifier when field loss occurs. However, the multifunction input terminal (3) function selection
should be set to the field loss signal (c-03=13). *For the details, refer to "6.4 Area c" in Chapter 6 and "7.4
Area c" in Chapter 7.
This is used to detect the VF66B (DC motor drive) protection by inputting the overcurrent signal which is
output from the field amplifier when field overcurrent occurs. However, the multifunction input terminal (4)
function selection should be set to the field overcurrent (c-03=14). *For the details, refer to "6.4 Area c" in
Chapter 6 and "7.4 Area c" in Chapter 7.
For power constant operation, the voltage after LC filter is input between 1 and 3 of the field amplifier for
the 440 V system motor, and between 2 to 3 for the 220 V system motor.

2.4. Application of LC filter
2.4.1. Role of LC Filter
LC filter reduces the load applied to the DC motor by smoothing the PWM control waveform (average voltage
control of the pulse width modulation by using square wave) which is output from VF66B (DC motor drive) and
reducing the peak voltage applied to the DC motor. Because the application of LC filter varies depending on
the structure of DC motor and the deterioration state of insulation, please contact us.
2.4.2. Power Constant Operation
When performing the power constant operation, please install the specified LC filter between the output of
VF66B (DC motor drive) and the DC motor. Input the voltage after LC filter to the field amplifier for weaker
field control. For how to connect the voltage input to the field amplifier, refer to "2.3 How to Connect the
Printed Control Board [VFC66-Z] and Field Amplifier" in Chapter 2.
2.4.3. Selection of LC Filter
Following L (DC reactor) and C (film capacitor) are provided. Select the number of LC filters depending on the
current of DC motor and apply them in parallel.
L1 (DC reactor) 3 mH 115 A
L2 (DC reactor) 15 mH 25 A
C (Film capacitor) 400 μF 800 V
Selection example
For DC motor, 200 kW, 440 V, 489 A, 1150 min-1:
DC motor current/DC reactor rated current = 489/115 =4.25
By rounding up the first decimal number, you get "5." Therefore, apply 5 pieces of L and 5 pieces of C in
parallel.
The following table indicates the resonance frequencies.
L C

L1 3 mH 400 μF 145 Hz
L2 15 mH 400 μF 65 Hz

3.1.2. Cooling Fan Operation
When VF66B (DC motor drive) is turned on, the cooling fan installed on it also starts at the same time. It
behaves as follows. Please keep this in mind.
State of VF66B (DC motor drive) Cooling Fan operation
Power-on It operates for five minutes after power-on and then stops.
However, when VF66B (DC motor drive) is operated within five minutes after
power-on, the cooling fan stops in one minute after VF66B (DC motor drive) stops.
Running It always operates.
Stop After VF66B (DC motor drive) stops, it operates for one minute and then stops.
3.2. Console Panel [SET66EX-Z]
VF66B (DC motor drive) has a console panel [SET66EX-Z], which is equipped with a five-digit LED display,
eight operation key buttons, a unit LED, and a state display LED, as a standard device. With this console
panel, you can operate the unit, read and write each function setting data, monitor the operating state, and
display what are protected during protection operations.
