VF66B (DC motor drive)
protection contact
(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.)
