POINT
Explanations on the drive unit signals are the same as those for servo
amplifiers with 22kW or less. Refer to section 3.5.
Pin No.
CN1-1 Used to input 24VDC (24VDC 10% 150mA) for I/O interface. The power supply
CN1-6 capacity changes depending on the number of I/O interface points to be used.
For the source interface, connect
CN1-7 Turn EM1 off to bring the motor to a forced stop state, in which the magnetic
connector is turned off and the servo-off signal is output to the drive unit.
Turn EM1 on in the forced stop state to reset that state.
CN1-2 ALM turns off when power is switched off or the protective circuit is activated.
Without alarm occurring, ALM turns on within about 1.5s after power-on.
CN1-8 When warning has occurred, WNG turns on.
CN1-5 Common terminal for the ALM and WNG output signals of the converter unit.
CN1-9 Separated from LG.
Pins are connected internally. For the source interface, connect
external power supply.
CNP1-1 Connect to the operation coil of the magnetic contactor. Always supplies the
control circuit power since it is conducted with L
WARNING
CNP1-2 Connect to the operation coil of the magnetic contactor. When the converter unit
(Note) receives a start command from the drive unit, it is conducted with L
