ZHOME input
When the ZHOME input is turned ON, the motor will move to the home position set by the HOME PRESET switch or
MEXE02
. Since it does not require sensors, return-to-home is possible at high-speed.
FREE input
When the FREE input is turned ON, the motor current will be cut off . When an electromagnetic brake motor is used,
the electromagnetic brake will be released. The motor output shaft can be rotated manually since the motor holding
torque is lost.
Do not turn the FREE input ON when driving a vertical load. Since the motor loses its holding torque,
the load may drop.
STOP input
When the STOP input is turned ON, the motor will stop. When resuming the operation, input the operation start signal
or pulse to the driver after turning the STOP input OFF.
When the motor was stopped by the STOP input while the motor is operated by inputting pulses, be
sure to turn the pulse input OFF. If the STOP input is turned OFF while inputting pulses, the motor
may suddenly start rotating.
If the STOP input is turned ON while the motor is operated by inputting pulses, the driver is not
allowed to receive the pulse input.
ALM-RST input
If the ALM-RST input is turned from OFF to ON while an alarm is generated, the alarm will be reset. (The alarm will be
reset at the ON edge of the ALM-RST input.) Before resetting an alarm, be sure to remove the cause of the alarm to
ensure safety. Note that some alarms cannot be reset with the ALM-RST input.
When the motor is operated by inputting pulses, turn the pulse input OFF before resetting the alarm.
FW-JOG input, RV-JOG input
These signals are used to start JOG operation.
The motor continuously operates in the forward direction when turning the FW-JOG input ON, and the motor
continuously operates in the reverse direction when turning the RV-JOG input ON. If the signal having inputted is
turned OFF, the motor will stop.
