ALARM-RESET input
Use the ALARM-RESET input if you need to move the motor to a specified position
or the mechanical home position after the motor has stopped in the middle of
operation due to an actuation of the driver’s protective function (ALARM output:
OFF).
After the motor has been moved, check and remove the cause of the alarm and then
reset the alarm.
The ALARM can also be reset when the power supply is cycled.
For ALARM conditions, see page 37.
When the motor is stopped, turn on this signal; then turn it off. This will allow
ALARM to be reset.
Before inputting the ALARM-RESET, reset either the START/STOP or
RUN/BRAKE input to the OFF. If both are ON, ALARM-RESET input will not be
accepted.
