(3) Temporary stop/restart during automatic operation
When TSTP is turned ON during automatic operation, the motor is decelerated to a temporary stop at the
deceleration time constant in the point table being executed. When TSTP is turned ON again, the
remaining distance is executed.
Forward rotation start (ST1) or reverse rotation start (ST2) is ignored if it is turned ON during a temporary
stop.
The remaining moving distance is cleared when the operation mode is changed from the automatic mode
to the manual mode during a temporary stop.
The temporary stop/restart input is ignored during a home position return or during JOG operation.
