5) Temporary stop/restart
When TSTP (Temporary stop/restart) is switched on during automatic operation, the servo motor
decelerates with the deceleration time constant of the point table being executed, and then stops
temporarily.
Switching on TSTP (Temporary stop/restart) again starts the servo motor rotation for the
remaining travel distance.
During a temporary stop, ST1 (Forward rotation start) or ST2 (Reverse rotation start) does not
function even if switched on.
When any of the following conditions is satisfied during a temporary stop, the travel remaining
distance is cleared.
The automatic operation mode is switched to the manual operation mode or homing mode.
The servo amplifier enters the servo-off status.
The clear signal is inputted.
The temporary stop/restart input functions in the following status.
