16. HOW TO USE THE POINT TABLE
(e) Temporary stop/restart
When "Controlword bit 8 (HALT)" 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. When "Controlword bit 8 (HALT)" is switched off during a temporary stop, the servo
motor starts for the remaining travel distance.
"Controlword bit 4 (New set-point)" does not function even it is switched on during a temporary stop.
When any of the following conditions is satisfied during a temporary stop, the travel remaining
distance is cleared.
The control mode is changed from the point table mode (pt) to the Jog mode (jg).
The servo motor enters the servo-off status.
The temporary stop/restart input functions in the following status.
