„ Servomotor Stop Mode for P-OT and N-OT Input Signals
Set the following parameters to specify the Servomotor Stop Mode when P-OT and N-OT
input signals are used.
Specify the Servomotor Stop Mode when either of the following signals is input during ser-
vomotor operation.
• Forward run prohibited input (P-OT, CN1-42)
• Reverse run prohibited input (N-OT, CN1-43)
For torque control, the servomotor will be placed in coast status after either decelerating or coasting to
a stop (according to the stop mode set in Pn001.0), regardless of the setting of Pn001.1.
Pn406 specifies the stop torque applied for overtravel when the input signal for prohibiting
forward or reverse rotation is used.
The torque limit is specified as a percentage of rated torque.

Pn001.1 0 Stops the servomotor the same way as turning the
servo OFF (according to Pn001.0).
1 Decelerates the servomotor to a stop at the preset
torque, and then locks the servomotor in Zero Clamp
Mode.
Torque setting: Pn406 emergency stop torque
2 Decelerates the servomotor to a stop at the preset
torque, and puts the servomotor in coast status.
