(4) 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 servomotor operation.
• Forward run prohibited input (P-OT, CN1-7)
• Reverse run prohibited input (N-OT, CN1-8)
The torque limit is specified as a percentage of rated torque.

Parameter Description
Pn001 n. 0 Stops the servomotor the same way as changing to Servo OFF (according to Pn001.0).
n. 1 Decelerates the servomotor to a stop at the preset torque value or less, and then locks the
servomotor in Zero Clamp Mode.
Torque setting: Pn406 emergency stop torque
n. 2 Decelerates the servomotor to a stop at the preset torque value or less, and puts the
servomotor in coast status.
Torque setting: Pn406 emergency stop torque
Pn406 specifies the stop torque applied for overtravel when the input signal for prohibiting forward or reverse rotation is
used.
