Setting
Stops the motor in the same way as when the servo is turned OFF.
0
The motor is stopped by dynamic brake or coasts to a stop. Either of
Cn-01
these stop modes can be selected by setting bit 6 of Cn-01.
bit 8 bit 8
Stops the motor by decelerating it with the preset torque.
1
Preset value: Cn-06 (EMGTRQ) emergency stop torque
If deceleration stop mode is selected, specify the operation to be done after the motor
stops.
Setting
0 Turns the servo OFF when the motor stops in deceleration stop mode.
Cn-01 Cn 01
Causes the motor to enter zero-clamp status after it stops in deceleration

stop mode.
If torque control mode is selected for the Servopack for speed/torque control
(SGDA-jjjS), the motor stops in the same way as when the servo is turned OFF,
regardless of the setting of Cn-01 bit 8.
EMGTRQ
Emergency Stop
Cn-06
Torque
Specifies the stop torque to be applied at overtra-
vel when the input signal for prohibiting forward or
reverse rotation is to be used.
Specifies a torque value in terms of a percentage
of the rated torque.

OFF
The Servopack enters servo OFF status when:
• Servo ON input signal (S-ON, 1CN-14) is turned
OFF.
• Servo alarm arises.
• Power is turned OFF.
Specify how to stop the motor when one of the
above events occurs during operation.
