Setting Meaning
Cn-01
bit 8
0
Stops the motor in the same way as when the servo is turned OFF.
The motor is stopped by dynamic brake or coasts to a stop. Either of
these stop modes can be selected by setting bit 6 of Cn-01.
bit 8
1
Stops the motor by decelerating it with the preset torque.
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 Meaning
Cn 01
0 Turns the servo OFF when the motor stops in deceleration stop mode.
Cn-01
bit 9 1
Causes the motor to enter zero-clamp status after it stops in deceleration
stop mode.
If torque control mode is selected, the motor stops in the same way as when the
servo is turned OFF, regardless of the setting of Cn-01 bit 8.

reverse rotation is to be used.
Specifies a torque value in terms of a percentage
of the rated torque.

For Speed/Torque Control
and Position Control
The Servopack enters servo OFF status when:
• Servo ON input signal (S-ON, 1CN-40) is turned
OFF.
• Servo alarm arises.
• Main power is turned OFF.
Specify how to stop the motor when one of the
above events occurs during operation.
Setting Meaning
C 01
0 Stops the motor by dynamic brake.
Cn-01
bit 6 1
Causes the motor to coast to a stop.
The motor power is OFF and stops due to machine friction.
