3.1.2 Setting the Overtravel Limit Functioncont.

Setting Meaning
Cn-01
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
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 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.

Setting: 1
For Speed/Torque Control
and Position Control
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.

Dynamic brake is a function that
electrically applies brakes by using a
resistor to consume motor rotation
energy.
