„ Servo OFF Stop Mode Selection
The SGDH SERVOPACK turns OFF under the following conditions:
• The Servo ON input signal (/S-ON, CN1-40) is turned OFF.
• A Servo alarm occurs.
• Power is turned OFF.
Specify the Stop Mode if any of these occurs during operation.
Note: If the servomotor is stopped or rotating at extremely low speed when
the items above are set at 0 (dynamic brake status after stopping with
the dynamic brake), then braking power is not generated and the ser-
vomotor will stop the same as in coast status.

Uses the dynamic brake to stop the servomotor.
Maintains dynamic brake after the servomotor stops.
1 Uses the dynamic brake to stop the servomotor.
Releases dynamic brake after the servomotor stops,
and the servomotor coasts to a stop.
2 Coasts the servomotor to a stop. The servomotor is
turned OFF and stops due to equipment friction.

The dynamic brake electrically applies a
brake by using a resistor to consume
servomotor rotation energy.
