5.2 Alarm Display Table
The re-engineered SERVOPACK model CACR-SR††BF has the same alarm function as that of Σ-III series
SERVOPACK.
If an alarm occurs, the servomotor can be stopped by doing either of the following operations.
• DB stop: Stops the servomotor immediately using the dynamic brake.
• Zero-speed stop: Stops the servomotor by setting the speed reference to “0.”
