10.1.2 Alarm Display Table
Alarm display, names, and meanings are shown in table 10.1.
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.”
