10.1 Alarm Displays

The following sections describe troubleshooting in response to alarm displays.

The alarm name, alarm meaning, alarm stopping method, alarm code output, and alarm reset capability are

listed in order of the alarm numbers in 10.1.1 List of Alarms.

The causes of alarms and troubleshooting methods are provided in 10.1.2 Troubleshooting of Alarms.

10.1.1 List of Alarms

This section provides list of alarms.

Servomotor Stopping Method

If an alarm occurs, the servomotor can be stopped by doing either of the following operations.

Gr.1: The servomotor is stopped according to the setting in Pn001.0 if an alarm occurs. Pn001.0 is factory-set

to stop the servomotor by applying the DB.

Gr.2: The servomotor is stopped according to the setting in Pn00B.1 if an alarm occurs. Pn00B.1 is factory-set

to stop the servomotor by setting the speed reference to

"

0.

"

The servomotor under torque control will

always use the Gr.1 method to stop. By setting Pn00B.1 to 1, the servomotor stops using the same
method as Gr.1. When coordinating a number of servomotors, use this stopping method to prevent

machine damage that may result due to differences in the stop method.

Alarm Reset

Available:Removing the cause of alarm and then executing the alarm reset can clear the alarm.

N/A:Executing the alarm reset cannot clear the alarm.
