About Alarms

Alarms indicate conditions that may affect drive operation or application performance.

There are two alarm types, as described in table 5.2.

The drive indicates alarm conditions in the following ways:

Ready LED on the drive cover (see table 5.1).

Alarm name and bell graphic on the LCD OIM (see Appendix B). The alarm is
displayed as long as the conditon exists. The drive automatically clears the alarm
when the condition causing it is removed.

Alarm status parameters. Two 16-bit parameters, Drive Alarm 1 (211) and Drive
Alarm 2 (212), indicate the status of type 1 and type 2 alarms, respectively. Refer to
chapter 11 for the parameter descriptions.
