12.4 About Alarms
Alarms indicate conditions that may affect drive operation or application performance.
Alarms are automatically cleared when the condition that caused the alarm is no
longer present.
There are two alarm types, as described in table 12.3.
The drive indicates alarm conditions in the following ways:
• Ready LED on the drive cover (see table 12.1).
• Alarm name and bell graphic on the LCD OIM. The alarm is displayed as long as the
condition 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 10 for the parameter descriptions.
