Warnings and Alarm
7 Warnings and Alarm

7.1 System Monitoring

The drive monitors the condition of its input power,
output, and motor factors as well as other system
performance indicators. A warning or alarm may not
necessarily indicate a problem internal to the drive itself. In
many cases, it indicates failure conditions from input
voltage, motor load or temperature, external signals, or
other areas monitored by the adjustable frequency drive's
internal logic. Be sure to investigate those areas exterior to
the drive as indicated in the alarm or warning.
7.2 Warning and Alarm Types
Warnings
A warning is issued when an alarm condition is impending
or when an abnormal operating condition is present and
may result in the drive issuing an alarm. A warning clears
by itself when the abnormal condition is removed.
Alarms
Trip
An alarm is issued when the drive is tripped, that is, the
drive suspends operation to prevent drive or system
damage. The motor will coast to a stop. The drive logic
will continue to operate and monitor the drive status. After
the fault condition is remedied, the drive can be reset. It
will then be ready to start operation again.
A trip can be reset in any of 4 ways:
Press [RESET] on the Keypad
Digital reset input command
Serial communication reset input command
Auto reset
Trip lock
An alarm that causes the drive to trip-lock requires that
input power be cycled. The motor will coast to a stop. The
drive logic will continue to operate and monitor the drive
status. Remove input power to the drive and correct the
cause of the fault, then restore power. This action puts the
drive into a trip condition as described above and may be
reset in any of those four ways.
