Warnings and Alarms
The table below lists the drive fault messages and indicates whether a
warning, alarm, or trip-lock occurs. Wherever an X is placed under
both warning and alarm, this means that a warning precedes the alarm.
An alarm always precedes, or simultaneously accompanies, a trip-lock.
A trip causes the drive to suspend operation by cutting off power to the
motor. A trip-lock requires that input power to the drive be removed, the
cause of the fault corrected, and the input power restored in order to
reset the drive.
A trip can be reset in any one of the following ways:
1) Manual reset by pressing the RESET key on the keypad
2) A digital input through a digital input terminal
3) Serial communication command
4) Automatic reset
Automatic or manual reset may be selected in parameter 400,
Reset
Function.
Auto reset will not restore a trip-lock. The number of reset
attempts may be selected or infinite, which allows continuous attempts. A
timer between attempts can be set in parameter 401.
