Clearing a Fault
If the unit is programmed to automatically restart after a particular fault, the display indicates that the
unit will restart and will count down the seconds remaining to restart on the display. The countdown can
be interrupted by pressing and holding both arrow keys. The load will immediately restart.
For faults that allow an automatic restart, the default number of restarts after a fault is zero. If the end
user desires the unit to automatically restart after a fault, the number of restarts allowed and the time
between fault and restart must be programmed in the
CHANGE PARAMETER VALUES > AUTO
RESTART PARAMETERS
for that fault.
If the drive has exceeded the programmed number of auto restarts, or if auto restarts have not been
enabled, the display will indicate the fault on the top line and the second line will read
RESTART?
ENTER
. Press ENTER to clear the fault and restart the load. The fault counters in the Restart Log will
all be reset to zero. See
Section 4.8
Restart Log
, for more information.
The
ENABLE RESTART
parameter allows the drive to restart automatically after a fault. This
parameter also enables the drive to initialize in AUTO mode when the input power has been cycled
OFF/ON and the drive is energized. The factory default setting does not allow auto restarts. Navigate
to this parameter via
CHANGE PARAMETER VALUES > AUTO RESTART PARAMETERS >
ENABLE RESTART
for values in setting the parameter.
Certain faults do not allow an auto restart. These faults generally indicate the possibility of damage to
the drive and/or the load, or indicate the possibility of a dangerous condition. When this type fault
occurs, the display will read
NO AUTO RESTART
. When this type fault occurs, contact the factory for
assistance before restarting or troubleshoot the system thoroughly. These faults can be cleared only by
cycling input power OFF/ON.
There are several conditions where the drive will indicate a fault but the fault will not be recorded in the
fault log. These faults occur only when the drive is energized from utility mains and is initializing. If any
of three conditions including ground fault, high input voltage or low input voltage is detected, the display
will indicate the fault and wait for the condition to resolve before entering normal operating mode. If
these conditions occur after the drive has initialized, a fault will be logged and can be cleared in the
normal manner.
WARNING:
The drive may start automatically without warning when operating conditions permit.
Make certain input power is disconnected before servicing the unit or its connected loads.
