Enable Potential Cause
Fixed Motor temperature or motor current, depending on
choice of over-load method, has exceeded the over-
load setting for the time specified by the over-load
timeout parameter.
SOP If motor voltage exceeds 90% of the motor over‐
voltage limit in the motor limit menu.
SOP The measured motor voltage exceeds the threshold
set by the motor trip volts (1160) parameter in the
limits menu (1120). An improperly set-up or tuned
drive usually causes this fault. This could include
the secondary tap setting. A high line condition can
also cause this.
Fixed Drive instantaneous over-current (IOC) faults usu‐
ally result when the signal from test point IOC on
the system interface board exceeds the level set by
the drive IOC setpoint (7110) parameter in the input
protect menu (7000).
SOP The torque producing current of the drive has drop‐
ped below a preset value set by the user.
Menu This fault usually indicates a loss of load condition
when the torque producing current of the drive has
dropped below a preset value set by the user for
the specified amount of time.
Fixed The software has detected an imbalance in the mo‐
tor currents.
SOP The software has detected an open phase condition
at the drive output to the motor. Generally, if this
occurs, the problem is with the feedback. A true
open output phase will result in an IOC trip.
SOP This alarm is issued when the drive is in speed roll‐
back, due to a torque limit condition, for more than
one minute.
SOP This fault or alarm, depending on the SOP program,
is issued when the drive is in speed rollback, due
to a torque limit condition, for more than 30 minutes.
SOP Motor speed is below the zero speed setting (2200).
This is either due to a motor stall condition, if speed
demand is higher than the zero speed setting, or a
low speed demand condition, where speed demand
is lower than the zero speed setting.
SOP This occurs only with synchronous motor control
due to field exciter failure or loss of power to the
exciter.
