Fault Description
Action to Take
Op Error Fault
F11
Internal error.
Reset drive to factory defaults.
Open Pot Fault
F9
An external pot is connected and the ground lead of the pot is
disconnected creating a potential drive overspeed hazard.
Check the external potentiometer circuit at TB2, terminals 1, 2
and 3 for an open circuit.
Overcurrent FauIt
F12
Overcurrent is detected in overcurrent hardware trip circuit.
Check for a short circuit at the drive output or excessive load
conditions at the motor.
Overload Fault
F7
Internal electronic overload trip.
An excessive motor load exists. It must be reduced such that
drive output current does not exceed the % of current set by the
[Overload Current] parameter. Reduce [Start Boost]
Overspeed Fault
F25
Internal error.
Reset drive to factory defaults.
Overtemp Fault
F8
Temperature sensor detects excessive heat.
Check for blocked or dirty heat sink fins. Check for proper
mounting and spacing (See page 2-1). Check if the ambient
temperature limit has been exceeded.
Overvolt Fault
F5
DC bus voltage exceeded maximum value.
Monitor the AC line for high line voltage or transient conditions.
Bus overvoltage can also be caused by motor regeneration.
Extend the decel time or install dynamic brake option.
