•
Motor power rating too low for the
application
O P F
Motor phase failure
•
Loss of phase at drive controller
output
•
Downstream contractor open
•
Motor not connected
•
Instability in the motor current
•
Drive controller oversized for motor
•
Check the connections from the drive
controller to the motor
•
Test the drive controller on a low power
motor or without a motor: set OPL to nO
O S F
Over voltage during
steady state
operation or during
acceleration
•
Line voltage too high
•
Line supply transients
•
Check the line voltage. Compare with the
drive controller nameplate rating
•
Reset the drive controller
P H F
Input phase failure
•
Input phase loss, blown fuse
•
Three-phase drive controller used
on a single-phase line supply
•
Input phase imbalance
•
Transient phase fault
NOTE: This protection only operates
with the drive controller running
under load
•
Check the connections and the fuses
•
Verify that the input power is correct
•
Supply three-phase power if needed
C F F
Configuration Fault
•
The parameter configurations are
not suited to the application
•
Restore the factory settings or load the
backup configuration, if it is valid
U S F
Under Voltage
•
Line supply too low
•
Transient voltage dip
•
Damaged precharge resistor
•
Check the line voltage
•
Replace the drive controller
