P a g e 0 1 / 0 7 / 1 9
O L F
Motor Overload
•
Thermal trip due to prolonged
motor overload
•
Motor power rating too low for
the application
•
Allow the motor to cool before restarting
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
