Frequency Converter Error Message
1501
FC OVERCURRENT
The maximum current limit on one or more drive inverter output phases to the
drive motor has exceeded
C1:Short circuit in the motor cables or motor windings
A1:Check power wires and connectors between drive inverter and drive
motor.Check motor for short circuit at windings.
C2:Driving mechanics inhibited or blocked
A2:Check driving mechanics for blocking (for example, gear at geared
drive, oiling) Check brake for proper opening.
C3:Sudden heavy load increase
A3:Check for impermissible loading
C4:Drive parameter setting
A4:Check drive parameter and compare with motor type and its data
C5:Unsuitable drive motor
A5:Check drive motor for correct dimensioning in the elevator system
1502
FC OVERVOLTAGE
*)
Overvoltage at the drive inverter internal DC link detected
C1:Deceleration is too high
A1:Adjust the deceleration (proposal 0.5 m/s2)
C2:High over-voltage spikes at mains
A2:Check mains voltage for disturbances and tolerances
C3:Drive inverter electronics failure
A3:Replace drive inverter
1503
FC EARTH FAULT
The sum of the phase currents of the drive inverter output to the drive motor is
not equal zero
C1:Earth fault
A1:Check power wires (insulation) to the motor. Check motor for short-
circuit at motor windings
C2:Creeping current
A2:Check power wires (insulation) to the motor. Check motor for short-
circuit at motor windings
1504
FC INVERTER FAULT
C1:Vacon frequency converter has detected faulty operation in the gate
drivers or IGBT bridge - interference fault (EMC)- component failure
A1:- Reset the fault and restart. If the fault occurs again replace
frequency converter.
