FC ENCODER PULSE MISSING
Invalid signal from the drive motor encoder
C1:Encoder signal is faulty
A1:Check general wiring to the encoder
C2:Encoder signal is noisy
A2:Check encoder signals for right termination (terminating resistor)
C3:Encoder signal receiving stage defective
A3:Replace electronics (for example, option board or even entire drive
inverter) of corresponding device
C4:Encoder defective
A4:Replace encoder
C5:Drive Parameter set wrong
A5:Check drive parameter (for example, nominal frequency, impulse ratio
etc.)
C6:The rotation direction signaled by the encoder (differential inputs) is
contrary to the drive motor mains phase sequence
A6:Change encoder direction parameter (CF 16, PA 14)

FC ENCODER DIRECTION
*)
Wrong rotation direction signal from the drive motor encoder
C1:The rotation direction signaled by the drive motor encoder
(differential inputs) is contrary to the drive motor mains phase sequence
A1:Change encoder direction parameter (CF 16, PA 14)
1533
FC SPEED SUPERVISION
Too high difference between reference and actual car drive motor speed. The
actual speed is derived from the incremental encoder information.
C1:Driving mechanics inhibited or even blocked
A1:Check brake for proper opening.Check driving mechanics for
blocking (for example, gear at geared drive, oiling).Check for bad weight
balancing of car and counterweight.
C2:Motor or motor encoder parameter set wrong or speed limit parameter
set too narrow
A2:Change corresponding parameter accordingly. Note that at some
drives there are several limits dedicated for the different speeds like
inspection speed, evacuation speed, etc. (for example, shaft speed
limit/time, shaft service speed limit/time)
C3:Malfunction of drive motor rotation encoder
A3:Replace the encoder.
1536
FC ANALOG INPUT UNDER CURRENT
C1:The current in the analog input line is below 4 mA.Signal source has
failed.Control cable is broken.
A1:Check: mechanical break. Check: check the motor is not running on
the current limit.Check: Increase Parameter 11.8 SpeedErrorLim without
surpassing 1/3 of rated output frequency.
