FC CONVERTER OVERTEMPERATURE
C1:Temperature of heatsink over +75C
A1:Check: cooling air flow. Check: that sink is not dirty. Check: ambient
temperature. Check: that switching frequency is not too high compared
with ambient temperature and motor load
1515
FC MOTOR STALLED
The load on the drive motor is too high (detected by current measurement on
drive inverter output)
C1:Driving mechanics inhibited or blocked
A1:Check driving mechanics for blocking (for example, gear at geared
drive, oiling). Check brake for proper opening.
C2:Sudden heavy load increase
A2:Check for impermissible loading
1516
FC MOTOR OVERTEMPERATURE
C1:The Vacon frequency converter motor temperature model has
detected motor overheat- motor is overloaded
A1:Check the THMH sensor on the ACVF. Check the cable connection.
Verify the sensor is KTY type. Check: Decrease motor load. Check: the
temperature model parameters if the motor was not overheated
1517
FC MOTOR UNDERLOAD
The load on the drive motor is too low (detected by current measurement on
drive inverter output)
C1:Driving mechanics broken
A1:Check driving mechanics for breakage (for example, gear at geared
drive, ropes, etc.)
1518
FC ANALOGUE INPUT FAULT
C1:
–
Wrong analogue input polarity
–
Component failure on control board
–
Irrelevant for Schindler Closed Loop application
A1:Check: polarity of the analogue input, Check: replace frequency
converter
1519
FC OPTION BOARD IDENTIFICATION
C1:Reading the frequency converter option board has failed
A1:Check: installation, if installation is correct replace frequency
converter.
1520
FC 10V SUPPLY REFERENCE
C1:+ 10 V reference shorted on control board or option board
A1:Check: the cabling from +10V reference voltage
1521
FC 24V SUPPLY
C1:+ 24 V reference shorted on control board or option board
A1:Check: the cabling from +24V reference voltage
