Fault code Possible cause Checking
F 57
Thermistor fault Thermistor input in relay / thermistor
board has detected motor
overtemperature. Fault appears when
thermistor input has been open over 1s. Check:
− motor cooling and loading
− thermistor connection. If expansion board
thermistor input is not used, it should be
shorted
− motor parameters
− the brake operation
F 60
Parameter fault Inverter has lost parameters. Drive
selection parameter has changed to 0 /
none. Download parameters from keypad
F 61
Overspeed Fault SSU has tripped to Overspeed
(hardware supervision). Motor speed
has increased above overspeed
detection level. Reset when 1s without pulses from pulse
sensor/encoder to SSU and controller at zero
position.
Check:
− function and cabling
− maximum frequency setting parameters
− SSU settings
F 62
Speed Difference
Fault SSU has tripped to Speed Difference Reset when 1s without pulses from pulse
sensor/encoder to SSU and controller at zero
position.
Check:
− pulse sensor/encoder function and cabling
− pulse sensor/encoder pulse number
− speed difference supervision settings
F 63
Stall Supervision
Fault SSU has tripped to Stall Reset when 1s without pulses from pulse
sensor/encoder to SSU and controller at zero
position.
Check:
− brake operation
− pulse sensor/encoder function and cabling
− stall supervision settings
F 64
SSU Relay Test Fault Relay in SSU board is damaged, SSU
relay is bypassed or OK input is
damaged. Reset: switch power off and restart after the lamps
of keypad are off.
Check:
− ES and RDY external connections
− OK input operation
− change SSU board
F 65
SSU Watchdog SSU internal fault
− interference fault between SSU
board and control board
− component failure (control board or
SSU board)
Check:
− SSU status (System menu / System info /
Expander boards / C: SSU / status)
− SSU LED’s
If the fault comes again, contact authorized
service
F 66
SSU Overspeed Limit SSU overspeed limit has been set over
140% of maximum frequency Check:
− set SSU overspeed limit under 140% of
maximum frequency
− motor type plate parameters
− maximum frequency parameters
F 70
Multicare Fault Other D2H/D2C has tripped to fault or
brake of other D2H/D2C has not been
opened. Fault is not stored into fault
history. Check other D2H/D2C:
− fault history
− brake operation
− brake relay control delay settings
F 71
Brake Control Fault Load information from load measuring
device is out of operation window Check
− Ain2 wiring
− settings of load measuring device
F 72
Brake Feedback Fault Brake is opening or closing in wrong
time Check:
− brake operation
− brake relay (ROB2) and brake contactor
(K7/K71) operation
