Code Fault Possible cause Suggested solution Resetting
34 Internal Bus
Communication
• Internal bus error • Switch off supply voltage
• If problem recurs, replace
inverter
B
35 Application Fault
• Internal application error • Switch off supply voltage
• If problem recurs, replace
inverter
B
41 IGBT
Overtemperature
• Internal IGBT temperature
too high
• Wait for unit cooling down C
52 Parameter Fault • Wrong parameter setting.
P1,9 Drive Selection = 0
• Check parameter P1.9 Drive
Selection
C
53 CAN
Communication
Fault
• CAN Communication is not
working
• Switch off supply voltage
from all devices that are
connected to CAN bus
• Check CAN-bus wiring and
termination resistor settings
• Check CAN-communication
parameters
C
55 Board Fault • API3 is not installed or not
working properly
• Switch off supply voltage
• Check API3 supply voltage
• Check API3 wiring
connections
• If problem recurs, replace
inverter
B
56 Generator Current
Limit/Deceleration
Ramp Supervision
• Inverter cannot stop with the
set ramp stretching
• Increase P1.8 Deceleration
Time or P11.1 Ramp
Stretching value
C
57 Motor
Overtemperature
• Motor temperature too high
• Digital input DIA4
deactivated when used for
motor overtemperature
protection
• Wait for motor cooling down
• Avoid running long periods at
low speed
• Check motor temperature
protection wiring
C
58 Overvoltage
Regulator Timeout
• Overvoltage regulator has
been active for 5 sec
C
59 Overvoltage at Start • Too high supply voltage • Measure supply voltage and
check hoist supply voltage
from hoist type plate
C
60 Power unit fault • Power unit has stopped
running
• E-stop during running
• Switch off supply voltage
• Check power unit wiring
• If problem recurs, replace
inverter
