− interference fault
− component failure (control unit)
If the fault comes again, read fault extension
code and contact authorized service.
F 26
Power Unit Fault
Faulty power unit Contact authorized service.
F 31
IGBT temperature
Too high temperature in IGBT
transistors. A hardware temperature
measurement has tripped.
Reset: switch power off and restart after the
lamps of keypad are off.
Check:
− motor loading
− brake operation
− inverter heatsink
− inverter cooling fan operation
− environment temperature
F 32
Fan cooling fault
Cooling fan of the frequency
converter do not work, when ON
command has been given
If the fault comes again, contact authorized
service.
F 34
CAN bus
communication
Sent message not acknowledged Ensure that there is another device on the
bus with the same configuration

Faulty Control Unit Contact authorized service.
F 37
Device changed
Option board or power unit has
been changed to same type
Reset the fault.
F 38
Device added
Option board of same type or drive
of same power rating added
Reset the fault.
F 39
Device removed
Option board removed. Drive
removed.
Reset the fault.
F 40
Device unknown
Unknown option board or power
unit.
Check the type of option board or control unit
and power unit.
F 41
IGBT temperature
Too high temperature in IGBT
transistors.
− long duration overload
− lowered cooling
− high environment temperature
Reset: switch power off and restart after the
lamps of keypad are off.
Check:
− motor loading
− brake operation
− inverter heatsink
− inverter cooling fan operation
− environment temperature
F 43
Encoder failure
Encoder failure.
− Code1 = EA+/- is missing
− Code2 = EB+/- is missing
− Code3 = Both EA+/- and EB+/-
are missing
− Code4 = EA+ and EB+ are
crossconnected
Check:
− encoder cabling
− brake opening
− encoder mechanical assembly
− encoder type and pulse number
F 44
Device changed
Option board or control unit has
been changed to different type or
different power rating
Reset the fault. Option board parameters or
all parameters are set up to default values.
F 45
Device added
Option board of different type or
drive of different power rating added
Reset the fault. Option board parameters or
all parameters are set up to default values.
