Table 20 Inverter Fault Codes (continued)
Fault
code Fault
Possible cause
Checking
A B
F 14 Inverter over-
temperature Temperature of heat sink is over acceptable
operating level +90°C (194°F).
Over-temperature warning is issued when
the heat sink temperature exceeds +85°C
(185°F) Check:
ambient temperature
inverter cooling fan operation
cooling air flow through heat sink
heat sink is not dirty X
F 16 Parameter P1.4.1 has value “1” or “2” Change Parameter P1.4.1 to value “0” X
F 22
F 23 EEPROM
checksum fault Parameter save error
interference fault
component failure (control unit)
After power off the inverter will automatically
reset parameter settings. The drive does not
work properly nor enable driving after this
fault.
Check:
all parameter settings.
+24V voltage output loading
If the fault comes again, contact authorized
service center. x
F 25 Microprocessor
watchdog-fault interference fault
component failure (control unit) Reset: switch power off and restart after the
lamps of display are off.
If the fault comes again, contact service
center. X
F 39 Device removed Option board removed. Reset the fault
Check option board connection X
F 40 Device unknown Unknown option board or drive. Check board and drive type. X
F 41 IGBT
temperature IGBT transistors is calculated to be over
heated
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 x
F 44 Device changed Option board changed. Reset the fault X
F 45 Device added Option board added. Reset the fault X
F 51 Stop limit S12 or S22 signal is inactive Reset: keep controller at zero >300ms.
Check control mode selection P1.1.11
Check the state of inputs DID4 and DID5,
V2.3
Hoisting application: check Dold settings X
F 56 Generator side
current limit The inverter cannot stop with the set ramp
stretching, it will stop by brake and show
F56
Too short deceleration time Reset has an additional 5 s time delay.
Check:
deceleration time X
F 60 Parameter fault “Motor selection” parameter P1.2.2 has
value = “Not Used” Download parameters again X
F 73 Both drive
commands active S1 and S2 signals on over 500ms in same
time
The inverter stops according “Stop Function”
parameter
Short circuit in pendent cable Check:
digital I/O cabling X
A = Can be done by the user
B = Can be done only by manufacturer authorized personnel
