Service Manual
rev 5.0 with software Ind1V022
-
measure main circuit diodes and IGBT
transistors
- If the fault comes again, change the power
unit.
F 8 System fault System
fault due to component failure or faulty
operation
.
Reset: switch power off and restart after the lamps
of keypad are off.
Check:
If the fault comes again, change the D2V.
F 9 Undervoltage DC-bus voltage has dropped below 333Vdc In case of temporary supply voltage break, reset the
fault and start again. Check mains input.
F 10 Input line
supervision One input line phase is missing.
F 11 Output phase
supervision Current supervision has sensed that one of the
motor phases has no current Check:
F 12 Braking chopper
supervision Braking chopper or braking resistor circuit has
failed. Test pulse measures transistor collector
voltage. Fault appears if Reset: switch power off and restart after the lamps
of display are off.
Check:
F 13 Inverter
undertemperature Temperature of heat sink is below acceptable
operating level (-10°C /14°F) Check
F 14 Inverter
overtemperature Temperature of heat sink is over acceptable
operating level
+90°C (194°F).
Overtemperature warning is issued when the heat
sink temperature e85°C (185°F) Check:
F 22
F 23 EEPROM checksum
fault Parameter save error After power off the inverter will automatically load
factory default parameter settings. D2T does not
work properly nor enable driving after this fault.
Check:
F 24 Changed data
warning Changes may have occurred in the different counter
data due to mains interruption No special actions required. Take a critical attitude
to the counter data.
F 25 Microprocessor
watchdog-fault Reset: switch power off and restart after the lamps
of display are off.
If the fault comes again, contact service.
F 26 Power Unit Fault
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 35 Application fault Run-time exception in the application program Contact authorized service.
F 36 Control Unit Faulty Control Unit. Contact authorized service.
F 37 Device changed Option board changed. Reset the fault
F 38 Device added Option board added. Reset the fault
F 39
Device removed Option board removed. Reset the fault
F 40 Device unknown Unknown option board or drive. Check board and drive type.
F 41 IGBT tempetature Too high temperature in IGBT transistors. Reset: switch power off and restart after the lamps
of keypad are off.Check:
- read fault extension code and contact
authorized service
- mains supply voltage interrupted
- If mains supply is correct, an internal failure
has occurred. - inverter fault can also cause an undervoltage
trip
- Contact authorized service. - external fault during run may cause an
undervoltage trip
Check:
- supply voltage
- mains connection.
- motor cable connections
- measure motor phase currents and compare
to display value
- braking resistor is broken
-
braking resistor and insulation resistance
-
braking chopper is broken
-
measure braking transistor IGBT and free
wheeling diodes
-
braking resistor is not installed
-
If resistor is OK, then the chopper is broken
- Contact authorized service
- ambient temperature
- cubicle heating
-
ambient temperature
-
inverter cooling fan operation
- cooling air flow through heat sink
- heat sink is not dusty
- interference fault
- component failure (control unit)
- all parameter settings.
- +24V voltage output loading
- If the fault comes again, contact authorized
service.
- interference fault
- component failure (control unit)
- long duration overload
- motor parameters - lowered cooling
- u/f curve settings - high environment temperature
- motor loading
- brake operation
