9.3 Inverter fault codes
If any of the following failures is found, the inverter displays the fault code and closes the mechanical brake
causing the movement to stop. If several faults occur one after another, the latest one is displayed, the others
are stored to fault history page.
When inverter fault supervision trips, the FAULT indicator turns on and the blinking fault code “F xx“ (xx = fault
number) appears on the display.
D2T includes an automatic fault reset operation; the fault code stays on the display until the fault is removed
and the controller released back to 0-position. Some of the fault codes require to switch the power off before
run is possible.
The faults are stored to the fault history, from there they can be seen if necessary. The fault history can store
last 30 fault codes. Following exceptions exist when storing faults to the fault history
- not stored faults: F6, F70
- repeated faults are stored only once: F50, F51, F55, F60, F66, F71, F72

Possible cause
Checking
F 1 Overcurrent Inverter has measured too high current (over 4*In) in
the motor output: Reset: switch power off and restart after the lamps
of display are off.
Check:
F 2 Overvoltage DC-bus voltage has exceeded 135% maximum
level, 911Vdc Reset has an additional 5s time delay.
Check:
F 3 Earth fault Current measurement has sensed unbalance in
motor phase currents. Supervision level is 5% of
inverter nominal current Reset has an additional 5s time delay.
Check:
F 5 Charging switch Charging switch is open when START command
becomes active Check:
If the fault comes again, change the control unit.
F 6 External Stop
Fault is not stored into fault history.
Check:
F 7 Saturation trip Very high overload or defective component Reset: switch power off and restart after the lamps
of display are off.
Check:
- sudden heavy load increase
- short circuit in the motor or cable
- brake operation
- not suitable motor
- motor type and power rating
- wrong motor parameters
- parameters
- motor cable connection
- motor insulation
-
motor loading
- supply voltage raised >1.35 x Un (high
overvoltage spikes at mains or not sinusoidal
wave form)
- Adjust the acceleration time longer
- measure main supply voltage level and wave
form while not driving
- Deceleration time is too short
- motor insulation
- motor cable insulation (phase-ground, phase-
phase)
- braking resistor cable
- braking resistor type and resistance
- braking chopper operation
- motor insulation
- not symmetric load
- motor cable insulation (phase-ground, phase-
phase)
- insulation failure in the motor or the cables
- control unit and power unit connections
- charging resistors - interference fault
-
component failure
- Either the ES or RDY-signal has been tripped
during run
- ES and RDY external connections
-
-
motor and motor cable insulation
