R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice.

The drive 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

code

Fault

Possible cause

Checking

F 1 Overcurrent

Inverter has measured too high current (over

4*In) in the motor output:

• sudden heavy load increase

• short circuit in the motor or cable

• not suitable motor

• wrong motor parameters

Reset: switch power off and restart after the lamps of

display are off.

Check:

• brake operation

• motor type and power rating

• parameters

• motor cable connection

• motor insulation

• motor loading

F 2 Overvoltage DC-bus voltage has exceeded 135%

maximum level, 911Vdc

• supply voltage raised >1.35 x Un (high

overvoltage spikes at mains or not

sinusoidal wave form)

• Deceleration time is too short

Reset has an additional 5s time delay.

Check:

• Adjust the deceleration time longer

• measure main supply voltage level and wave form while

not driving

• motor insulation

• motor cable insulation (phase-ground, phase-phase)

• braking resistor cable

• braking resistor type and resistance

• braking chopper operation

F 3 Earth fault Current measurement has sensed

unbalance in motor phase currents.

Supervision level is 5% of inverter nominal

current

• not symmetric load

• insulation failure in the motor or the cables

Reset has an additional 5s time delay.

Check:

• motor insulation

• motor cable insulation (phase-ground, phase-phase)

F 5 Charging

switch

Charging switch is open when START

command becomes active

• interference fault

• component failure

Check:

• control unit and power unit connections

• charging resistors

• If the fault comes again, change the control unit.

F 6 External Stop

• Either the ES or RDY-signal has been

tripped during run

• Fault is not stored into fault history.

Check:

• ES and RDY external connections

F 7 Saturation trip Very high overload or defective component

Reset: switch power off and restart after the lamps of

display are off.

Check:

• motor and motor cable insulation

• 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:

• read fault extension code and contact authorized service

• If the fault comes again, change the D2V.

F 9 Undervoltage DC-bus voltage has dropped below 333Vdc

• mains supply voltage interrupted

• inverter fault can also cause an

undervoltage trip

• external fault during run may cause an

• In case of temporary supply voltage break, reset the

fault and start again. Check mains input.

•

If mains supply is correct, an internal failure has occurred.

•

Contact authorized service.
