Appendix A — Fault Codes

When a fault is detected by the inverter control electronics, the drive is stopped and the

symbol F together with the ordinal number of the fault, the fault code and a short fault

description appear on the display. The fault can be reset with the RESET button on the

control keypad or via the I/O terminal. The faults are stored in the Fault History Menu M5,

which can be browsed. Table A-1 contains all the fault codes.

Table A-1: Fault Codes



Programmable.

Fault

Code Fault Possible Cause Solution

1 Overcurrent Inverter has detected too high a

current (>4xI

) in the motor cable:

• sudden heavy load increase

• short circuit in the motor

• unsuitable motor

Check loading.

Check motor.

Check cables.

2 Overvoltage The DC-link voltage has exceeded

the limits deﬁned in Table 1-4:

• too short a deceleration time

• high overvoltage spikes in supply

Set the deceleration time longer.

Add a brake chopper or brake

resistor.

3 Ground Fault



Current measurement has detected

that the sum of motor phase currents

is not zero.

• insulation failure in cables or

motor

Check motor cable and motor.

5 Charging Switch The charging switch is open, when

the START command has been

given.

• faulty operation

• component failure

Reset the fault and restart.

Should the fault re-occur, contact

your Cutler-Hammer distributor.

6 Emergency stop Stop signal has been given from the

option board.

7 Saturation trip Various causes:

• component failure

• brake resistor short circuit or

overload

Cannot be reset from the keypad.

Switch off power.

DO NOT RE-CONNECT POWER!

Contact Eaton.

If this fault appears simultaneously

with Fault 1, check motor cables and

motor.

8 System fault • component failure

• faulty operation

Note: exceptional fault data record,

see Page 5-12.

Reset the fault and restart.

Should the fault reoccur, contact

your Cutler-Hammer distributor.
