5 Faults and Alarms

5.1 Fault messages

In the event of a failure, the inverter switches off and a fault code appears on the

display.

NOTE

To reset the fault code, one of three methods listed below can be used:

1. Cycle the power to the drive.

2. Press the

button on the BOP or AOP.

3. Via Digital Input 3 (default setting)

Fault messages are stored in parameter r0947 under their code number (e.g. F0003 =

3). The associated error value is found in parameter r0949. The value 0 is entered if a

fault has no error value. It is furthermore possible to read out the point in time that a

fault occurred (r0948) and the number of fault messages (P0952) stored in Parameter

r0947.

F0001 Overcurrent STOP II

Quit

Remove fault and reset fault memory by disconnecting the

- drive converter from the line supply and powering-up again

- Press the Fn key on the BOP or AOP

- Acknowledge fault P2103, P2104

- P0952 (complete fault memory)

Cause

- short-circuit at the output

- ground fault

- excessively large motor (the motor power rating P0307 is greater than the inverter power r0206)

- defective final stage (end stage)

Diagnosis & Remedy

Please check the following:

- are the cable lengths within the limit values ?

- does the motor cable or motor have either a short-circuit or ground fault ?

- do the motor parameters correspond to those of the motor being used ?

- is the motor overloaded or stalled (locked rotor) ?

- increase the accelerating time.

- reduce the gain

- use a motor with a lower power rating

- is the stator resistance value (P0350) correct ?

F0002 Overvoltage STOP II

Quit

Refer to F0001

Cause

- DC link voltage (r0026) higher than the overvoltage threshold (refer to parameter r0026)

- ground fault

Diagnosis & Remedy

Please check the following:

- is the line supply voltage within the permissible range?

- has the DC current DC link monitoring been enabled (P1240) and correctly parameterized?

- extend the deceleration ramp (ramp-down time P1121, P1135)

- remove the ground fault

- is the required braking power within the permissible limits?

NOTE

- a higher moment of inertia requires longer deceleration times; if required, use a braking resistor.

- overvoltage can either be caused by an excessively high line supply voltage or by the fact that the motor

is generating (regenerative mode).

- the motor can be generating as it is decelerating quickly or due to the fact that an active load is driving

the motor.
