3.5.4 Causes and remedies

Fault message

Description Cause Remedy

No. Display

−−− −−− No fault − −

0011 OC1 Short circuit of motor cable

Short circuit  Search for cause of short circuit.

 Check motor cable.

Excessive capacitive charging current in the

motor cable.

Use motor cable which is shorter or of

lower capacitance.

0012 OC2 Motor cable earth fault One of the motor phases has earth contact.  Search for cause of short circuit.

 Check motor cable.

0015 OC5 I x t overload  Frequent and too long acceleration with

overcurrent

 Continuous overload with I

motor

> 1.05 x

rx.

Check drive dimensioning.

0016 OC6 I

x t overload TRIP (motor, C0120) Current overload of the motor, e.g. due to:

 frequent or too long acceleration

processes

 impermissible continuous current

 Check drive dimensioning.

 Check setting of C0120.

x018 OC8 I

xt overload advance warning  Frequent and too long acceleration

processes with motor overcurrent.

 Permanent motor overload with

motor

rmotor

Check drive dimensioning.

1020 OU Overvoltage in DC bus Braking energy is too high.

(DC−bus voltage is higher than set in

C0173.)

 Use braking unit or regenerative module.

 Check dimensioning of the brake

resistance.

1030 LU Undervoltage in the DC bus DC bus voltage is lower than specified in

C0173.

 Check mains voltage

 Check supply cable

x032 LP1 Motor phase failure

A current−carrying motor phase has failed.  Check motor.

 Check motor cable.

 Switch off monitoring (C0597 = 3).

The current limit value is set too low.  Set higher current limit value via C0599.

0050 OH Heatsink temperature > +90 °C

Ambient temperature

> +40 °C or > +50 °C

 Allow module to cool and ensure better

ventilation.

 Check ambient temperature in the

control cabinet.

Heatsink is very dirty. Clean heatsink.

Wrong mounting position Change mounting position.

x053 OH3 Motor temperature

> +150 °C threshold

(temperature detection via resolver or

incremental value encoder)

Motor is thermally overloaded due to:

 Impermissible continuous current

 Frequent or too long acceleration

processes

 Check drive dimensioning.

 Switch off monitoring (C0583 = 3).

No PTC/temperature contact connected. Correct wiring.

x054 OH4 Heatsink temperature > C0122

Ambient temperature T

> +40 °C or

> +50 °C

 Allow module to cool and ensure better

ventilation.

 Check ambient temperature in the

control cabinet.

 Switch off monitoring (C0582 = 3).

Heatsink is very dirty. Clean heatsink

Wrong mounting position Change mounting position.

The value specified under C0122 is set too

low.

Enter a higher value under C0122.

x057 OH7 Motor temperature > C0121

(temperature detection via resolver or

incremental value encoder)

Motor is thermally overloaded due to:

 Impermissible continuous current

 Frequent or too long acceleration

processes

 Check drive dimensioning.

 Switch off monitoring (C0584 = 3).

No PTC/temperature contact connected. Correct wiring.

The value specified under C0121 is set too

low.

Enter a higher value in C0121.
