0011 OC1 Short circuit of motor cable

Short circuit l Search for cause of short

circuit.

l 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.

l Search for cause of short

circuit.

l Check motor cable.

0015 OC5 I x t overload l Frequent and too long

acceleration with overcurrent

l Continuous overload with

motor

> 1.05 x I

rx.

Check drive dimensioning.

0016 OC6 I

xt overload l Frequent and too long

acceleration processes with

motor overcurrent.

l Permanent motor overload

Check drive dimensioning.

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

(DC−bus voltage is higher than set

in C0173.)

l Use braking unit or

regenerative module.

l Check dimensioning of the

brake resistance.

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

specified in C0173.

l Check mains voltage

l Check supply cable

x032 LP1 Motor phase failure

A current−carrying motor phase

has failed.

l Check motor.

l Check motor cable.

l Switch off monitoring

(C0597 = 3).

The current limit value is set too

low.

l Set higher current limit value

via C0599.

0050 OH Heatsink temperature > +90 C

Ambient temperature

> +40 C or > +50 C

l Allow module to cool and

ensure better ventilation.

l Check ambient temperature in

the control cabinet.

Heatsink is very dirty. Clean heatsink.

Wrong mounting position Change mounting position.
