List of faults and alarms

Faults and Alarms

3-1519

SINAMICS S List Manual (LH1), 07/2007

Remedy: Generally, the following applies when an alarm message is output:

- check the line supply and fuses.

- check the line supply quality and system fault level.

- check the load.

Dependent on the alarm value in r2124, the following applies:

Bit 0 = 1: Line fault occurred or poor/incorrect controller setting. For poor line quality or frequent line supply

changeover operations, when required, limit value p3463 can be increased until the alarm value no longer occurs.

Bit 2 = 1: Line fault occurred or poor/incorrect controller setting. - check the controller setting and load.

Bit 3 = 1: Line fault occurred. For poor line quality or frequent line changeover operations, when required, limit values

p0284 and p0285 can be increased until the alarm value no longer occurs.

Bit 4 = 1: Line interrupted or line overvoltage has occurred.

Bit 5 = 1: Line interrupted or line undervoltage has occurred.

Bit 7 = 1: Peak current trip due to line fault or overload. Check the load.

Bit 8 = 1: Line fault occurred.

Bit 9 = 1: Line undervoltage or overload. Check the load.

Reaction upon F: NONE (OFF1, OFF2)

Acknowl. upon F: IMMEDIATELY (POWER ON)

F06210 Infeed: Summed current too high

Drive object: A_INF, B_INF, S_INF

Reaction: OFF2 (OFF1)

Acknowledge: IMMEDIATELY (POWER ON)

Cause: The smoothed sum of the phase currents (i1 + i2 + i3) is greater than 4 % of the maximum power unit current (r0209).

Possible causes:

- the DC link has a ground fault that results in a high summed current (r0069.6). The DC component in the line cur-

rents can damage/destroy the power unit, commutating reactor or line filter!

- the zero point calibration of the current measurement was not carried out (p3491, A06602).

- defective current measurement in the power unit.

Fault value (r0949, floating point):

Smoothed sum of the phase currents.

Remedy: - check the DC link for a low-ohmic or high-ohmic ground fault and if one is present, remove.

- increase the monitoring time of the current-offset measurement (p3491).

- if required, replace the power unit.

A06215 (F) Infeed: Summed current too high

Drive object: A_INF, B_INF, S_INF

Reaction: NONE

Acknowledge: NONE

Cause: The smoothed sum of the phase currents (i1 + i2 + i3) is greater than 3 % of the maximum power unit current (r0209).
