Fault 30 SW limit switches

Subfault: 30.1

Description: Positive limit switch hit

 

Response: SW limit switches – current drive train

Cause

Measure

Positive software limit switch hit.

– Check the position of the software limit switch.

– Check the target position.

– Leave the software limit switch in the opposite direction.

Subfault: 30.2

Description: Negative limit switch hit

 

Response: SW limit switches – current drive train

Cause

Measure

Negative software limit switch hit.

– Check the position of the software limit switch.

– Check the target position.

– Leave the software limit switch in the opposite direction.

Subfault: 30.3

Description: Limit switches swapped

 

Response: Emergency stop + output stage inhibit

Cause

Measure

Position of negative software limit switch greater than position of positive software limit switch.

Check the positions of the software limit switches.

Subfault: 30.4

Description: Distance of software limit switches too small/noise suppression window too large

 

Response: Emergency stop + output stage inhibit

Cause

Measure

The range limited by the positive and negative software limit switches is smaller than the range set in the "SW limit switch noise suppression window" parameter.

– Check the positions of the software limit switch.

or

– Adjust the width of the noise suppression window.
