8.7.21 Fault 28 FCB drive functions
Subfault: 28.1
Description: FCB 11/12 – Timeout while searching zero pulse
Response: Emergency stop + output stage inhibit
Cause Measure
Failed to find zero pulse of encoder's C track
within specified search time during reference
travel. Check the encoder wiring.
Subfault: 28.2
Description: FCB 11/12 – Hardware limit switch before reference cam
Response: Emergency stop + output stage inhibit
Cause Measure
The hardware limit switch was reached during ref-
erence travel. The reference cam was not detec-
ted. Make sure that the reference cam is not installed
behind the hardware limit switch.
Subfault: 28.3
Description: FCB 11/12 – Hardware limit switch and reference cam not flush
Response: Emergency stop + output stage inhibit
Cause Measure
Hardware limit switch and reference cam not
mounted properly. Make sure that reference cam and hardware limit
switch are installed so they overlap.
Subfault: 28.4
Description: FCB 11/12 – Reference offset error
Response: Emergency stop + output stage inhibit
Cause Measure
Error determining reference offset. – Make sure that the reference offset is not set to
a larger value than the "Modulo maximum" limit
value.
When using a single-turn absolute encoder, make
sure that the reference offset is not set to a larger
value than one encoder revolution.
Subfault: 28.5
Description: FCB 11/12 – Referencing not possible
Response: Emergency stop + output stage inhibit
Cause Measure
In the active drive train, the "Actual position
source" parameter is set to "No encoder". Assign "Actual position source", or do not perform
referencing.
