Subfault: 26.3
Description: Power section emergency shutdown
Response: Output stage inhibit
Cause Measure
Power section requested external emergency
shutdown because it detected critical fault. Contact SEW‑EURODRIVE Service.
Subfault: 26.4
Description: External braking resistor fault
Response: Response to external braking resistor fault
Cause Measure
External braking resistor's temperature switch
connected to terminal tripped. – Check the resistor mounting position.
– Clean the resistor.
– Check the configuration of the resistor.
– Install a larger resistor.
– Check the trip switch settings.
– Optimize the travel cycle so that less regenera-
tive operation energy arises.
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 upstream of 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
downstream of 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 flush. Make sure that the reference cam and the hard-
ware limit switch are mounted flush.
