Fault 26 External fault

Subfault: 26.1

Description: Terminal

 

Response: External fault

Cause

Measure

Fault message about external fault source.

Programmable via 8622.5 (default: application stop (with output stage inhibit)).

Subfault: 26.2

Description: Emergency shutdown

 

Response: Output stage inhibit + open line contactor + module bus response "Critical"

Cause

Measure

Another module bus station requested external emergency shutdown.

Check other module bus stations for faults.

Subfault: 26.3

Description: Power section emergency shutdown

 

Response: Output stage inhibit + line contactor unchanged + module bus response "Critical"

Cause

Measure

Power section requested external emergency shutdown because it detected a critical fault.

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 regenerative operation energy arises.
