Error 26 External fault

Response: External fault

Cause

Measure

An error was triggered via a digital input or a bit of a control word.

– Eliminate the external fault.

or

– Change the response to an external fault under [Functions] > [Setpoints] > [Basic settings].

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

Cause

Measure

A module bus station requested external emergency shutdown.

Identify the error of the module bus station and eliminate it.

Response: Output stage inhibit + open line contactor + Module bus response "critical" + ESO

Cause

Measure

Power section detected critical error and requested external emergency shutdown.

Response: Response to external braking resistor error

Cause

Measure

The connected temperature switch of the external braking resistor has tripped.

– Check the mounting position of the braking resistor.

– Clean the braking resistor.

– Check the configuration of the braking resistor.

– Install a larger braking resistor.

– Check the external trip switch settings.

– Optimize the travel cycle so that less regenerative energy is created.

– Check the settings of the storage unit discharge function in the affected MOVIKIT® software module.

– Check plug-in connections.

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

Cause

Measure

Another module bus station has requested the external emergency shutdown with a "critical error category 2".

Check the other module bus station for errors.
