Fault 12 Brake

Subfault: 12.1

Description: Brake output fault

 

Response: Application stop + output stage inhibit

Cause

Measure

No brake connected.

– Check the brake connection.

– Check the startup.

Brake cable disconnected in switched-on state.

Check the connection of the brake.

The brake was overloaded by an overcurrent > 2 A.

– Make sure that the connected brake is permitted.

– Check the brake.

The brake was overloaded by frequent connection (> 0.5 Hz).

Reduce the switching frequency of the brake.

Subfault: 12.2

Description: DC 24 V brake voltage not within permitted tolerance range

 

Response: Application stop + output stage inhibit

Cause

Measure

DC 24 V supply voltage not within permitted tolerance of 24 to 26.4 V.

Check the DC 24 V supply voltage.

Subfault: 12.3

Description: Brake temperature not within permitted range

 

Response: Output stage inhibit

Cause

Measure

Brake temperature not within permitted range (too low or too high).

Check the ambient conditions and the application.

In the case of decentralized devices, the overvoltage of the DC link is dissipated via the brake. As a result, the temperature of the brake is too high.

Check the application for how often generator mode occurs.

Subfault: 12.4

Description: Brake control module missing

 

Response: Output stage inhibit

Cause

Measure

Brake control has been activated although the device is not equipped with the matching module.

Select a different brake type or brake connection.

Subfault: 12.5

Description: Short circuit on the brake

 

Response: Output stage inhibit

Cause

Measure

Short circuit in the brake.

Check the brake connection.

Subfault: 12.7

Description: Overcurrent in the brake

 

Response: Output stage inhibit

Cause

Measure

The brake requires more current than the brake control electronics can supply.

– Check the parameterization of the brake.

– Use suitable brake/brake control electronics.

Brake coil defective.

Replace the brake.

Subfault: 12.8

Description: Supply voltage fault

 

Response: Brake supply voltage fault

Cause

Measure

The fault can be caused as follows:

– The supply voltage of the brake rectifier is outside the valid range.

– The supply voltage of the brake rectifier is not available.

– Check the supply voltage.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 12.9

Description: Plausibility error

 

Response: Output stage inhibit

Cause

Measure

No brake connected.

Connect a brake.

Brake connected incorrectly.

Check and correct the brake connection.

Wrong brake was started up.

Check the startup.

Subfault: 12.20

Description: Digital motor integration – critical fault

 

Response: Output stage inhibit with self-reset

Cause

Measure

The intelligent brake rectifier of digital motor integration has detected a critical fault.

Observe the fault message of the subslave. Identify the exact cause of this fault message and take the appropriate measures to eliminate the fault.

Subfault: 12.21

Description: Digital motor integration – fault

 

Response: Emergency stop + output stage inhibit with self-reset

Cause

Measure

The intelligent brake rectifier of digital motor integration has detected a fault.

Observe the fault message of the subslave. Identify the exact cause of this fault message and take the appropriate measures to eliminate the fault.

Subfault: 12.22

Description: Digital motor integration – warning

 

Response: Warning with self-reset

Cause

Measure

The intelligent brake rectifier of digital motor integration signaled a warning.

Observe the warning of the subslave. Identify the exact cause of this warning and take the appropriate measures for elimination.

Subfault: 12.23

Description: Digital motor integration – timeout

 

Response: Output stage inhibit

Cause

Measure

Communication with intelligent brake rectifier disrupted.

Check the connection.

Subfault: 12.24

Description: Digital motor integration – initialization error

 

Response: Output stage inhibit

Cause

Measure

Initialization of intelligent brake rectifier failed.

– Acknowledge the fault.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.
