Fault 21 Digital motor integration 1

Subfault: 21.1

Description: Communication error

 

Response: Output stage inhibit

Cause

Measure

Communication error at interface of digital motor integration.

Check the cabling.

Subfault: 21.2

Description: Slave required

 

Response: Digital motor integration

Cause

Measure

Device started up with a drive with digital motor integration but no drive with digital motor integration is connected.

– Check the connection of the digital motor integration.

– Perform startup again.

Subfault: 21.3

Description: Incompatible drive

 

Response: Output stage inhibit

Cause

Measure

The connected drive does not match the drive that was started up.

– Connect an appropriate drive.

– Perform startup again.

Subfault: 21.4

Description: Invalid label

 

Response: Output stage inhibit

Cause

Measure

The connected drive contains invalid data.

Replace the drive.

Subfault: 21.5

Description: Incompatible slave

 

Response: Output stage inhibit

Cause

Measure

The firmware versions of the slaves used are not compatible with one another.

Update the inverter and/or the slave.

Subfault: 21.6

Description: Overload/short circuit on the interface

 

Response: Output stage inhibit

Cause

Measure

There is a short circuit in the cabling of the digital motor integration's slave.

Check the cabling of the slave.

The voltage of the digital motor integration slave is too low.

Check the permitted cable length.

Subfault: 21.7

Description: High current demand of slave

 

Response: Output stage inhibit

Cause

Measure

The current consumption of the slave is too high.

Use a slave with lower current consumption.

Subfault: 21.8

Description: Parameter error

 

Response: Output stage inhibit

Cause

Measure

Error while processing data from digital motor integration slave.

Repeat the process in configuration state.

The connected drive contains invalid data.

Replace the drive.

Subfault: 21.9

Description: Illegal hot plug

 

Response: Emergency stop + output stage inhibit

Cause

Measure

A slave of digital motor integration was connected while the drive was enabled.

– Activate the configuration state of the inverter, e.g., by locking the output stage.

– Power cycle the inverter.

– Connect the slave while depowered.

A slave of digital motor integration was connected while the inverter was in standby mode without switching off the encoder supply.

– Switch off the encoder supply in standby operation.

– Connect the slave while depowered.

Subfault: 21.10

Description: Connection type not configured correctly

 

Response: Output stage inhibit

Cause

Measure

The connection type of the connected drive cannot be determined.

Set the connection type on the drive correctly.

Subfault: 21.11

Description: Illegal subslave

 

Response: Output stage inhibit

Cause

Measure

The device cannot be operated with a subslave connected via digital motor integration.

Connect another subslave.

Subfault: 21.12

Description: Slave/subslave not accessible – fault

 

Response: Emergency stop + output stage inhibit

Cause

Measure

A slave/subslave of digital motor integration is in the Device Update Manager.

Update the firmware of the slave/subslave.

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

Subfault: 21.13

Description: Slave/subslave not accessible – warning

 

Response: Warning

Cause

Measure

A slave/subslave of digital motor integration is in the Device Update Manager.

Update the firmware of the slave/subslave.

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

Subfault: 21.14

Description: Missing startup of brake control

 

Response: Output stage inhibit

Cause

Measure

Brake control not taken into operation.

Take brake control into operation or connect another drive.

Subfault: 21.20

Description: Slave – critical fault

 

Response: Output stage inhibit

Cause

Measure

A slave of digital motor integration detected a critical fault.

Pay attention to the error message of the subslave. Obtain the exact cause from this error message and take the appropriate fault elimination measures.

Subfault: 21.21

Description: Slave – fault

 

Response: Emergency stop + output stage inhibit

Cause

Measure

A slave of digital motor integration detected a fault.

Pay attention to the error message of the subslave. Obtain the exact cause from this error message and take the appropriate fault elimination measures.

Subfault: 21.22

Description: Slave – warning

 

Response: Warning

Cause

Measure

A slave of digital motor integration issued a warning.

Pay attention to the warning of the subslave. Obtain the exact cause from this warning and take the appropriate remedy measures.
