Fault 21 Digital motor integration 1

Error: 21.1 (1501hex | 5377dec)

Description: Communication error

 

Response: Output stage inhibit

Cause

Measure

Communication error at interface of digital motor integration.

Check the cabling.

Error: 21.2 (1502hex | 5378dec)

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.

Error: 21.3 (1503hex | 5379dec)

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.

Error: 21.4 (1504hex | 5380dec)

Description: Invalid label

 

Response: Output stage inhibit

Cause

Measure

The connected drive contains invalid data.

Replace the drive.

Error: 21.5 (1505hex | 5381dec)

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.

Error: 21.6 (1506hex | 5382dec)

Description: Overload/short circuit on the interface

 

Response: Output stage inhibit

Cause

Measure

Short circuit in the cabling of a slave of digital motor integration.

Check the cabling of the slave.

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

Check the permitted cable length.

Error: 21.7 (1507hex | 5383dec)

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.

Error: 21.8 (1508hex | 5384dec)

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.

Error: 21.9 (1509hex | 5385dec)

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 inhibiting the output stage.

– Switch the inverter off and on again.

– Connect the slave when it is de-energized.

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

– Switch off encoder supply in standby mode.

– Connect the slave when it is de-energized.

Error: 21.10 (150Ahex | 5386dec)

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.

Error: 21.11 (150Bhex | 5387dec)

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.

Error: 21.12 (150Chex | 5388dec)

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.

Error: 21.13 (150Dhex | 5389dec)

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.

Error: 21.14 (150Ehex | 5390dec)

Description: Missing startup of brake control

 

Response: Output stage inhibit

Cause

Measure

Brake control not started up.

Start up brake control or connect another drive.

Error: 21.20 (1514hex | 5396dec)

Description: Slave – critical fault

 

Response: Output stage inhibit

Cause

Measure

A slave 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.

Error: 21.21 (1515hex | 5397dec)

Description: Slave – fault

 

Response: Emergency stop + output stage inhibit

Cause

Measure

A slave 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.

Error: 21.22 (1516hex | 5398dec)

Description: Slave – warning

 

Response: Warning

Cause

Measure

A slave of digital motor integration has signaled a warning.

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