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 | |
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. | |
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 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. | |
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 started up. | Start up brake control 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. | 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: 21.21 Description: Slave – fault | ||
|---|---|---|
| Response: Emergency stop + output stage inhibit | |
Cause | Measure | |
A slave of digital motor integration 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: 21.22 Description: Slave – warning | ||
|---|---|---|
| Response: Warning | |
Cause | Measure | |
A slave of digital motor integration issued a warning. | Observe the warning of the subslave. Identify the exact cause of this warning and take the appropriate measures for elimination. | |
