Fault 27 Encoder system
Fault: 27.1 (1B01hex | 6913dec) Description: Relative position value invalid | ||
|---|---|---|
| Response: FS – encoder fault | |
Cause | Measure | |
Fault during diagnostics of encoder involved in calculating the position process value. | Check the exact fault in the fault memory and follow the instructions to remedy the fault. | |
Fault: 27.2 (1B02hex | 6914dec) Description: Relative speed value invalid | ||
|---|---|---|
| Response: FS – encoder fault | |
Cause | Measure | |
Fault during diagnostics of encoder involved in calculating the speed process value. | Check the exact fault in the fault memory and follow the instructions to remedy the fault. | |
Fault: 27.4 (1B04hex | 6916dec) Description: Failed to start referencing | ||
|---|---|---|
| Response: FS – warning | |
Cause | Measure | |
Encoder system not ready. | – Repeat referencing. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service. | |
Fault: 27.5 (1B05hex | 6917dec) Description: Referencing not completed successfully | ||
|---|---|---|
| Response: FS – warning | |
Cause | Measure | |
Encoder system not ready. | – Repeat referencing. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service. | |
Fault: 27.6 (1B06hex | 6918dec) Description: Encoder process values invalid | ||
|---|---|---|
| Response: FS – encoder fault | |
Cause | Measure | |
Fault during diagnostics of encoder involved in calculating a process value. | Check the exact fault in the fault memory and follow the instructions to remedy the fault. | |
Fault: 27.7 (1B07hex | 6919dec) Description: Discrepancy fault absolute position | ||
|---|---|---|
| Response: FS – warning | |
Cause | Measure | |
Encoders involved in position calculation signal different absolute position values. | – Check the tolerance parameters. – Check the configuration of the drive train. – Check the system. | |
Fault: 27.8 (1B08hex | 6920dec) Description: Cross-checking fault speed calculation | ||
|---|---|---|
| Response: FS – warning | |
Cause | Measure | |
Encoders involved in speed calculation have signaled different speed values. | – Check the tolerance parameters. – Check the configuration of the drive train. – Check the system. | |
Fault: 27.9 (1B09hex | 6921dec) Description: Discrepancy fault relative position | ||
|---|---|---|
| Response: FS – warning | |
Cause | Measure | |
Encoders involved in position calculation signal different relative position values. | – Check the tolerance parameters. – Check the configuration of the drive train. – Check the system. | |
