Error 27 Encoder system
Error: 27.01 (1B01hex | 6913dec) Description: Relative position value invalid | ||
|---|---|---|
|
| |
Cause | Measure | |
Error 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. | |
Error: 27.02 (1B02hex | 6914dec) Description: Relative speed value invalid | ||
|---|---|---|
|
| |
Cause | Measure | |
Error 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. | |
Error: 27.04 (1B04hex | 6916dec) Description: Failed to start referencing | ||
|---|---|---|
|
| |
Cause | Measure | |
Encoder system not ready. | – Repeat referencing. – If the fault occurs repeatedly, contact SEW- EURODRIVE Service. | |
Error: 27.05 (1B05hex | 6917dec) Description: Referencing not completed successfully | ||
|---|---|---|
|
| |
Cause | Measure | |
Encoder system not ready. | – Repeat referencing. – If the fault occurs repeatedly, contact SEW- EURODRIVE Service. | |
Error: 27.06 (1B06hex | 6918dec) Description: Encoder process values invalid | ||
|---|---|---|
|
| |
Cause | Measure | |
Error 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. | |
Error: 27.07 (1B07hex | 6919dec) Description: Discrepancy error absolute position | ||
|---|---|---|
|
| |
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. | |
Error: 27.08 (1B08hex | 6920dec) Description: Cross-checking error speed calculation | ||
|---|---|---|
|
| |
Cause | Measure | |
Encoders involved in speed calculation signaled different speed values. | – Check the tolerance parameters. – Check the configuration of the drive train. – Check the system. | |
Error: 27.09 (1B09hex | 6921dec) Description: Discrepancy error relative position | ||
|---|---|---|
|
| |
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. | |
Error: 27.10 (1B0Ahex | 6922dec) Description: Internal error | ||
|---|---|---|
|
| |
Cause | Measure | |
Encoder signaled internal fault. | – Check the wiring. – Check interference sources (light beam interrupted, reflector, signal cables, etc.). – Replace the encoder.
Note that in the manual mode "emergency mode", you can move the drive using the motor encoder even if the external position encoder is faulty. | |
