Error message

E170 Pos. error too large %.2s

Cause of error

- Parameter value in MP640.x is too small
- Defect in the mounting of the position encoder
- Incorrect thermal, linear or nonlinear compensation
- Excessive backlash

Error correction

- Check the parameter value in MP640.x (maximum position deviation between MC and CC during operation)
- Check the parameter value in MP720.x (linear axis error compensation for analog axes)
- Check the parameter value in MP710.x (backlash compensation)
- Check the mounting of the position encoder
- Inform your service agency
