Material number:

Backlash compensation provides spindle pitch and backlash compensation for B&R ACOPOS servo drives. A license is required to use this function with the ACOPOS P3.

Typical applications:
  • Spindle drives
  • High-precision positioning drives with gearbox
  • Robotics applications
Functional scope:

The positioning precision of spindle drives with and without backlash is increased through compensation without requiring an extra encoder on the load side. Control quality can also be significantly improved in other applications with systematic encoder errors and/or mechanical play using pitch and backlash compensation (PBC).
Compared to conventional handling of mechanical play in the setpoint generator, spindle pitch and backlash compensation provides substantial benefits. With condition-based closed-loop control, backlash that occurs on a changing edge is overcome quickly and reliably, and the transition to the new edge is as smooth as possible.
