Backlash Compensation to Feedback Positions
Backlash compensation is also effective for feedback positions. This setting uses the axis
parameter [Backlash Setting].
To perform backlash compensation for feedback positions, the [Command Pulse Count Per
Motor Rotation] settings for command position and feedback position must be matched.
For the command position, refer to "Command Position Unit Setting" on page 5-29. For the
feedback position, refer to "Error Monitor Function Setting" on page 5-47.
You can also use [Feedback Pulse Input Backlash Enable] to enable/disable the backlash
compensation function only for feedback positions.
This is because there is a semi-closed loop method and a full-closed loop method for feedback.
Backlash compensation is enabled under the semi-closed loop method and disabled under the
full-closed loop method.
For [Feedback Pulse Input Backlash Enable], refer to "Feedback Pulse Input Setting" on page
5-43.
