BacklashIirFilter Parameter

Default Value: 0

Minimum Value: 0

Maximum Value: None

Units: time milliseconds

Type: int

The BacklashIirFilter parameter smooths sudden changes in the position command that are caused by backlash compensation. This parameter specifies the time constant of a first-order, low-pass Infinite Impulse Response (IIR) filter that is applied to the backlash compensation component of motion. The value of this parameter corresponds approximately to the time interval over which an impulse, which is a sudden change, occurs in backlash compensation.

A value of zero for the BacklashIirFilter deactivates the filtering. A larger value causes more filtering and lower accelerations.
