FeedforwardGainJff Parameter

Default Value: 0.0

Minimum Value: 0.0

Maximum Value: None

Units: None

Type: float

Tip: To automatically tune and optimize an axis in a new or existing system, you can use the EasyTune feature. This feature is in the Axes > Servo section of the Configure workspace in Automation1 Studio. After EasyTune completes, the optimized servo gains and servo filters are committed to the controller.

HARDWARE: This parameter applies only when used with the GL4, the XL4s, or when you use it under Autofocus control with other drive types.

Use the FeedforwardGainJff parameter to set the jerk feedforward gain. This parameter adds a feedforward control effort in proportion with the rate of change of acceleration. The units of this gain are N/(m/s³) or Nm/(rad/s³) when the FeedforwardGainNormalizationFactor Parameter is set correctly.
