FeedforwardGainJff Parameter

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 change in velocity as a function of time.. The units of this gain are N/(m/s³) or Nm/(rad/s³) when the FeedforwardGainNormalizationFactor Parameter is set correctly.
