 The feed forward can reduce position-tracking error in the position control mode. Under any
frequency command pulse the position-tracking error always becomes zero if the parameter
setting value is 100.
 Increasing the parameter value enhance the response of position control. It is easy to cause
the system to be unstable, oscillation if the parameter value is too large.
