The positionaldeviation during operation at a constant velocity is reduced as shown in the equation belowin proportion to the value of velocity feed forward gain.Positional deviation [unit of command] = command speed [unit of command/s] /positional loop gain [1/s] × (100 - velocity feed forward gain [%]) / 1001.
