Position loop, velocity loop, speed detection filter and torque command filter have their 2
pairs of gain or time constant (1st and 2nd).
For details of switching the 1st and the 2nd gain or the time constant, refer to P.5-17 "Gain
Switching Function" of Adjustment.
The function and the content of each parameter is as same as that of the 1st gain and time
constant.

Set the time constant of 1st delay filter which affects the input of velocity feed forward.
<Usage example of velocity feed forward>
The velocity feed forward will become effective as the velocity feed forward gain is gradually
increased with the velocity feed forward filter set at approx. 50 (0.5 ms). The positional
deviation during operation at a constant velocity is reduced as shown in the equation below
in 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 [%]) / 100
