Parameters Details
 Set the time constant for the low pass filter (LPF) after speed detection to one of 6 levels (0 to 5).
 Increasing the set value increases the time constant and decreases the noise generated by the
motor. Responsiveness, however, also decreases.
 Normally, use the default set value.
Default settings:
(1) Pn104 = 126 - For 200V drives of 1Kw or upper and 400V drives
(2) Pn104 = 84 - For 200V drives of less than 1 Kw
Set the time constant for the first-order lag filter inserted into the torque command.
 This parameter may be effective in suppressing vibration due to torsion resonance.
Default settings:
(1) Pn105 = 380 - For 200V drives of 1Kw or upper and 400V drives
(2) Pn105 = 570 - For 200V drives of less than 1 Kw
 Set the responsiveness of the position control system for the second position loop.
Default settings:
(1) Pn106 = 180 - For 200V drives of 1Kw or upper and 400V drives
(2) Pn106 = 270 - For 200V drives of less than 1 Kw
Set the responsiveness of the second speed loop.
 Set the second speed loop integration time constant.
 Set the second speed feedback filter.
