6.6 Adjustment of real sensorless vector control, vector
control
6.6.1 Speed detection filter and torque detection filter
(Pr. 823, Pr. 827, Pr. 833, Pr. 837)
Set the time constant of the primary delay filter relative to the speed feedback signal and torque
feedback signal. Since this function reduces the speed loop response, use it with the initial
value.
This parameter can be set when the FR-A7AP (option) is mounted.
