Torque Detection Filter Function (Pr. 827, Pr. 837); Model Speed Control Gain (Pr. 828); Torque Biases (Pr. 840 To Pr. 848); Torque Bias Function (Pr. 840 To Pr. 848) - Mitsubishi Electric FR-V500 Instruction Manual

3.32.9 Torque detection filter function (Pr. 827, Pr. 837
Set the time constant of the primary delay filter relative to the torque feedback signal.
Since the current loop response declines, use it with the factory setting.
