Torque biases (Pr. 840 to Pr. 848)
PARAMETERS
3
3.32.9 Torque detection filter function (Pr. 827, Pr. 837 )
3.32.10 Model speed control gain (Pr. 828 )
3.33 Torque biases (Pr. 840 to Pr. 848)
3.33.1 Torque bias function (Pr. 840 to Pr. 848 )
Block diagram
z 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.
Parameter Name Factory Setting Setting Range Remarks
827
Torque detection filter 1
(when RT signal is off)
0s 0 to 0.1s
Extended mode
837
Torque detection filter 2
(when RT signal is on)
9999 0 to 0.1s, 9999
Parameter Name Factory Setting Setting Range Remarks
828 Model speed control gain 60% 0 to 1000% Extended mode
For details, refer to page 49.
z This function accelerates the rise of the torque at a start. Adjust the torque at a motor start using the contact
signals or analog signals .
