Speed control by real sensorless vector control, vector control Parameter
6 - 80
6.3.2 Torque limit level setting for speed control
(Pr. 22, Pr. 803, Pr. 810 to Pr. 817, Pr. 858, Pr. 868, Pr. 874)
This function limits the output torque to the predetermined value during speed control under real
sensorless vector control or vector control.
●
Set the torque limit level within the range 0 to 400% in Pr. 22. When the TL signal is turned
on, torque limit level 2 functions.
●
You can select whether the torque limit level is set using parameters or analog input teminals
(terminal 1, 4). In addition, you can set torque limit level for forward (power driving/
regeneration) and reverse (power driving/regeneration) operation individually.
NOTE
Under real sensorless vector control, the lower limit of torque limit level is set 30% if the
value less than 30% is input.
