Torque control under Real sensorless vector control and vector control
● Under variable speed limiter control with Pr. 800="6 or 106", the process to adjust the speed
command value to the actual speed is not performed, and thus the torque limit remains valid.
This prevents torque from suddenly changing at a speed change.

Fig. 5-56:
NOTE When Pr. 800 = "6 or 106" (torque control by a variable-current limiter), Pr. 690 "Deceleration check
time" and Pr. 873 "Speed limit" are ignored.
