FOCPG and FOC Sensorless mode:
The motor rated current = 100%. The settings for Pr.11-17–Pr.11-20 compare with the Pr.03-00=7, 8, 9, 10. The
minimum value of the comparison result is the torque limit. The diagram below illustrates the torque limit.
TQCPG and TQC sensorless mode:
The function of Pr.11-17–11-20 is the same as FOC; however, in this case, the torque limit and the torque
command executes the output torque limit at the same time. Therefore, the minimum value between Pr.11-17–11-
20 and Pr.06-12 becomes the current output torque limit.
