Torque Offset Setting
Control Mode SVC FOCPG FOCPM Default: 0.0
Settings 0.0–100.0% (motor drive rated torque)
 Sets the torque offset. The motor rated torque is 100%.

High Torque Offset
Control Mode SVC FOCPG FOCPM Default: 30.0
Settings 0.0–100.0% (motor drive rated torque)

Middle Torque Offset
Control Mode SVC FOCPG FOCPM Default: 20.0
Settings 0.0–100.0% (motor drive rated torque)

Low Torque Offset
Control Mode SVC FOCPG FOCPM Default: 10.0
Settings 0.0–100.0% (motor drive rated torque)
 When set to 3, the torque offset sources are Pr.07-21, Pr.07-22 and Pr.07-23 according to the
multi-function input terminal settings (31, 32 or 33). The motor rated torque is 100%.

Reverse Regenerative Torque Limit
Control Mode FOCPG FOCPM Default: 200
Settings 0–300% (rated torque of the motor drive)
 The motor rated torque is 100%. The settings for Pr.07-24–Pr.07-27 compare with Pr.03-00=5, 6, 7, 8. The
minimum of the comparison result is torque limit. The diagram below illustrates the torque limit.
