In speed control mode, if F2‑11 is set to 1 to 8, the torque upper limit is distinguished
between the motoring state and generating state. In motoring state, the full range of
torque upper limit is set through F2‑10. In generating state, the full range of torque
upper limit is set through F2‑12.

0.0% to 200.0% ‑
In applications such as cam, quick acceleration/deceleration and sudden unloading
without using a braking resistor, enable the power limit during generating to reduce
bus voltage overshoot during motor braking so as to prevent overvoltage. F2‑54
(power upper limit during generating) is a percentage to the rated motor power. If
overvoltage still occurs after power limit during generating is enabled, decrease F2‑
54.
