This function parameter restricts output torque of the AC drive in speed control. The
torque limits are dened by F2-09 to F2-12.
When F2-11 is set to 0, the motoring state and regenerative state are not distinguished.
The torque limit is dened by F2-10.
When F2-11 is set to 1 to 8, the motoring state and regenerative state are distinguished.
In motoring state, full range of torque limit is set by F2-010. In regenerative state, full
range of torque limit is set by F2-12.

dependent
In applications such as cam, quick acceleration/deceleration and sudden unloading
without using braking resistor, reduce bus voltage overshoot during motor braking so as
to prevent occurrence of overvoltage.
F2-23 is a percentage of rated motor power. If overvoltage still occurs after you set F2-22
= 1 , decrease setting of F2-23.
