The motor output torque limit value can be set in four quadrants separately. During constant
power interval, when absolute value instruction mode set in d3-00 (torque command mode
selection), the output torque limit value decreases as the operation speed increases.
The four-quadrant torque limit value is set according to the percentage of the rated torque of the
motor, the setting range can be set to be up to 300%. When the motor power is consistent with
the frequency inverter power, the setting normally is not higher than 150%. The Max. value
U3-05 (Max. output torque of the motor) can be calculated when the power of inverter and
motor confirmed. When the four-quadrant torque limit value exceeds this effective value, the
inside of the algorithm will be limited to the maximum effective value.
When the motor is switched through the multi-function terminal (H0-XX = 31), the Max. output
torque effective value U3-05 of the activated motor will be recalculated. When the motor output
torque limit value is set to be greater than 150%, P0-03 (motor overload protection setting) and
P0-05 (over-torque protection action value setting) need to be adjusted, otherwise, oL2
(overload protection) or ot (over-torque protection) will be easily generated.

When the load is light, you can enable the function. The magnetic field can be automatically
adjusted to improve efficiency but the response performance of the speed control will reduce.
