Setting range: 25-100%
Factory set: 100%
Output voltage adjustment coefficient adjusts output voltage of inverter to meet different V/F requirement.

Torque improve:
Improve low frequency torque trait by voltage compensation. Please set it rightly. If too high, motor
maybe happens over excitation at low frequency running, over heat while long time, even over current protection or can
not start normally.
Note: while [F8.00] is 1, [F8.12] is invalid.
Torque improve close frequency:
Set torque improve valid range. While output frequency is over this value, torque
improving function stops. 100% is corresponding to motor rated frequency.
