avoiding overheating of the motor at low frequency running. Formula to automatically
torque rising as below for reference:
Voltage increasing= (P0.12/200) ×P0.09× (Inverter output current/rated current)
Calculation of manually torsion rising voltage is similar to the above, except deleting
the item ―Inverter output current/rated current‖, i.e. the proportion of inverter output
current and rated current. Choosing the torsion quantity shall be based on the loads,
improving torsion rising for bigger load, but rising extent shall not be excessive, or it
will lead to the motor over excitation running, efficiency falling and easy overheating.

Variation of loads sometimes can influence on the real rotation deviation of
motor. Through this function setting, the inverter will automatically adjust the
frequency output according to the loads situation. For example, running on
50Hz with rated current, the motor rev. must be less than synchronous rev. of
running at 50Hz. Here it can improve motor rev. by setting this parameter.
Note
：
Only when P0.00=1, this parameter is available.
