protection will be adjusted properly. The low speed
compensation characteristic mentioned here means
reducing the threshold of the overload protection of the
motor whose running frequency is below 30Hz.
2: Frequency conversion motor (without low speed
compensation) Because the heat-releasing effect of the
specific motors won't be impacted by the rotation speed,
it is not necessary to adjust the protection value during
low-speed running.
When P02.27=overload protection current of the
motor/rated current of the motor
So, the bigger the overload coefficient is, the shorter the
reporting time of the overload fault is. When the overload
coefficient <110%, there is no overload protection. When
the overload coefficient =116%, the fault will be reported
after 1 hour, when the overload coefficient=200%, the
fault will be reported after 1 minute.
Setting range: 20.0%~120.0%

Torque boost should be selected according to the load.
The larger the load is, the higher the torque is. Too high
torque boost will create excessive magnetizing current,
