properly, the low compensation here means to lower
the overload protection threshold of the motor whose
running frequency is below 30Hz.
2: Frequency-variable motor (without low speed
compensation).
As
the
cooling
effect
of
frequency-variable motor is not affected by the
rotating speed, there is no need to adjust the
protection value during low speed running.

Overload
protection
coefficient of
motor 1
Motor overload multiples M=Iout/(In
×K)
In is rated motor current, lout is inverter output
current, K is motor overload protection coefficient.
The smaller the K, the larger the value of M, and the
easier the protection.
M=116%: protection will be applied when motor
overloads for 1h; M=200%: protection will be applied
when motor overloads for 60s; M>=400%: protection
will be applied immediately.

This function adjusts the power display value of
motor 1 only, and it does not affect the control
performance of the inverter.
