Default
value
Modify
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.
