running frequency is below 30Hz.
2: Variable frequency 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.

coefficient
Times of motor overload M = Iout/(In*K)
In is the rated current of the motor, Iout is the
protection coefficient.
So, the bigger the value of K is, the smaller the
value of M is. When M=116%, protection is
performed after motor overload lasts for 1 hour;
when M=150%, protection is performed after
motor overload lasts for 12 minutes; when
M=180%, protection is performed after motor
overload lasts for 5 minutes; when M=200%,
protection is performed after motor overload lasts
for 60 seconds; and when
M≥ 400%, protection is
performed immediately.
