protection Because the heat-releasing effect of the common
motors will be weakened, the corresponding electric
heat 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: 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.
Times of motor overload M = Iout/(In*K)
In is the rated current of the motor, Iout is the output
current of the inverter and K is the motor protection
coefficient.
So, the bigger the value of K is, the smaller the value
of M is. When M =116%, the fault will be reported
after 1 hour, when M =200%, the fault will be
Motor 1
reported after 1 minute, when M>=400%, the fault
overload
will be reported instantly.
