Motor overload

selection
0: No protection
1: Common motor
(with low speed compensation). 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: Frequency conversion motor (without low speed
compensation). Because the heat-releasing 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.

P02.27
Motor overload
protection
coefficient
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 reported after 1 minute, when
M>=400%, the fault will be reported instantly.
Setting range: 20.0%~120.0%

Correct the power displaying of motor. Only impact the displaying
value other than the control performance of the inverter.

The parameters P03.00~P03.05 only apply to vector control
mode. Below the switching frequency 1 (P03.02), the speed
loop PI parameters are: P03.00 and P03.01. Above the
switching frequency 2 (P03.05), the speed loop PI
parameters are: P03.03 and P03.04. PI parameters are
gained according to the linear change of two groups of
parameters. It is shown as below:
