Motor overload
protection
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 1.
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
20.0
