Detailed instruction of parameters

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 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 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.
Setting range: 0.00~3.00
P03 Group Vector control
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
