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.

Correct the power displaying of motor 1.
Only impact the displaying value other than the
control performance of the VFD.

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
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:
