Detailed instruction of parameters
output current of the VFD and K is the motor
protection coefficient.
The smaller K is, the greater M is, and the more
likely protection is implemented.
When M=116%, protection is performed after
motor overload lasts for 1 hour; when M=150%,
protection is performed after motor overload lasts
for 12 minutes; when M=180%, protection is
performed after motor overload lasts for 5
minutes; when M=200%, protection is performed
after motor overload lasts for 60 seconds; and
when M ≥ 400%, protection is performed
immediately.

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
