Overload protection
coefficient of
motor 2
Motor overload multiples M=Iout/(In*K)
In is rated motor current, lout is VFD output
current, K is motor overload protection
coefficient.
A smaller value of "K" indicates a bigger value of
"M".
When M=116%, protection is performed after
motor overload lasts for 1 hour; when M=200%,
protection is performed after motor overload
lasts for 60 seconds; and when M≥400%,
protection is performed immediately.
