Overload protection
coefficient of motor
1
Motor overload multiples M=Iout/(In*K)
In is rated motor current, lout is VFD output
current, and 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.
