compensation)
2: Frequency-variable motor (without low-speed
compensation)
Motor overload multiples M=Iout/(In*K)
In is rated motor current, lout is VFD output
current,
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=150%,
protection is performed after motor overload
lasts for 12 minutes; when M=200%, protection
is performed after motor overload lasts for 1
minute; and when M≥400%, protection is
performed immediately.
