Overload
protection
coefficient of
motor 2
Motor overload multiples M=Iout/(In*K)
“In” is rated motor current, “Iout” 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.
