Motor overload multiples M=Iout/(In*K)
"In" is rated motor current, "Iout" is inverter
output
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=150%, protection is performed after motor
overload lasts for 12 minutes; when M=200%,
protection is performed after motor overload
lasts for 60 seconds; and when M≥400%,
protection is performed immediately.
