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.
The smaller the K, the larger the value of M, the
easier the protection.
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=180%, protection is performed
after motor overload lasts for 5 minutes; when
M=200%, protection is performed after motor
overload lasts for 60 seconds; and when M≥ 400%,
protection is performed immediately.
