speed running.

Overload
protection
coefficient of
motor 1
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, and 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.
