Overload
protection
selection of
motor 1
0: No protection
1: Common motor protection (with low-speed
compensation). As the cooling effect of a
common motor is degraded at low speed
running, the corresponding electronic thermal
protection value needs to be adjusted properly,
the low compensation indicates lowering the
overload protection threshold of the motor whose
running frequency is lower than 30Hz.
2: Variable-frequency motor protection (without
low speed compensation). Because the heat
dissipation function for a variable-frequency
motor is not impacted by the rotation speed, it is
not necessary to adjust the protection value at
low 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.
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=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.
