Modify
selection of motor 1 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, and 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=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.
