Overload
protection of
motor 1
0: No protection
1:
Common
motor
(with
low-speed
compensation). As the cooling effect of common
motor will be degraded in low speed, the
corresponding electronic thermal protection value
should also be adjusted properly, the low
compensation here means to lower the overload
protection threshold of the motor whose running
frequency is below 30Hz.
2: Frequency-variable motor (without low speed
compensation).
As
the
cooling
effect
of
frequency-variable motor is not affected by the
rotating speed, there is no need to adjust the
protection value during low speed running.

Overload
protection
coefficient of
motor 1
Motor overload multiples M=Iout/(In×K)
In is rated motor current, lout is inverter output
current, K is motor overload protection coefficient.
The smaller the K, the larger the value of M, and
the easier the protection.
M=116%: protection will be applied when motor
overloads for 1h; M=200%: protection will be
applied when motor overloads for 60s; M>=400%:
protection will be applied immediately.
