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.
M=116%: Protection will be applied when the motor
overloads for 1h;
M=150%: Protection will be applied when the motor
overloads for 12min;
M=180%: Protection will be applied when the motor
overloads for 5min;
M>=400%: Protection will be applied immediately.
