Description
0.01–655.35mH
0.01–655.35mH
0–10000V
0–0xFFFF
0%–50% (of the rated current of the motor)
0: No protection
1: Common motor (with low-speed compensation)
2: Frequency-variable motor (without low-speed
compensation)
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.
if M is 116%, protection will be applied when motor
overloads for 1h; if M is 200%, protection will be
applied when motor overloads for 60s; if M is no
less than 400%, protection will be applied
immediately.
