0: No protection
1: Regular motor (with low speed compensation)
2: Inverter motor (w/o low speed compensation)
Motor overload multiple M= Iout/(In*K)
In is rated motor current, lout is output current of
the inverter, and K is motor overload protection
coefficient.
The smaller the value of K, the larger the value of
M and the easier the protection.
When M=116%, protect when motor overload
lasts for 1 hour; when M=150%, protect when
motor overload lasts for 12 minutes; when
M=180%, protect when motor overload lasts for 5
minutes; when M=200%, protect when motor
overload lasts for 60 seconds; when M≥ 400%,
protect immediately.
