0: No protection
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 speed
compensation indicates lowering the overload
protection threshold of the motor whose running
frequency is lower than 30Hz.
2: Variable-frequency motor compensation
(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.
Motor overload multiples M = Iout/(In*K)
In is rated motor current, Iout 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=150%,
protection is performed after motor overload lasts
for 12 minutes; 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.
