Setting range: 0–2
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
compensation indicates lowering the
overload protection threshold of the
motor whose running frequency is
lower than 30Hz.
2: Variable-frequency motor
protection (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.
Specifies the motor overload
protection coefficient. A small motor
overload protection coefficient
indicates a great overload
multiplication (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=200%,
protection is performed after motor
overload lasts for 60 seconds; and
when M≥400%, protection is
performed immediately.
Setting range: 20.0%–150.0%
