Description
automatically. In static
0.1–6553.5mH self-learning mode 2, the settings
of P02.06–P02.08
updated automatically. These
parameters are the basic
0.1–6553.5mH
parameters for the VFD to control
the motor and have direct impact
on control performance.
0.1–6553.5A
Note: Exercise caution before
modifying these parameters.
0: No protection
1: Common motor (with low speed compensation).
Because the heat-releasing effect of the common
motors will be weakened, the corresponding
electric heat protection will be adjusted properly.
The low speed compensation characteristic
mentioned here means reducing the threshold of
the overload protection of the motor whose
running frequency is below 30Hz.
2: Variable frequency motor (without low speed
compensation) Because the heat-releasing effect
of the specific motors won't be impacted by the
rotation speed, it is not necessary to adjust the
protection value during low-speed running.
Times of motor overload M = Iout/(In*K)
In is the rated current of the motor, Iout is the
output current of the VFD and K is the motor
protection coefficient.
So, the bigger the value of K is, the smaller the
value of M is. 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.
