Cooling fan
control
0~1 【 0 】
0: Auto stop mode: The fan keeps working when
the inverter is running. When the inverter stops,
whether the fan work s or not depends on the
module temperature of inverter.
1: The fan keeps working when powering on.

0~2 【 0 】
0 ： PWM as 1 ， Noise in lower frequency is low,
Noise in higher frequency is high
1 ： PWM as 2 ， noise is so lower when motor
working under this mode ， but temperature rise
is high ， select the small KW frequency inverter
use
2 ： PWM as 3 ， noise is so high when motor
working under this mode ， Be more effective to
restrain the oscillation

Control
PID control is a common used method in process
control, such as flow, pressure and temperature
control . The principle is firstly to detect the bias
between preset value and feedback value, then
calculate output frequency of inverter according to
proportional gain, integral and differential time.
