PID control parameter unit
The first part of LED(form right to left)
：
Inner PID control
0
：
Inner PID control is invalid 1
：
Inner PID control is valid
2
：
Inner PID control is conditional valid. Inner PID is set by external terminals X1
～
X4 ( Parameters F3.0~F3.3) .

The fourth part of LED: The pole choosing of PID controller
0: Monopole PID control 1: ambipolar PID control
Under the monopole PID control mode, the output phase sequence of inverter is
mono-direction; and the external terminal decides the direction of output that it has
no relation with the output of PID controller. The adjusting effect of PID controller
