Step 10 – Setting PID Parameters; Proportional Gain (Bn-17) and Integral Time (Bn-18)

•After all external connections have been made and the protective covers have been replaced, power up the inverter but do not run at this point.

•Parameters Bn-17 = 1.0 (Proportional Gain) and Bn-18 = 10.0s (Integral Time) are factory set to the values shown. However, a good starting point for these values is setting the Proportional Gain Bn-17 = 2.0 and the Integral Time Bn-18 = 5.0s. To change these parameters, follow the keypad navigation procedure below.
