PID Gains

PID Calculator

Tdo & Te required (2.0 & 0.33s defaults) Adjust Kg to achieve desired response

Good generic values: PID = 80,20,10 then adj Kg as needed

Tdo from Generator Data Sheet

Te ranges from 0.06s to 0.26s see Table 9

PID Gains

var / PF Integral and Loop Gain Settings

Use factory defaults as a staring point Increase Kg to increase speed of response (suggest

keeping it slow)

Increase Ki if var/PF regulation not acceptable

Protection

Shutdown Override (Enable to override shutdowns, Disabled is

default value) Function not affected:

Gen. Overvoltage

Gen. Undervoltage

Reverse VAR Fault Reset too long

Cannot be saved in EEPROM Cycling power causesfunction to become disabled on power up
