F9 Group: Pid Control - Craftsman G10-0R7G-2SB Manual

0: Display two decimal points, the maximum frequency can be adjusted to 300.00Hz.
1: Display one decimal point, the maximum frequency can be adjusted to 3000.0Hz.
Code
F8.33
When the bus voltage is too high, on the basis of the current frequency automatic
rise F8.28 Settings, to stabilize the busbar voltage, reduce overvoltage faults occur.

6.10 F9 Group: PID 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. Please refer to following figure:
