PID Control
3G3RX2-series is equipped with 4 independent PID functions, and each PID can be set independently.
Four PID functions can be used for motor control by switching the [PIO1]/[PIO2] terminals.
PID not used for motor control can be used for operation of exterior PID not related to inverter control
freely.
This helps to save space and cost because there is no need to install a separate PID controller.
PID1 can be controlled based on 3 deviations.
Connecting PID1 and PID2 can make 2-layer PID control possible.
For PID control, you can select feed-forward control to attempt stabilizing disturbance in advance, in
addition to feedback control to stabilize disturbance.
To control output frequency sent to the motor by the PID function, selection of PID1-4 and setting of fre-
quency command are required.
In the soft-start function, operating normally for a certain period of distance at the start can raise output
automatically and then shift to PID control. See
Sleep operation, which is more energy saving, can be set for when the flow rate or air volume is
increased. See
During PID operation, PID functions are disabled and normal output is performed with the command
selected as a target value, while the input terminal function [PID] signal is ON.
Multi-layer command by PID control command is feasible.
