2) Types of PID control interface
Process value (frequency) and feedback value can be combined as follows for the PID control of the VF-PS1.
(1)Process value(frequency setting)
Frequency setting mode selection ／
:VI/II (voltage/current input)
:RR/S4 (potentiometer/voltage input)
:RX (voltage input)
:Operation panel input enabled (including LED/LCD
option input)
:2-wire RS485 communication input
:4-wire RS485 communication input
:Communication option input
:Optional AI1 (differential current input)
:Optional AI2 (voltage/current input)
:UP/DOWN frequency
:Optional RP pulse input
:Optional high-speed pulse input
Note 1: About the setting of and: Do not select the same terminal that is used feedback terminal.
Note 2: The voltage/current changeover of the analog input VI/II and the option AI1 can be set by the parameter
 or 
， 0:Voltage input (DC:0~10V)
1:current input (DC:4~20mA)
Note 3: The reaching signal of the feedback value and the process value can be output.
The desired feedback input should be assigned to the unoccupied output terminal.
The detection width for reaching can be set by the parameter 
