1) External connection
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) (2) Feedback value
Frequency setting mode selection ／ PID control feedback control signal 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
:Deviation input (no feedback input)
:VI/II (voltage/current input)
:RR/S4 (potentiometer/voltage input)
:RX (voltage input)
:Optional AI1 (differential current input)
:Optional AI2 (voltage/current input)
: PG feedback option
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
If the feedback input is RR/S4 terminal: Function number 144,145
If the feedback input is VI/II terminal : Function number 146,147
If the feedback input is RX terminal : Function number 148,149
