4: PID target value
Common applications for PID control:
 Flow control: Use a flow sensor to feedback the flow data and perform accurate flow control.
 Pressure control: Use a pressure sensor to feedback the pressure data and perform precise
pressure control.
 Air volume control: Use an air volume sensor to feedback the air volume data to achieve
excellent air volume regulation.
 Temperature control: Use a thermocouple or thermistor to feedback temperature data for
comfortable temperature control.
 Speed control: Use a speed sensor or encoder to feedback motor shaft speed or input another
machine speed as a target value for closed loop speed control of the master-slave operation.
Pr.10-00 sets the PID set point source (target value).
PID control loop:
0: Digital keypad
1: RS-485 serial communication
2: External analog input (Refer to Pr. 03-00)
3: External UP/DOWN terminal
4: Pulse input without direction command (Pr. 10-16 without direction), use
with PG card
5: Pulse input with direction command (Pr. 10-16), use with PG card
6: CANopen communication card
8: Communication card (does not include CANopen card)
