6.2.5 Group F04 Process PID Control
Closed-loop can be constituted not only by analogue reference and feedback but also by pulse
reference and feedback. Generally, the process PID control mode is used to regulate on-site
pressure, liquid level and temperature etc.
The maximum analogue input or maximum pulse input frequency (F16.17) corresponds to the
maximum output frequency (F00.06). The process PID control is shown in the following figure:

F16.
2: Terminal pulse reference. It is the value of the terminal pulse input reference, and maximum input
pulse frequency corresponding to 10V of the PID reference.

It defines the process PID regulator reference. When F04.01 = 0 (digital reference), it is enabled.
• When F00.04 = 3 (HD30-PIO function enable), the setting range is 0.00－24.00V.
• When F00.04 is set to other values (HD30-PIO function is disabled), the setting range is -10.00－
10.00V.

F04.04, F04.05 and F04.07 define the process PID parameters.
F04.06 defines the process PID integral upper limit.
F04.08 defines the process PID differential amplitude limit value.
F04.09 defines the sampling cycle of feedback value and the PID regulator calculates once in each
sampling cycle.
• When F04.07 = 0, the differential is disabled.
