When the frequency source selects PID, i.e. F0-03 or F0-04=8, this group of function is
enabled. (Please refer to F0-03 and F0-04).
This parameter decides the target quantity reference channel of the process PID.
The setup target quantity of the process PID is relative value, and the setup 100% is relative to
the 100% of feedback signal of the controlled system.
The PID range (FA-04) is not essential because the system will always calculate according
to the relative value (0 to 100%) no matter how the range is set. However, if PID range is set,
it can view the actual values relative to the reference and feedback of PID via the display
parameters on the keyboard.
FA-01
PID keyboard reference Factory default value 50.0%
Setup range 0.0% to 100.0%
When FA-00=0 is selected, the target source is keyboard reference. It needs to set this
parameter. The benchmark value of this parameter is system feedback quantity.
