PID scale
When PID Scale (A075) is set, the following parameters undergo scale conversion.
(Value after conversion) = (Value before conversion) × (A075)

A031
Feedback Selection
Select a terminal used for the feedback signal in PID feedback selection A076.
The target value depends on the terminal selected in frequency reference A001 other than that
in A076. Also note that when A001 is set to "01: Control circuit terminal block," the setting of
FV/FI Selection (A005) is disabled.
To specify "02: Modbus communication (Modbus-RTU)" for PID Feedback Selection (A076),
transfer the data as follows.
Write the data in holding register address 0006h based on 100% representing 10,000.

0006h
Note: You can read and write data. However, you can read data only when Modbus-RTU is selected for
the PID feedback.
Data cannot be read under other settings.
If "03: Pulse train input" is set for PID Feedback Selection (A076), the Inverter obtains a
percent conversion result (100% at maximum frequency) of the input pulse train frequency (Hz)
as a feedback value.
For details on pulse train input frequency, refer to "Pulse Train Frequency Input" on page 5-82.
Feedforward Selection
Select a terminal used for feedforward signals in PID Feedforward Selection A079.
The A079 setting is enabled even if the terminal selected in A079 is duplicated with the terminal
selected for target value or feedback value input.
If A079 is set to "disabled", feedforward control is disabled.
