Description
AP.01 App Mode
Set the code to 2 (Proc PID) to select functions for the process PID.
AP.16 PID Output
Displays the existing output value of the PID controller. The unit, gain, and scale
that were set at AP. 42-44 are applied on the display.
AP.17 PID Ref Value
Displays the existing reference value set for the PID controller. The unit, gain,
and scale that were set at AP. 42-44 are applied on the display.
AP.18 PID Fdb Value
Displays the input value of the PID controller that is included in the latest
feedback. The unit, gain, and scale that were set at AP. 42-44 are applied on the
display.
AP.19 PID Ref Set
When AP.20 (PID control reference source) is set to 0 (Keypad), the reference
value can be entered. If the reference source is set to any other value, the
setting values for AP.19 are void.
AP.20 PID Ref Source
Selects the reference input for the PID control. If the V1 terminal is set to PID
feedback source (PID F/B Source), the V1 terminal cannot be set to the PID
reference source (PID Ref Source). To set V1 as a reference source, change the
feedback source.

TI Pulse input terminal (0-32kHz Pulse input)
When using the keypad, the PID reference setting can be displayed at AP.17.
When using the LDC keypad, the PID reference setting can be monitored from
AP.21 PID F/B Source
Selects feedback input for PID control. Items can be selected as reference input,
except the keypad input (Keypad-1 and Keypad-2). Feedback cannot be set to
an input item that is identical to the item selected as the reference. For
example, when Ap.20 (Ref Source) is set to 1 (V1), for AP. 21 (PID F/B Source), an
input other than the V1 terminal must be selected. When using the LCD
keypad, the volume of feedback can be monitored using a code from the
config mode (CNF) -06-08, by setting it to 18 (PID Fbk Value).
AP.22 PID P-Gain,
AP.26 P Gain Scale
Sets the output ratio for differences (errors) between reference and feedback. If
the Pgain is set to 50%, then 50% of the error is output. The setting range for
Pgain is 0.0-1,000%. For ratios below 0.1%, use AP.26 (P Gain Scale).
