Functions and Parameters for “Single-loop Control” in Initial State (Fac-
tory-set default)
Functions and parameters in initial state are given in the tables below. For details on each
parameter, refer to “6.2 Lists of Parameters.”

PV Input
PV input (INPUT1) is a universal input, which can receive signals from thermocouple, RTD,
or DC voltage signals. The controller is capable of biasing, square root extraction, first-
order lag computation (filtering), ten-segment linearizer approximation, and ten-segment
linearizer biasing on input signals.
Each function can be set by the following parameters.

Note: PV input bias (BS) and PV input filter (FL) among the operating parameters are used as bias and filter when normal
operation. Analog input bias (A.BS1) and analog input filter (A.FL1) among the setup parameters are used when PV
correction value is decided in advance.
