(1) The proportional band (P), integral time (I), and derivative time (D) for performing
PID operation in normal control mode are set.
(2) For thermocouple input, set the proportional band (P) with temperature. For
micro voltage, voltage and current, set with % for full-scale.
(3) Set the proportional band (P), integral time (I), and derivative time (D) within the
following ranges.
(a) For PI control, set the derivative time to 0.
(b) For P control, set the derivative time and the integral time to 0.
