 The base for Pr.10.12 is Pr.01.00. When the PID feedback control is enabled, and (PID set point
source – feedback) is larger than Pr.10.12, and the time exceeds the Pr.10.13 setting, then the
multi-function output terminal #16 (PID Feedback Error) displays as a warning and acts
according to Pr.10.20 settings.
 When you set Pr.10.12 to 0, the PID feedback error detection function is disabled.
