User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
Fig. 7.126. View of Distance error warning
In determining the condition of the distance error, the internal calculation of the set value
is considered based on the user set point value and the measured value:
Sp
iner
= Fb+(Sp – Fb) * 0,5
where:
Sp
iner
– internal set point,
Fb
–feedback (measured value),
Sp
– set point value.
Autotuning, which is already under way, is a very sensitive process. Therefore, pay attention
to events that may interrupt the tuning of settings. These events include:
1)
Device power failure,
2)
Exceeding the time of autotuning (max 24h),
3)
Measurement error (e.g. sensor failure).
Autotuning is triggered every 30 seconds. During the autotuning process the possibility to
save the configuration is blocked (see
). In the case of several autotuning
processes taking place simultaneously, the save of new PID coefficients will be possible after
finishing the last autotuning process.
