• The LBA detection time is automatically set by auto-tuning (except in
heating and cooling control).
• If the optimum LBA detection time cannot be obtained by auto-tun-
ing, set the time in the "LBA detection time" parameter (level 2
mode).
• Calculate the LBA detection time as follows:
(1) Set output to maximum.
(2) Measure the time it takes for the input change width to reach the
LBA detection width (default: 0.2 % full-scale).
(3) Take a value twice that of the measurement time as the LBA detec-
tion time.
Measurement time Tm
LBA detection time = Tm x 2
(4) In the case of ON/OFF operation, set the LBA detection time to a
value longer than the control period.
