10.3 Setting Limiter to Control Output
Description
Control output high and low limits can be set to restrict the control output to the operation
range between those limits.
The output limiter is prepared for each PID group, and works according to the selected
PID group.
This, however, excludes preset output in RESET mode.

Note1: The PID number (1 to 8, R) is displayed on Group display while each parameter is displayed.
Note2: When the setting is low limit ≥high limit, the controller operates as low limit = high limit -1 digit.
