Setup Item
• Loop number
You can enter the setting for each loop. When changing these settings, select a loop
to be changed from 1 to 6 (default is 1). Only the number of loops specified at the
time of purchase appear in the list.
• Target Setpoint Tracking
Select whether to turn the Target Setpoint Tracking function ON (default) or OFF.
Operation proceeds as follows when turned ON.
• With no program control
Tracking when switching from remote to local (the local setting value follows the
remote setting value).
• During program control
Tracking when switching from program control to local control (the local setting
value follows the program setting value).
• Measured Value Tracking
Select whether to turn the Measured Value Tracking function ON (default) or OFF.
Operation proceeds in the following cases when the function is turned ON. Operates
only with local operation during program control.
• When shifting from manual operation to automatic operation.
• When starting automatic operation from the operation stop condition.
• When turning the power ON.
• When changing the target setpoint number
• Target Setpoint Lower and Upper Limit
Set when applying limits to the target setpoint setting range. The setting range is “EU
0.0% to 100.0% of the measurement span” (lower limit < upper limit). The available
setting range appears in the pop-up window.
• Output Velocity Limiter
You can turn the velocity limiter of the control output ON or OFF (default), and set the
rate of change in the range from 0.1% to 100.0%/s.
• Anti-Reset Windup
Select whether to activate the anti-reset windup function on Auto or Manual. If you
select Manual, select the deviation width of the point at which the PID computation is
resumed disengaging from the output saturated status, and the deviation width of
points that restart PID computation in the range from 50.0% to 200.0%.
