• When "Bumpless at RUN" is enabled, an integral MV correction
(bumpless) is performed to prevent abrupt changes in the MV when
switching from stop to run.
• Even when the setting is disabled, the bumpless correction is
performed when PID values change (including changing the PID set)
and when AT ends or is stopped.
• This setting is used to select whether control is stopped or changed
to floating control when a potentiometer error occurs during closed
control in position proportional control.
