■ Wait Operation
During a segment transition, wait operation brings the transition to be next segment into a wait (standby) state,
using the wait zone, until the deviation is canceled. The wait zone is a span of deviation that determines to what
degree a PV input is tracked.
Wait operation is available only at a segment junction that transfers from ramp to soak.

The controller (UP150)
can move to the next

During the “wait”, the timer for the program pattern progress stops, so that time event (EVn) is held. (RUN lamp

The PV event does not stop even if the controller is in the “wait”.
