[Idle mode]
This chart shows that boards A, B, and C are set buffered in the unit, and then carried out.

When a board is carried out from the centering station, if the nex
t
board turns on the WAIT sensor on during deceleration of the
CENT motor, the C.OUT sensor turns off to immediately stop th
e
CENT motor, and acceleration starts again.
[Key operation]
In idle mode, all stations can be set as buffer.
However, only one board can be set per buffer,
and board carriage is performed when the
preceding buffer is set empty. Errors and manual
operations are equal to those for carriage
(automatic mode) in production.
› For PPMC control, an acceleration command cannot
be issued during deceleration.
