Select one of the following options to designate the rate of the nozzle
descending speed reduction for pick-up.

(a) The descending motion starts from the pass line (lower or upper pass
line).
When a parameter is set in the "Dclr 2 Stroke" data box, the X/Y
beam descends to the bottom position of the stroke.
(b) The lower pass line is the lowest level of the X/Y beam movement
when the thickness of a previously-placed component (already-placed
component) is 6.5 mm or less.
The upper pass line is the lowest level of the X/Y beam movement
when the thickness of a previously-placed component is more than
6.5 mm. (Only in the placement PCB area)
(5) Pu Descent Dclr 2 [%]
Set a parameter to designate the rate of the speed reduction while the
X/Y beam is descending to the bottom of the stroke remaining.
Unit: %
Data Input Range: 0 to 99
(a) By making the X/Y beam descend at a very low speed for the remain-
der of the stroke (down to the pick-up lower limit), delicate compo-
nents pick-ups can be made in stable conditions.
The set parameter becomes valid only when it is larger than the rate
set in the "Dclr 1" data box.
(b) In the following case, the X/Y beam only descends according to the
parameter in the "Pu descent dclr 1" without making the two-step
speed reduction.

(6) Pu Descent Dclr 2 Stroke [mm]
Set the stroke in the data box, so that the X/Y beam descends at a
very slow speed for the duration of the stroke (speed reduction speci-
fied in the "Pu descent dclr 2").

(a) In the normal case the descending motion starts from the pass line
(lower or upper pass line).
When a parameter is set in the "Dclr 2 Stroke" data box, the X/Y
beam descends to the position of the stroke.
(b) The lower pass line is the lowest level for the X/Y beam movement
when the thickness of a previously-placed component (already-placed
component) is 6.5 mm or less.
The upper pass line is the lowest level of the X/Y beam movement
when the thickness of a previously-placed component is more than
6.5 mm. (Only in the placement PCB area)

(9) Pl Descent Dclr 2 [%]
Set a parameter to designate the rate of the speed reduction when
the X/Y beam descends to the bottom of the remaining stroke (down
to the placement lower limit specified in the "Dclr 2 Stroke" data box).
Unit: %
Data Input Range: 0 to 99
(a) By making the X/Y beam descend at a very low speed, to the bottom
of the remaining stroke (down to the placement lower limit), a deli-
cate component placement can be made in stable conditions. The
set parameter becomes valid only when it is larger than the rate set in
the "Dclr 1" data box.
(b) When press-fit or insertion components must be placed, it is neces-
sary to reduce the descending speed so that while such components
are being placed there will be no strong impulse to the PCBs. How-
ever, if the speed is reduced from the start of the descending motion
up to the component placement, then the duration of the placement
motion will be prolonged. In this case, the time can be shortened by
using only "Dclr 2", with the parameter in the "Dclr 1" data box set to
"Full Speed".

(c) In the following case the X/Y beam descends in accordance with the
parameter in the "Pl descent dclr 1" and without making a two-step
speed reduction.
