Speed
matching operation
Executes the speed matching operation for
-
both wheels of a wide trolley driven by
separate travel motors to ensure smooth
movement.
Decelerates at a point before the target posi-
tion to stop the trolley just in front of the
target position.
Deceleration-start points, stopping posi-
tions, return positions, etc. are determined
by sensor inputs sent from the photo-electric
switch, limit switch, etc.
Fixed volumes liquid-mixing unit
This is a liquid-mixing unit which uses
delivery pumps whose feed rates per rotation
are fixed.
The volumes of liquid fed from each tank are
set by using the digital switch.
Independent 2-axis
plane
control
Moves the table transversely and lon-
gitudinally to permit drilling of a workpiece.
2
drills (small, large) are used, each of which
is selected and controlled by the program-
mable controller.
Up
to
8
axes can be controlled by
1
program-
mable controller, but linear interpolation and
arc interpolation are not supported.
However, interlocked operations can be con-
trolled by using multi-axis synchronizing sig-
nals.
