The
TSX CCY 1128
module performs the “electronic cam” function for a rotary axis
rotating in a single, alternating or cyclical direction (with periodic arrival of parts to be
processed) or endlessly (with random arrival of parts to be processed). The axis is
managed by an incremental or absolute encoder.
The
TSX CCY 1128
electronic cam module independently manages up to 128 cams
which can be spread over a maximum of 32 tracks to which 24 discrete physical
outputs and 8 logic outputs can be assigned.
Processing is organized into 4 groups of 8 tracks, with groups 0 and 1 associated
with connector 0 on the module and groups 2 and 3 with connector 1.
The
TSX CCY 1128
module can be used for the following functions: elimination of
axis backlash, position recalibration, capturing measurements (part length, number
of points per revolution, angle of arrival of parts, slip, etc.), anticipation of switching,
parts counter, event generation.
Like all application-specific modules, the
TSX CCY 1128
module can be installed in
any slot of a Premium PLC, except for those specifically for the power supply and the
processor.
Description
The front panel of the
TSX CCY 1128
electronic cam module comprises:
1
A 15-way SUB-D connector for connecting the incremental or absolute encoder
2
A 20-way HE 10 connector for connecting the track outputs of groups 0 and 1
(
connector 0)
3
A 20-way HE 10 connector
for connecting the track outputs of groups 2 and 3
(
connector 1)
4
A 20-way HE connector for connecting the auxiliary inputs and the encoder power
supply
5
Rigid casing, which:
v
Holds the electronic cards
v
Locates and locks the module in its slot
