2.3 FUNCTIONS
AND OPERATION
OF MODULES
."
The operation
of the component
modules
of Motionpack-l_0
are as follows:
2.3.1 OPERATION
OF MOTION MODULES
The motion modules serve as the key to the control of the Motionpack-110
systems,
and
incorporate
an 8-bit microcomputer.
They read the parameters
and programs
when they are
input from the CRT control
station
or from a personal
computer.
When a start signal
is
received,
they analyze
the program,
generate
position
data,
and control
up to 3 axis and a
spindle modules viaan FA bus.
They also receive position
data,
alarm,
and status
signals
from the axis modules
via
the FA bus, analyze
them,
and transmit
them to the CRT control
station
and personal
computer
for display.
They also process input/output
signals.
The motion module is
communicated
with a micro
PC module
via the FA bus, as well.
The control
block diagram
of motion
modules
is given in Fig. 2.2. Expansion
memories
and interpolation
units
are optionally
available.
