9/440HR CNC/Drive System
5B-2
System Module -- This is the largest module in the 9/440HR CNC/Drive
system (left most module). It contains the following circuit boards:
9/440HR CNC Assembly Section
- Processor Board -- This board provides the CNC logic as well as
connections to the 9/Series fiber optic I/O ring, serial ports A and B,
E-Stop connection, and video connection.
- Feedback Board -- Each 1326AB motor’s high--resolution feedback
device (up to 4 available) is wired to this board, which also provides
encoder power. Additional encoder feedback ports are available for
spindle feedback, optional feedback, or analog axis feedback.
Power Assembly
- Power Supply -- This supplies power to the system module as well as
the axis modules. Attach incoming AC three-phase power and 24 V
logic power to this supply.
Interconnecting Power and 9/440HR CNC Assembly Section
- Wiring Board -- spindle outputs, touch probe connections, and the
RIO connection are located on this board, which also interfaces the
9/440HR CNC assembly with the power portion of the 9/440.
The number and type of available feedback ports supported on your
9/440HR system are defined by options installed at the factory. Some
ports may not be enabled. To determine what ports are operational on your
system, refer to the system configuration label located on the outer left side
of your system module. The following table shows catalog numbers and
the feedback ports enabled by them.
