3.1.2 Stand Alone System Block Diagram Description
{ Spindles can be combined in a multiple spindle configuration controlled by one main con-
troller (Multi Unit) using one set of I/O to control the group of spindles. When communica-
tions requirements, spindle sequencing requirements or spindle quantities are limited, a simp-
ler configuration without a Multi Unit can be set up. This configuration is referred to as a
“Stand Alone” system.
{ In a Stand Alone System, simultaneous communication for up to 31 SAN Units (Spindle
Controllers) can only be accomplished via an RS485 Daisy chain connection on the front of
each Axis unit. The AFC User Console software must be used in conjunction with a PC to
collect and manipulate data from multiple spindles.
{ Additionally, a “Hot -Swap” detachable Keypad/Display can be used on each SAN Unit to
program and monitor the individual spindles.
{ Discrete 24 VDC (Sinking) I/O on the SAN unit provides direct connection with the PLC for
complete individual spindle control when the system is configured as a Stand Alone System.
The spindle I/O for each SAN unit must be individually controlled and monitored
{ Dedicated serial communications with each SAN unit can be provided via an individual
communications port available directly on the optional Keypad/Display Unit (DP2, DP4) that
can be connected to a single SAN unit. Once configured, the system is not dependent on a
PC or software package to transmit data to an external device.
{ A detachable or dedicated PC running the AFC User Console software can be connected
to the multiple spindles in a Stand Alone system for increased data communications or mani-
pulation capabilities.
