Turbo PMAC Configurations
Turbo PMAC controllers can come in a variety of different physical configurations. Fundamentally, these
break into three different types: board-level, rack-mounted, and boxed. Each of these types is described
below.
Board-Level Designs
There are multiple board-level implementations of the Turbo PMAC. These designs can be used as
expansion cards in a backplane bus, but they do not have to be installed in the bus, either for initial setup,
or in the actual application. All have serial communications links as well.
Presently, there are Turbo PMAC designs for the ISA, VME and PCI buses. These come with PMAC-
style or PMAC2-style interfaces. Lite versions of the Turbo PMAC have only one on-board Servo IC,
providing four channels of servo interface circuitry. Ultralite versions of the Turbo PMAC2 replace on-
board servo interface circuitry with MACRO-ring interfaces; the actual servo interface circuitry is located
in a remote MACRO Station or embedded in a MACRO drive.
The following table summarizes the board-level Turbo PMAC implementations available as of this
writing (mid-2003):

UMAC Rack-Mounted Designs
Rack-mounted implementations of the Turbo PMAC are called UMAC (Universal Motion and
Automation Control). These implementations consist of a modular set of 3U-format (100mm x 160mm)
Euro-cards installed in a common backplane and mounted in a Euro-rack. The modular style permits the
easy customization of the controller to the User precise needs. The rack mounting provides easy
installation and connection in industrial machines, without the difficulties of wiring into computer-
mounted controllers. High-speed wire communications links such as USB and Ethernet provide
communications speeds close to those of backplane buses.
UMAC Turbo
The UMAC Turbo is a rack-mounted Turbo PMAC system in which the 3U-format boards are connected
across a backplane board that has the physical format of a VME bus (96-pin DIN connectors), but is not
electrically or software compatible with the VME bus. The field wiring comes out of the top, bottom, and
(sometimes) front sides of the cards.
There are a wide variety of UMAC boards. This includes:
Turbo CPU board with PC/104 interface
Axis boards: PWM, analog, stepper/encoder
Sensor boards: Sinusoidal Encoder, SSI, Absolute Encoder, resolver
Digital I/O boards: TTL and Isolated 24V, sinking and sourcing
A/D converter boards: 12-bit and 16-bit
High-speed communications board: USB or Ethernet
