PMAC2A-PC/104
Introduction

Option 6: Extended Firmware Algorithm
Option 6 provides an Extended (Pole-Placement) Servo Algorithm firmware instead of the regular servo
algorithm firmware. This is only required in difficult-to-control systems (resonances, backlash, friction,
disturbances, changing dynamics).
Option 6L: Multi-block lookahead firmware
Option 6L provides a special lookahead firmware for sophisticated acceleration and cornering profiles
execution. With the lookahead firmware PMAC automatically controls the speed along the path (but
without changing the path) to ensure that axis limits are not violated.
Option 10: Firmware Version Specification
Normally the PMAC PCI-Lite is provided with the newest released firmware version. A label on the
memory IC shows the firmware version loaded at the factory. Option 10 provides for a user-specified
firmware version.
Option 12: Analog-to-Digital Converters
Option 12 permits the installation of 2 channels of on-board analog-to-digital converters with ±10V input
range and 12-bits resolution. The key component installed with this option is U20.
ACC-1P: Axis expansion piggyback board
ACC-1P provides 4 additional channels axis interface circuitry
for a total of 8 servo channels, each including:
•
12-bit ±10V analog output
•
Pulse-&-direction digital outputs
•
3-channel differential/single-ended encoder input
•
4 input flags, 2 output flags
•
3 PWM top-and-bottom pairs (unbuffered)
ACC-1P Option 1: I/O ports
Option 1 provides the following ports on the ACC-1P axes expansion board for digital I/O connections.
•
Multiplexer Port: this connector provides eight input lines and eight output lines at TTL levels.
When using the PMAC ACC-34x type boards these lines allow multiplexing large numbers of
inputs and outputs on the port. Up to 32 of the multiplexed I/O boards may be daisy-chained on
the port, in any combination.
•
I/O Port: this port provides eight general-purpose digital inputs and eight general-purpose digital
outputs at 5 to 24 VDC levels. This 34-pin connector was designed for easy interface to OPTO-
22 or equivalent optically isolated I/O modules when different voltage levels or opto-isolation to
the PMAC2A-PC/104 is necessary.
•
Handwheel port: this port provides 2 extra channels, each jumper selectable between encoder
input or pulse output.
ACC-1P Option 2: Analog-to-Digital Converters
Option 2 permits the installation on the ACC-1P of 2 channels of analog-to-digital converters with ±10V
input range and 12-bits resolution. The key component installed with this option is U20.
