Introduction 10
INTRODUCTION
Overview
The ACC-84E Universal Serial Encoder Interface Board can be configured for one of many different
purposes. The most common use provides up to four channels of serial encoders to be read by the
UMAC and Ultralite/MACRO Station controllers, however other purposes include communicating with
galvanometers using protocols such as XY2-100 or maintaining a table of points for use as an expanded
position compare output. The ACC-84E is part of the UMAC or MACRO Pack family of expansion
cards and these accessory cards are designed to plug into an industrial 3U rack system. The information
from these accessories is passed directly to either the UMAC or MACRO Station CPU via the high
speed JEXP expansion bus. ACC-84E supports different protocols depending on the option ordered.
These protocols are programmed into an on-board FPGA upon manufacturing. Multiple common
protocols are supported at the moment and future developments of additional protocols are feasible.
Currently, ACC-84E supports the following encoder protocols:
SSI Synchronous Serial Interface
EnDat 2.2 EnDat 2.2 Interface from HEIDENHAIN
Yaskawa Yaskawa Sigma II/III/V Feedback Support
Tamagawa Tamagawa OAS and SA Absolute Encoders
Panasonic A4 and A5 Encoder Series
Mitutoyo Mitutoyo ENSIS® high-speed serial protocol (AT503/AT503A/ST70X)
BiSS B/C BiSS B/C Unidirectional
Mitsubishi Mitsubishi Serial Encoder Protocol for HG-X Servo Motors
Omron 1S Omron 1S Series Serial Encoders
Alternately, the ACC-84E additionally could be ordered for one of the following alternate uses.
XY2-100 XY2-100 Interface for X and Y Coordinate Communication
TBC Table-Based Position Compare for expanded position compare functionality
Each ACC-84E can only support one of the protocols mentioned above for all four channels. If the
customer has two different protocols in the system, two separate ACC-84E cards should be used.
Since ACC-84E when used to read serial encoders is strictly a feedback input card, if the feedback is
intended to be used as the feedback for closed loop servo control, the servo command should be sent
out to the amplifier using a UMAC axis interface card depending on the signal and control type required
by amplifier. Here is a list of possible axis interface cards available for UMAC systems:
ACC-24E2 Digital amplifier breakout w/ TTL encoder inputs or MLDT
ACC-24E2A Analog amplifier breakout w/ TTL encoder inputs or MLDT
ACC-24E2S Stepper amplifier breakout w/ TTL encoder inputs or MLDT
ACC-24E3 Analog/Digital Output (Power PMAC Compatible Only)
Up to 12 ACC-84E boards can be connected to one UMAC. Because each MACRO Station CPU can
service only eight channels of servo data, only two fully populated ACC-84E boards can be connected
to the MACRO-Station. The ACC-84E board will take the data from a serial encoder and process it as
up to four 24-bit binary parallel words depending on protocol specifications. This data can then

processed in the UMAC or MACRO Station encoder conversion table for position and velocity
feedback. With proper setup, the information can also be used to commutate brushless and AC
induction motors.

Mounting and Installation 15
MOUNTING AND INSTALLATION
To connect a UMAC accessory, simply slide the board into any open slot of the UMAC rack.
Customarily, accessories are installed from left to right as follows:
CPU
Fieldbus
Axes Cards
I/O Cards
Power Supply
10, 15, or 21-slot rack
Prior to installation, make sure that you have set the jumpers and address settings to your desired
requirements. Use the guide tracks that have been installed in the empty slots of your UMAC system
when installing a board.
As you slide the board into the rack, use caution to ensure none of the components on the board make
contact with the front plates of the boards on either side. Getting the front plate flush with the front of
the rack and turning the front screws firmly will ensure a good connection with the backplane.
When removing a board from the system, the user must first pull out any wired connections from the
top, bottom, and front panels then loosen the pem-nuts on the front of the rack. Next, the user can gently
pull the board from the rack and use caution to ensure that none of the components on the board make
contact with the boards on either side.
Caution
This product contains D-SUB style connectors. Do
not overtighten any screws on mating connectors,
and when possible, only tighten by hand.
Overtightening, such as with manual or electric
tools, may lead to the mating nut detaching when
subsequently unscrewed, which may result in
damage to the product, other electronics, and/or
injury.

HARDWARE SETUP
The ACC-84E uses expansion port memory locations defined by the type of PMAC (Power, Turbo, or
MACRO) to which it is directly communicating.
Hardware Dimensions
While the connector locations and board size will be identical across all revisions of the ACC-84E,
jumpers changed in both label and location from revision 102 to 104 and as such are not shown below.
Similarly, the LEDs on the front of the accessory are only present on revision 104 and later.
Dimensions listed 

Diagnostic LEDs
Starting in Rev. 104 and later, there are 4 diagnostic LEDs on the front of the ACC-84E labeled “ENC1”
through “ENC4”. During normal operation, all four LEDs should remain lit. If any are not lit, this
indicates an issue with the +5V signal on the corresponding encoder, such as a short. If the LED remains
unlit without any connector attached, this likely indicates a hardware issue.

Some jumpers before Rev. 104 and all of the jumpers at and after Rev. 104 add 120 Ohm termination
resistors between differential pairs of signals. On early revisions, these were jumpers 10-21, and on
later revisions, they were jumpers 1-3, 11-13, 21-23, and 31-33. While some protocols require these
resistors at all times, in certain cases it may be beneficial to add the jumpers and use them even when
not required, such as when using excessively long cables.

Signal Format
The signal format for the encoder is dependent on the particular protocol, but in all protocols, there is a
“strobe” and/or “clock” output from the controller, and a data channel into the processor from the
encoder. The encoder is queried synchronously with the Power/Turbo PMAC’s phase or servo clock,
and the incoming serial data is latched into a memory-mapped register for the processor to read.

Connections
Encoders are connected to the ACC-84E through four 9-pin D-sub connectors. Two connectors on the
top side of the rack for encoders 1 and 2, and two connectors in the bottom side for encoders 3 and 4.

Encoder Specific Connection Information
Yaskawa Sigma II/III/V Encoders
Yaskawa Sigma II/III/V absolute encoders require a 3.6V battery to maintain the multi-turn data while
the controller is powered down. This battery should be placed outside of the ACC-84E and the Yaskawa
Sigma II/III/V encoder, possibly on the cable. The battery should be installed between orange (+3.6V)
and orange/black wires (GND). Use of ready-made cables by Yaskawa is recommended. (Yaskawa part
number: UWR00650)

The previous diagram shows the pin assignment from mating IEEE 1394 Yaskawa Sigma II connector
to ACC-84E encoder input. The Molex connector required for IEEE 1394 can be acquired as receptacle
kit from Molex, 2.00mm (.079") Pitch Serial I/O Connector, Receptacle Kit, Wire-to-Wire, Molex Part
Number: 0542800609.
Note
Yaskawa Encoder expects a supply voltage of 5V with less than
5% tolerance. Make sure voltage drop is not caused by excessive
wire length.
Note
Encoder wire shield must be connected to chassis ground on both
encoder and connector ends.
Note
Yaskawa Sigma II/III/V require a 120Ω termination resistor
between SDI and SDO twisted pair lines on ACC-84E side.
