Introduction 1
INTRODUCTION
Overview
The Accessory 8F digital interface board (ACC-8F) for the PMAC2 family of controllers
provides pinouts for 2 channels with digital-input amplifiers. The amplifier inputs are direct
PWM commands.
The ACC-8F board has one flat-cable connection to the PMAC2. The connection to each digital
amplifier is through a separate Mini-D connector. Encoder inputs can be brought in either
through DB15 connectors, IDC Headers, or removable modular terminal blocks. Main flag
inputs are brought in through DB9 connectors or removable modular terminal blocks.
Supplementary flag inputs can be interfaced via either the DB15 connectors, removable modular
terminal blocks, or an IDC header.
Note:
Early prototype ACC-8F boards (Part # 602481-100) were 4-channel boards.
The pinouts on some connectors were different. Pilot-run ACC-8F boards (Part
# 602481-101) had DB-37 amplifier connectors instead of Mini-D 36-pin
amplifier connectors.
Features
Detects a loss of any encoder quadrature signal (A+, A-, B+, B-) or if the encoder is not
connected. It will bring AFLT1+ and AFLT2+ lines (JMAC1 pins 19 and 69) low in either case.
Supports Hall-effect signals for power-on phase information through its supplemental U, V, W
and T inputs.
Decodes U, V, W, T and Index signals (Option 6) if they are encoded on the C+/C- channels (i.e.
Yaskawa multiplexed encoders). Jumper selectable.
Accepts regular quadrature encoder feedback (A, B,C/Z) either single ended or differential.
(Default).
Has built-in power delay circuit (Option 6) which will supply a power to an encoder only after a
PMAC2’s hardware and software circuits were determined to function properly. If this feature is
selected by jumping pins 2 and 3 of E24, it is assured that a motor power-on information is read
correctly by PMAC2. Delta Tau recommends to use this feature when working with encoders
that send power-on information right after the encoder power is applied.(i.e. Yaskawa
multiplexed encoders )
The main input flags (HOME, PLIM, MLIM and USER) are optically isolated with sinking or
sourcing capability to 24 V. AC opto modules are used.
Amplifier Fault Detection. If the amplifier fault condition causes low on FLTx+ or FLTx- (P5,
P6), ACC 8F passes amplifier FCx-A, FCx-B, FCx-C and FCx-D fault code bits to PMAC2 via
CHUx+, CHVx+, CHWx+ and CHTx+ lines. If this function is not required, remove E21 and
E23 jumpers.

Introduction
2
The ACC-8F has a 6-point terminal block (TB3) that permits a +5V supply to be brought in
externally for encoders and the like. Alternatively, the +5V supply can come from the PMAC2
through the ACC-8F if the jumper E1 on ACC-8F is ON. If more than about 250 mA will be
used through the ACC-8F, the +5V power should be brought in through this terminal block, and
the E1 jumper should be OFF to keep this supply from fighting the +5V supply on PMAC2.
Options
Option 1: Encoder, Supplemental flags and Main flags use terminals (TB1, TB2, TB4, TB5)
Option 2: Encoder, Supplemental flags and Main flags use DB connectors (P1, P2, P3, P4)
Option 4: Rail mount
Option 6: Mulitplexed encoder and power-on read option
ACC-8F Limit and Flag Wiring
The ACC-8F allows the user to use sinking or sourcing position limits and flags to the PMAC2.
The optoisolator IC used is a PS2705-4NEC-ND quad photo-transistor output type. This IC
allows the current to flow from return to flag (sinking) or from flag to return (sourcing).
ACC-8F Circuit
A sample of the positive limit circuit is shown below. The 4.7K resistor pack used will allow
12-24V flag inputs. If lower voltages are needed, then a lower value resistor could be used in its
place (470Ωfor 5V). Please call the factory if this is the case for your application.
Connecting to the ACC-8F
The following diagrams illustrate the sinking and sourcing connections to an ACC-8F.

Introduction 3
The actual connection to the ACC-8F can be accomplished several ways. The connection shown
in below is a photo-transistor device which is open collector or sinking. This device will have
0V output when not activated and 12-24V output when activated.
Depending on the output of the flag, the return line (RETn) to the ACC-8F could be wired to the
flag power or ground.
