INTRODUCTION
The PMAC2 PCI (part number 400-603367-10x) is a member of the PMAC family of boards optimized for interface to sinewave or direct-PWM servo drives and to pulse-and-direction stepper drives. Its software is capable of eight axes of control. It can have up to eight channels of on-board axis interface circuitry. It can also support up to eight channels of off-board axis interface circuitry through its expansion port, connected to Acc-24P or Acc-24P2 ISA-format boards. Acc-24 boards in PCI format are not yet available.
The PMAC2 PCI is a full-sized PCI-bus expansion card, with a small piggyback board containing the
CPU board. This piggyback board occupies part of the next slot, but ½-sized boards are permitted in this next slot. While the PMAC2 PCI is capable of PCI bus communications, with or without the optional onboard dual-ported RAM, it does not need to be inserted into a PCI expansion slot. Communications can be done through the standard RS-232/RS-422 serial port. Standalone operation is possible.
Board Configuration

Option 1 provides an additional four channels of on-board axis interface circuitry, identical to the standard first four channels. The key components on the board are the DSPGATE1 IC at U7 and connectors J11 and J12.
Option 2: Dual-Ported RAM
Dual-ported RAM provides a very high-speed communications path for bus communications with the host computer through a bank of shared memory. DPRAM is advised if more than 100 data items per second are to be passed between the controller and the host computer in either direction.
Option 2 provides an 8k x 16 bank of dual-ported RAM. The key component on the board is U28.
Introduction 1
PMAC2 PCI Hardware Reference Manual
Option 5xF: CPU Speed Options
Option 5CF: 80MHz DSP563xxx CPU (160MHz 56002 equivalent)
Option 5EF: 160MHz DSP563xxx CPU (320MHz 56002 equivalent)
Option 5AF: 40MHz DSP563xx CPU (80MHz 56002 equivalent) Default configuration provided automatically if no CPU option ordered.
Option 6: Extended Servo Algorithm
The standard PID servo algorithm with feedforward and notch filter is suitable for most applications.
Systems with difficult dynamics, especially with significant flexibility, may require a more powerful servo algorithm, such as the Extended Servo Algorithm (ESA).
Option 7: Plate Mounting
Option 7 provides a mounting plate connected to the PMAC2 PCI with standoffs. It is used to install the PMAC2 PCI in standalone applications.
Option 8: High-Accuracy Clock Crystal
The PMAC2 PCI has a clock crystal (component Y1) of nominal frequency 19.6608MHz (~20MHz).
The standard crystal’s accuracy specification is +/-100 ppm.
Option 8A provides a nominal 19.6608MHz crystal with a +/-15 ppm accuracy specification.
Option 10: Firmware Version Specification
Normally the Turbo PMAC2 PCI is provided with the newest released firmware version. A label on the
U10 flash memory IC on the CPU board 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 8 or 16 channels of on-board multiplexed analog-to-digital converters. 1 or 2 of these converters are read every phase interrupt. The analog inputs are not optically isolated, and each can have a 0 – 5V input range, or a +/-2.5V input range, individually selectable.
Option 12 provides an 8-channel 12-bit A/D converter. The key components on the board are U28 and connector J1.
Option 12A provides an additional 8-channel 12-bit A/D converter. The key component on the board is U29.
Option 16: Battery-Backed Parameter Memory
The contents of the standard memory are not retained through a power-down or reset unless they have been saved to flash memory first. Option 16 provides supplemental battery-backed RAM for real-time parameter storage that is ideal for holding machine state parameters in case of an unexpected powerdown. The battery is located at component BT1.
Option 16 provides a 16k x 24 bank of battery-backed parameter RAM in components U6, U9, and
U15 on the CPU board.
2 Introduction
PMAC2 PCI Hardware Reference Manual
HARDWARE SETUP
Piggyback CPU Board Jumper Configuration
Watchdog Timer Jumper
Jumper E1 on the Turbo CPU board must be OFF for the watchdog timer to operate. This is an important safety feature, so it is vital that this jumper be OFF in normal operation. E1 should be put ON only to debug problems with the watchdog timer circuit.
Dual-ported RAM Source Jumper
Jumper E2 must connect pins 1 and 2 to access dual-ported RAM from the baseboard. To use Option 2
DPRAM on the baseboard, jumper E2 must be in this setting.
Jumper E2 must connect pins 2 and 3 to access dual-ported RAM through the JEXP expansion port. To use DPRAM on an external accessory board, jumper E2 must be in this setting.
Power-Up State Jumpers
Jumper E4 on the Turbo CPU board must be OFF, jumper E5 must be ON, and jumper E6 must be ON, in order for the CPU to copy the firmware from flash memory into active RAM on power-up/reset. This is necessary for normal operation of the card. (Other settings are for factory use only.)
Firmware Load Jumper
If jumper E7 on the CPU board is ON during power-up/reset, the board comes up in bootstrap mode, which permits the loading of new firmware into the flash-memory IC on the board. When the PMAC
Executive program tries to establish communications with a board in this mode, it will detect automatically that the board is in bootstrap mode and ask what file to download as the new firmware.
Jumper E7 must be OFF during power-up/reset for the board to come up in normal operational mode.
Flash Memory Bank Select Jumpers
The flash-memory IC in location U10 on the Flex CPU board has the capacity for eight separate banks of firmware, only one of which can be used at any given time. The eight combinations of settings for jumpers E10A, E10B, and E10C select which bank of the flash memory is used. In the factory production process, firmware is loaded only into Bank 0, which is selected by having all of these jumpers OFF.
Base Board Jumper Configuration
Servo and Phase Clock Direction Control
Jumper E1 should be off if the board is using its own internally generated phase and servo clock signals.
In this case, these signals are output on spare pins on the J5A RS-422 serial-port connector, where they can be used by other PMAC controllers set up to take external phase and servo clock signals.
Jumper E1 should be on if the board is using externally generated phase and servo clock signals brought in on the J5A RS-422 serial port connector. In this case, another PMAC controller generates the clock signals and output is on its serial port connector. Commonly, serial communications are also shared over a multi-drop RS-422 cable, with software addressing of the cards matching the I0 serial card number for each controller. Alternately, the phase and servo clock signals can come from clock signals involved in the process.
If E1 is on for external phase and clock signals, and these clock signals are not brought in on the serial port connector, the watchdog timer will trip immediately and shut down the board.
Hardware Setup 3
PMAC2 PCI Hardware Reference Manual
In order to change the state of the card between use of internal clock and use of external clock, the card must be re-initialized (either powered up with jumper E3 on, or given the $$$*** command) with jumper E1 in the new state. Before the card is reset again, a SAVE command must be issued to store the new internal settings.
CPU Frequency Control Jumpers
If variable I46 is set to the default value of zero, jumpers E2 and E4 on the base PMAC2 PCI board control the frequency at which the CPU will operate (or attempt to operate). Generally this will be the highest frequency at which the CPU is rated to operate.
If jumpers E2 and E4 are both OFF, the CPU will operate at a 40MHz frequency.
If E2 is ON and E4 is OFF, the CPU will operate at a 60MHz frequency.
If E2 is OFF and E4 is ON, the CPU will operate at an 80MHz frequency.
If I46 is set to a value greater than zero, E2 and E4 are not used. The CPU frequency is set to 10MHz
(I46+1)
Re-Initialization Jumper
If E3 is off during power-up/reset, the controller will load its last saved set-up parameters from flash memory into active memory. This is the setting for normal operation.
If E3 is on during power-up/reset, the controller will load its factory-default set-up parameters from firmware into active memory. Generally, this is done only if communications cannot be established with the card when it comes up in normal operational mode.
Encoder Sample Clock Source Jumpers
Jumpers E13 and E14 control the source of the SCLK encoder-sampling clock for each servo IC. The default setting no jumper installed means that the SCLK signal comes from the servo IC and is output on the JMACH connectors. This setting is suitable for all but a few very special applications.
Serial Port Selection Jumper
Jumpers E17 and E18 control which serial-port connector is used. If E17 and E18 connect their pins 1 and 2, the 10-pin RS-232 port connector J5 is used. If E17 and E18 connect their pins 2 and 3, the 26-pin
RS-422 port connector J5A is used. The RS-422 port must be used if several cards are to be daisychained together on a single multi-drop cable.
Output Disable State Jumpers
Jumpers E111 through E118 control the hardware state of the digital command output signals for each channel when the amplifier enable signal for that channel is in the disable state (false). Jumper E11 n ( n =
1 to 8) controls the output signals for channel n on the board.
If E11 n is off (default), the command output signals for channel n are still active when the amplifier enable signal is in the disable state. The Turbo PMAC software should be commanding a net zero command to be output on these signals and the amplifier enable signal should be used by the amplifier so that no command output will cause action if it is receiving a disable signal. The off setting should be used when DAC output format is selected for the channel.
If E11 n is on, the command output signals for channel n are tri-stated when the amplifier-enable signal is in the disable state. This setting is used only with direct-PWM power-block amplifiers that do not use amplifier enable to gate the PWM signals, and in which the zero-command format of 50% top on-time, and 50% bottom on-time cannot be tolerated in the disable state.

PMAC2 PCI Hardware Reference Manual
Resistor Pack Configuration
Termination Resistors
The PMAC2 PCI provides sockets for termination resistors on differential input pairs coming into the board. As shipped, there are no resistor packs in these sockets. If these signals are brought long distances into the PMAC2 PCI board and ringing at signal transitions is a problem, SIP resistor packs may be mounted in these sockets to reduce or eliminate the ringing.
All termination resistor packs have independent resistors (no common connection) with each resistor using two adjacent pins. The following table shows which packs are used to terminate each input device:

Pull-Up/Pull-Down Resistors
The differential input signal pairs to the PMAC2 PCI have user-configurable pull-up/pull-down resistor networks to permit the acceptance of either single-ended or differential signals in one setting, or the detection of lost differential signals in another setting.
The ‘+’ inputs of each differential pair each have a hard-wired 1 kohm pull-up resistor to +5V. This cannot be changed.
The ‘-’ inputs of each differential pair each have a hard-wired 2.2 kohm resistor to +5V; each has another
2.2 kohm resistor as part of a socketed resistor pack that can be configured as a pull-up resistor to +5V, or a pull-down resistor to GND.
If this socketed resistor is configured as a pull-down resistor (the default configuration), the combination of pull-up and pull-down resistors on this line acts as a voltage divider, holding the line at +2.5V in the absence of an external signal. This configuration is required for single-ended inputs using the ‘+’ lines alone; it is desirable for unconnected inputs to prevent the pick-up of spurious noise. It is permissible for differential line-driver inputs.
If this socketed resistor is configured as a pull-up resistor (by reversing the SIP pack in the socket), the two parallel 2.2 kohm resistors act as a single 1.1 kohm pull-up resistor, holding the line at +5V in the absence of an external signal. This configuration is required if encoder-loss detection is desired; or if complementary open-collector drivers are used. It is permissible for differential line-driver inputs even without encoder loss detection.
If Pin 1 of the resistor pack (marked by a dot on the pack) matches Pin 1 of the socket (marked by a wide white line on the front side of the board and a square solder pin on the back side of the board), then the pack is configured as a bank of pull-down resistors. If the pack is reversed in the socket, it is configured as a bank of pull-up resistors.

Connections
Mounting
The PMAC2 PCI can be mounted in one of two ways: in the PCI bus, or using standoffs.
PCI bus: To mount in the PCI bus, simply insert the P1 card-edge connector into the PCI socket. If there is a standard PC-style housing, a bracket at the end of the PMAC2 PCI board can be used to screw into the housing to hold the board down firmly.
Standoffs: At each of the four corners of the PMAC2 PCI board, there are mounting holes that can be used to mount the board on standoffs.
Power Supply Connection
The standard PMAC2 PCI requires only 5V power: 3A in a 4-channel configuration, 4A in an 8-channel configuration (with Option 1). If the Option 12 A/D converters are installed, a –12V supply is also required. In this case, a +12V supply also can be passed through the card and out to the analog devices feeding the A/D converters.
The power can be provided in several ways:
Bus connector: If the PMAC2 PCI is mounted in an electrically active PCI bus slot, it automatically draws its 5V and +/-12V power from the bus.
Terminal block: The TB1 2/4-point terminal block can be used to bring in 5V power, especially in standalone applications. Point 1 is GND; Point 2 is +5V. Points 3 and 4 are needed only if the
Option-12 A/D converters are ordered.
JMACH connectors: Up to 2A may be brought in through each 100-pin JMACH connector from an
Acc-8 board or its equivalent, provided the cable is 500mm (20 inches) or less in length.
Machine Port Connections
The PMAC2 PCI has a 100-pin high-density header for each pair of servo interface channels. Through this connector pass all of the digital signals to and from the amplifier, encoder, and flags for the two channels. Typically, this header is connected with a matching Delta Tau Acc-8 family 2-channel breakout board or equivalent through a provided 100-pin flat cable.
The machine port connectors are:
J9 (JMACH1)
J10 (JMACH2) Board Channels 3 and 4
J11 (JMACH3) Board Channels 5 and 6 (Option 1 required)
J12 (JMACH4)
Board Channels 1 and 2
Board Channels 7 and 8 (Option 1 required)
Display Port
The J6 (JDISP) display port provides a 14-pin IDC header for connection to the Acc-12 family of displays. Flat cables are provided with each of these displays for direct connection between the display and this port.
6 Hardware Setup
PMAC2 PCI Hardware Reference Manual
Multiplexer Port
The J2 (JTHW) multiplexer port provides eight TTL-compatible 5V CMOS inputs and eight TTLcompatible 5V CMOS outputs on a 26-pin IDC header. These can be used directly as general-purpose digital I/O, or with PMAC2’s special M-variable support (TWB, TWD, TWR, and TWS formats), they can be used to support hundreds, or even thousands of multiplexed I/O points on accessory boards.
Delta Tau provides the following accessory boards that can be connected to the multiplexer port. Each comes with a flat cable for direct connection to the port.
Acc-8D Option 7 Resolver-to-Digital Converter Board
Acc-18 Thumbwheel Board
Acc-34 family of Digital I/O Boards
Acc-35A and B Extender Boards
I/O Port
The J3 (JIO) I/O port provides 32 TTL-compatible 5V CMOS I/O points on a 40-pin IDC header.
Direction is selectable by byte. These are used as general-purpose digital I/O points. Acc-21A provides a convenient connections adapter from this port to OPTO-22 style boards.
Serial Ports
The PMAC2 PCI has two serial-port connectors. Only one of these can be used in an application. J5 is a
10-pin IDC header for RS-232 communications. It can be connected to a standard DB9 RS-232 connector on a host computer or terminal via a flat cable such as the Acc-3L. A commercially available
DB9-to-DB25 adapter can be added to this flat cable if the host computer or terminal has a DB25 serial connector. Jumpers E17 and E18 on the PMAC2 PCI must connect pins 1 and 2 to use this port.
J5A is 26-pin IDC header for RS-422 communications. It can be connected to a standard DB25 RS-422 connector on a host computer or terminal via a flat cable such as the Acc-3D. Jumpers E17 and E18 on the PMAC2 PCI must connect pins 2 and 3 to use this port.
A/D-Converter Port
If the Option 12 A/D converters are ordered, the J1 (JANA) analog-input port is provided on the PMAC2 on a 20-pin IDC header. Option 12 provides eight analog inputs at 0 – 5V, or +/-2.5V levels. Option 12A provides eight additional analog inputs at these levels. The +12V and –12V supplies can either be brought in on this connector, or brought out on it for the external analog circuitry, if they have been brought in through TB1 or P1.
Handwheel Port
The J7 (JHW) handwheel port provides two limited supplemental channels, each with a 2-channel encoder input, and a pulse-and-direction or PWM top-and-bottom pair output. All inputs and outputs are digital 5V differential line-driver pairs.
Hardware Setup 7
PMAC2 PCI Hardware Reference Manual
COMMUNICATIONS SETUP
Delta Tau provides communication tools that take advantage of the PCI bus Plug and Play feature of 32bits Windows ® based computers. Starting with MOTIONEXE.EXE version 10.32.00, which is included in PEWIN32 version 2.32 and newer, a PMAC2 PCI board plugged in a PCI bus slot will be recognized by the operating system when the computer is booted up. The available PCI address, dual-ported RAM address and Interrupt lines are set automatically by the operating system and can be checked (but not modified) in the MOTIONEXE.EXE application.
Open MOTIONEXE and press Setup for the
PCI device desired
The PMAC2 PCI board may have the optional on-board dual-ported RAM circuitry, which is ordered through Option-2. If the dual-ported RAM circuitry is not on-board, manually disable its automatically assigned use through the setup page of MOTIONEXE:
MOTIONEXE version number
Disable Interrupts and Dual-ported
RAM if not used
The MOTIONEXE application will look first for PMAC PCI boards on the PCI bus and will assign device numbers sequentially from Device0 to each PMAC PCI until all the PMAC PCI boards found have a device number assigned. Then, manually add other devices for either ISA bus or Serial port communications.
After each PMAC has a device number assigned to it, communications through the PCI bus are identical to the ISA bus. Any application written for the ISA bus using the Delta Tau provided 32-bits communication libraries provided will not require any further change and the process is transparent.
8 Communications Setup
PMAC2 PCI Hardware Reference Manual
Note:
For example, if a Device0 for serial RS-232 communications was defined before a
PMAC PCI board was installed in the computer, its setup information will be overwritten by the MOTIONEXE application when the PMAC2 PCI board is found. Therefore, it is very important to take note of the all the devices and their parameters defined in MOTIONEXE before installing a new PMAC board in the computer.

The JMACH4 connector provides the interface pins for channels 7 and 8. Usually, it is connected to a breakout board, such as one of the Acc-8x family of boards, or an application-specific interface board.
TB1 (2/4-Pin Terminal Block)
This terminal block can be used to provide the input for the power supply for the circuits on the PMAC2 board when it is not in a bus configuration. When the PMAC2 is in a bus configuration, these supplies come through the bus connector from the bus power supply automatically; in this case, this terminal block should not be used.

Note: The normally closed relay contact is open while PMAC2 is operating properly — it has power and the watchdog timer is not tripped. This contact is closed when the PMAC2 is not operating properly (either the PMAC has lost power or the watchdog timer has tripped). The normally open relay contact is closed while PMAC2 is operating properly, and open when PMAC2 is not operating properly.
