PMAC-PCI Hardware Reference

INTRODUCTION

The PMAC PCI is a member of the PMAC family of boards optimized for interface to traditional servo drives with single analog inputs representing velocity or torque commands. Its software is capable of 8 axes of control. It can have up either eight or four channels of on-board axis interface circuitry.

The PMAC PCI is a full-sized PCI-bus expansion card, with a small piggyback board containing the CPU board. While the PMAC PCI is capable of PCI bus communications, with or without the optional dualported RAM, it does not need to be inserted into an PCI expansion slot. Communications can be done through an RS-232 or RS-422 serial port; standalone operation is possible.

Board Configuration

Base Version

The base version of the PMAC PCI provides a 1-1/2-slot board with:

• 40 MHz DSP56002 CPU

• 128k x 24 0-wait-state flash-backed SRAM

• 512k x 8 flash memory for firmware and user backup

• 2k x 8 EEPROM memory for setup variable backup

• Latest released firmware version

• RS-422 serial interface, PCI (PC) bus interface

• Four channels axis interface circuitry, each including:

• 16-bit +/-10V analog output

• 3-channel differential/single-ended encoder input

• Four input flags, two output flags

• Interface to external 16-bit serial ADC

• Display, control panel, muxed I/O, direct I/O interface ports

• Buffered expansion port

• Clock crystal with +/-100 ppm accuracy

• PID/notch/feedforward servo algorithms

• 1-year warranty from date of shipment

• One manuals CD per set of 1 to 4 PMACs in shipment

(Cables, mounting plates, mating connectors not included)

Option 1: Additional Four Channels Axis Interface Circuitry

• Option 1 provides an additional four channels of on-board axis interface circuitry, identical to the

standard first four channels.

Option 2: Dual-Ported RAM

Dual-ported RAM provides a 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 on-board.

• Option A provides a 20-cm (8") 50-pin 3-connector cable. This cable is necessary when using the

Option 2 board combined with any of the Acc-14D, 24P, 29P, or 36P boards.

Option 2B: High-Speed USB Communications Interface

Option-2B provides the high-speed USB communications interface, which is a faster method of communication than the standard RS-232 communications port.

Introduction 1

PMAC-PCI Hardware Reference

Option 5x: CPU Type

The base PMAC version without options has a 20 MHz CPU with flash memory RAM.

• Option 5A: 40 MHz CPU, zero-wait RAM, flash backup, no battery, (~100% speed increase)

• Option 5B: 60 MHz CPU, zero-wait RAM, flash backup, no battery, (~200% speed increase)

• Option 5C: 80 MHz CPU, zero-wait RAM, flash backup, no battery, (~375% speed increase)

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). This option requires a one-time purchase of the Acc-25 program, which is necessary for tuning the Option-6 firmware.

Option 7: Plate Mounting

• Option 7 provides a mounting plate connected to the PMAC with standoffs. It is used to install the

PMAC in standalone applications.

Option 8A: High-Accuracy Clock Crystal

The PMAC PCI has a clock crystal of nominal frequency 19.6608 MHz (~20 MHz). The standard crystal’s accuracy specification is +/-100 ppm.

• Option 8A provides a nominal 19.6608 MHz crystal with a +/-15 ppm accuracy specification.

Option 10: Firmware Version Specification

Normally the PMAC PCI 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 8 or 16 channels of on-board multiplexed analog-to-digital converters. One or two 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 U20

and connector J30.

• Option 12A provides an additional 8-channel 12-bit A/D converter. The key component on the board

is U22.

Option 15: V-to-F Converter for Analog Input

The JPAN control panel port on the PMAC PCI has an optional analog input called WIPER (because it is often tied to a potentiometer’s wiper pin). PMAC PCI can digitize this signal by passing it through an optional voltage-to-frequency converter, using E-point jumpers to feed this into the Encoder 4 circuitry (no other use is then permitted), and executing frequency calculations using the “time base” feature of the encoder conversion table.

• Option 15 provides a voltage-to-frequency converter that permits the use of the Wiper input on the

control panel port.

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.

Option 16A provides a 16k x 24 bank of battery-backed parameter RAM. This Option requires Option 4A, Option 5A, Option 5B or Option 5C.

2 Introduction

PMAC-PCI Hardware Reference

PMAC Connectors and Indicators

J1 - Display Port (JDISP Port)

The JDISP connector allows connection of the Acc-12 or Acc-12A liquid crystal displays, or of the Acc12C vacuum fluorescent display. Both text and variable values may be shown on these displays using the DISPLAY command, executing in either motion or PLC programs.

J2 - Control-Panel Port (JPAN Port)

The JPAN connector is a 26-pin connector with dedicated control inputs, dedicated indicator outputs, a quadrature encoder input, and an analog input (requires PMAC Option 15). The control inputs are low true with internal pull-up resistors. They have predefined functions unless the control-panel-disable Ivariable (I2) has been set to 1. If this is the case, they may be used as general-purpose inputs by assigning M-variable to their corresponding memory-map locations (bits of Y address $FFC0).

J3 - Thumbwheel Multiplexer Port (JTHW Port)

The Thumbwheel Multiplexer Port, or Multiplexer Port, on the JTHW connector has eight input lines and eight output lines. The output lines can be used to multiplex large numbers of inputs and outputs on the port, and Delta Tau provides accessory boards and software structures (special M-variable definitions) to capitalize on this feature. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in any combination.

J4 - Serial Port (JRS422 Port)

For serial communications, use a serial cable to connect your PC’s COM port to the PMAC’s serial port connector. Delta Tau provides the Acc-3D cable for this purpose, which connects PMAC to a DB-25 connector. Standard DB-9-to-DB-25 or DB-25-to-DB-9 adapters may be needed for a particular setup.

J5 - General-Purpose Digital Inputs and Outputs (JOPTO Port)

PMAC’s JOPTO connector provides eight general-purpose digital inputs and eight general-purpose digital outputs. Each input and each output has its own corresponding ground pin in the opposite row. The 34-pin connector was designed for easy interface to OPTO-22 or equivalent optically isolated I/O modules. Delta Tau’s Acc-21F is a six-foot cable for this purpose.

J6 – Expansion Port (JXIO Port)

This port is only used when connecting to optional PMAC accessory boards.

J7 / J8 - Machine Connectors (JMACH2 / JMACH1 Ports)

The primary machine interface connector is JMACH1, labeled J8 on the PMAC PCI. It contains the pins for four channels of machine I/O: analog outputs, incremental encoder inputs, and associated input and output flags, plus power-supply connections. The next machine interface connector is JMACH2, labeled J7 on the PMAC PCI. Essentially, it is identical to the JMACH1 connector for one to four more axes. It is present only if the PMAC card has been fully populated to handle eight axes (Option 1), because it interfaces the optional extra components.

J9 – Compare Equal Outputs Port (JEQU Port)

The compare-equals (EQU) outputs have a dedicated use of providing a signal edge when an encoder position reaches a pre-loaded value. This is useful for scanning and measurement applications. Instructions for use of these outputs are covered in detail in the PMAC’s User Manual.

J30 – Optional Analog to Digital Inputs (JANA Port)

This optional port is used to bring in the analog signals for the optional analog to digital inputs set. This feature provides up to 16 analog inputs in the range of 0 to 5V unipolar or ±2.5V bipolar.

J31 – Optional Universal Serial Bus Port (JUSB Port)

This optional port allows communicating with PMAC through a standard USB connection.

Introduction 3

PMAC-PCI Hardware Reference

JS1/JS2 – Expansion Ports (JS1/JS2 Ports)

These ports are used only when connecting to optional PMAC accessory boards.

TB1 – Power Supply Terminal Block (JPWR Connector)

This terminal block may be used as an alternative power supply connector if PMAC PCI is not installed in a PCI-bus.

LED Indicators

PMACs with the Option CPU have three LED indicators: red, yellow, and green. The red and green LEDs have the same meaning as with the standard CPU: when the green LED is lit, this indicates that power is applied to the +5V input; when the red LED is lit, this indicates that the watchdog timer has tripped and shut down the PMAC.

The yellow LED located beside the red and green LEDs, when lit, indicates that the phase-locked loop that multiplies the CPU clock frequency from the crystal frequency on the Option CPU is operational and stable. This indicator is for diagnostic purposes only; it may not be present on your board.

The PMAC PCI has an interlock circuit that drops out the ±15V supplies to the analog outputs through a fail-safe relay if any supply on PMAC is lost. In this case, the green LED D15 will be off. The D19 LED will be lit when 5V is applied to PMAC.

JUMPER SUMMARY

On the PMAC, you will see many jumpers (pairs of metal prongs), called E-points. Some have been shorted together; others have been left open. These jumpers customize the hardware features of the board for a given application and must be setup appropriately. The following is an overview of the several PMAC jumpers grouped in appropriate categories. For a complete description of the jumper setup configuration, refer to the PMAC PCI CPU Board E-Point Descriptions section in this manual.

Power-Supply Configuration Jumpers

E85, E87, E88: Analog Circuit Isolation Control – These jumpers control whether the analog circuitry on the PMAC PCI is isolated from the digital circuitry, or electrically tied to it. In the default configuration, these jumpers are off, keeping the circuits isolated from each other (provided separate isolated supplies are used).

E89-E90: Input Flag Supply Control – If E90 connects pins 1 and 2 and E89 is ON, the input flags (+LIMn, -LIMn, and HMFLn) are supplied from the analog A+15V supply, which can be isolated from the digital circuitry. If E90 connects pins 1 and 2 and E89 is OFF, the input flags are supplied from a separate A+V supply brought in on pin 59 of the J7 JMACH2 connector. This supply can be in the +12V to +24V range, and can be kept isolated from the digital circuitry. If E90 connects pins 2 and 3, the input flags are supplied from the digital +12V supply, and isolation from the digital circuitry is defeated.

E100: AENA/EQU Supply Control – If E100 connects pins 1 and 2, the circuits related to the AENAn, EQUn and FAULTn signals will be supplied from the analog A+15V supply, which can be isolated from the digital circuitry. If E100 connects pins 2 and 3, the circuits will be supplied from a separate A+V supply brought in on pin 9 of the J9 JEQU connector. This supply can be in the +12V to +24V range, and can be kept isolated from the digital circuitry.

8 Jumper Summary

PMAC-PCI Hardware Reference

Clock Configuration Jumpers

E3-E6: Servo Clock Frequency Control – The jumpers E3 – E6 determine the servo-clock frequency by controlling how many times it is divided down from the phase-frequency. The default setting of E3 and E4 OFF, E5 and E6 ON divides the phase-clock frequency by 4, creating a 2.25 kHz servo-clock frequency. This setting is seldom changed.

E29-E33: Phase Clock Frequency Control – Only one of the jumpers E29 – E33, which select the phase-clock frequency, may be on in any configuration. The default setting of E31 ON, which selects a 9 kHz phase-clock frequency, is seldom changed.

E34-E38: Encoder Sample Clock – Only one of the jumpers E34 – E38, which select the encoder sample clock frequency, may be on in any configuration. The frequency must be high enough to accept the maximum true count rate (no more than one count in any clock period), but a lower frequency can filter out longer noise spikes. The anti-noise digital delay filter can eliminate noise spikes up to one sample-clock cycle wide.

E40-43: Servo and Phase Clock Direction Control – Jumpers E40-E43 control the software address of the card, for serial addressing and for sharing the servo and phase clock over the serial connector. Card @0 sends the clocks and cards @1-@F receive the clocks. If any of these jumpers is removed, PMAC PCI will expect to receive external servo and phase clock signals on the J4 serial port – if these signals are not provide in this configuration, the watchdog timer will immediately trip.

E48: Option CPU Clock Frequency Control – When PMAC is ordered with Option 5B, E48 setup the CPU clock frequency to either 40 MHz or 60 MHz. If PMAC is ordered with Option 5C additional software, setup is necessary for 80 MHz CPU clock frequency operation.

E98: DAC/ADC Clock Frequency Control – Leave E98 in its default setting of 1-2, which creates a

2.45 MHz DCLK signal, unless you are connecting an Acc-28 A/D-converter board. In this case, move the jumper to connect pins 2 and 3, which creates a 1.22 MHz DCLK signal.

Encoder Configuration Jumpers

Encoder Complementary Line Control – The selection of the type of encoder used, either single ended or differential is made through the resistor packs configuration and not through a jumper configuration.

E22-E23: Control-Panel Handwheel Enable – Putting these jumpers ON ties the handwheel-encoder inputs on the JPAN control-panel port to the Channel 2 encoder circuitry. If the handwheel inputs are connected to Channel 2, no encoder should be connected to Channel 2 through the JMACH1 connector.

E72-E73: Control Panel Analog Input Enable – Putting these jumpers ON ties the output of the Option 10 voltage-to-frequency converter that can process the “WIPER” analog input on the JPAN control panel port to the Channel 4 encoder circuitry. If the frequency signal is connected to Channel 4, no encoder should be connected to Channel 4 through the JMACH1 connector.

E74-E75: Encoder Sample Clock Output – Putting these jumpers ON ties the encoder sample-clock signal to the CHC4 and CHC4/ lines on the JMACH1 port. This permits the clock signal to be used to synchronize external encoder-processing devices like the Acc-8D Option 8 interpolator board. With these jumpers ON, no encoder input signal should be connected to these pins.

Board Reset/Save Jumpers

E50: Flash-Save Enable/Disable Control – If E50 is ON (default), the active software configuration of the PMAC can be stored to non-volatile flash memory with the SAVE command. If the jumper on E50 is removed, this SAVE function is disabled, and the contents of the flash memory cannot be changed.

E51: Re-Initialization on Reset Control – If E51 is OFF (default), PMAC executes a normal reset, loading active memory from the last saved configuration in non-volatile flash memory. If E51 is ON, PMAC re-initializes on reset, loading active memory with the factory default values.

Communication Jumpers

PCI Bus Base Address Control – The selection of the base address of the card in the I/O space of the host PC’s expansion bus is assigned automatically by the operating system and it is not selected through a jumper configuration.

E44-E47: Serial Baud Rate Selection –The configuration of these jumpers and the particular CPU Option ordered will determine the baud rate at which PMAC will communicate through its J4 serial port. For example, when PMAC is ordered with no CPU Options and only the jumpers E45 and E46 are installed, the baud rate will be set at 9600 baud.

E49: Serial Communications Parity Control – Jump pin 1 to 2 for NO serial parity; remove jumper for ODD serial parity.

E54-E65: Interrupt Source Control – These jumpers control which signals are tied to interrupt lines IR5, IR6 and IR7 on PMAC’s programmable interrupt controller (PIC), as shown in the interrupt diagram. Only one signal may be tied into each of these lines.

E110: Serial Port Configure – Jump pin 1 to 2 for use of the J4 connector as RS-232. Jump pin 2 to 3 for use of the J4 connector as RS-422.

E111: Clock Lines Output Enable – Jump pin 1 to 2 to enable the Phase, Servo and INIT lines on the J4 connector. Jump pin 2 to 3 to disable the Phase, Servo and INIT lines on the J4 connector. E111 on positions 1 to 2 is necessary for daisy-chained PMACs sharing the clock lines for synchronization.

I/O Configuration Jumpers

WARNING:

A wrong setting of these jumpers will damage the associated output IC.

E1-E2: Machine Output Supply Configure – With the default sinking output driver IC (ULN2803A or

equivalent) in U13 for the J5 JOPTO port outputs, these jumpers must connect pins 1 and 2 to supply the IC correctly. If this IC is replaced with a sourcing output driver IC (UDN2981A or equivalent), these jumpers must be changed to connect pins 2 and 3 to supply the new IC correctly.

E7: Machine Input Source/Sink Control – With this jumper connecting pins 1 and 2 (default) the machine input lines on the J5 JOPTO port are pulled up to +5V or the externally provided supply voltage for the port. This configuration is suitable for sinking drivers. If the jumper is changes to connect pins 2 and 3, these lines are pulled down to GND – this configuration is suitable for sourcing drivers.

E17A - E17D: Motors 1-4 Amplifier-Enable Polarity Control – Jumpers E17A through E17D control the polarity of the amplifier enable signal for the corresponding motor 1 to 4. When the jumper is ON (default), the amplifier-enable line for the corresponding motor is low true so the enable state is lowvoltage output and sinking current, and the disable state is not conducting current. With the default ULN2803A sinking driver used by the PMAC PCI on U37, this is the fail-safe option, allowing the circuit to fail in the disable state. With this jumper OFF, the amplifier-enable line is high true so the enable state is not conducting current, and the disable state is low-voltage output and sinking current. This setting is not generally recommended.

E17E - E17H: Motors 5-8 Amplifier-Enable Polarity Control – Jumpers E17A through E17D control the polarity of the amplifier enable signal for the corresponding motor 5 to 8. When the jumper is ON (default), the amplifier-enable line for the corresponding motor is low true so the enable state is lowvoltage output and sinking current, and the disable state is not conducting current. With the default ULN2803A sinking driver used by the PMAC PCI on U53, this is the fail-safe option, allowing the circuit to fail in the disable state. With this jumper OFF, the amplifier-enable line is high true so the enable state is not conducting current, and the disable state is low-voltage output and sinking current. Generally, this setting is not recommended.

E28: Following-Error/Watchdog-Timer Signal Control – With this jumper connecting pins 2 and 3 (default), the FEFCO/ output on pin 57 of the J8 JMACH1 servo connector outputs the watchdog timer signal. With this jumper connecting pins 1 and 2, this pin outputs the warning following error status line for the selected coordinate system.

WARNING:

A wrong setting of these jumpers will damage the associated output IC.

E101-E102: Motors 1-4 AENA/EQU voltage configure – The U37 driver IC controls the AENA and

EQU signals of motors 1-4. With the default sinking output driver IC (ULN2803A or equivalent) in U37, these jumpers must connect pins 1 and 2 to supply the IC correctly. If this IC is replaced with a sourcing output driver IC (UDN2981A or equivalent), these jumpers must be changed to connect pins 2 and 3 to supply the new IC correctly.

WARNING:

A wrong setting of these jumpers will damage the associated output IC.

E114-E115: Motors 5-8 AENA/EQU voltage configure – The U53 driver IC controls the AENA and

EQU signals of motors 5-8. With the default sinking output driver IC (ULN2803A or equivalent) in U53, these jumpers must connect pins 1 and 2 to supply the IC correctly. If this IC is replaced with a sourcing output driver IC (UDN2981A or equivalent), these jumpers must be changed to connect pins 2 and 3 to supply the new IC correctly.

E121: XIN6 Motor Selection – Jump 1-2 to bring the QuadLoss signal for Encoder 6 into register XIN6 at Y:$E801 bit 6. Jump 2-3 to bring the QuadLoss signal for Encoder 7 into register XIN6 at Y:$E801 bit

Piggyback CPU (FLEX) Board Jumper Configuration

Watchdog Timer Jumper

Jumper E1 on the Non-Turbo CPU board must be OFF for the watchdog timer to operate. This is a very important safety feature, so it is vital that this jumper be OFF in normal operation. E1 should only be put ON 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 (non-Turbo addresses $Dxxx, Turbo addresses $06xxxx) from the base board. If it is desired to use the Option 2 DPRAM on the base board, jumper E2 must be in this setting. All Delta Tau base boards except the PMAC(1)-PC board have the option for installing DPRAM on the base board.

Jumper E2 must connect pins 2 and 3 to access dual-ported RAM (non-Turbo addresses $Dxxx, Turbo addresses $06xxxx) through the JEXP expansion port. If it is desired to use DPRAM on an external accessory board, jumper E2 must be in this setting. The PMAC(1)-PC base board (part # 602191-10x) does not have the option for installing on-board DPRAM; it requires the external Option 2 DPRAM board (part #602240-10x) for this functionality. Use of this DPRAM board, interfacing through the JEXP port, requires E2 to connect pins 2 and 3.

Jumper Summary 11

PMAC-PCI Hardware Reference

Power-Up State Jumpers

Jumper E4 on the Non-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 automatically detect that the board is in bootstrap mode and ask you what file you want 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.

Installation

The Flex CPU board installs on the base controller board using the P1 and P3 stack connectors on the solder side of the CPU board. The CPU board can be further secured to the base board with a standoff and screw through the central hole. When a complete PMAC or Turbo PMAC controller is purchased, this assembly is done at the factory. In the case of retrofits or updates to existing controllers, this assembly is easy to do in the field.

WARNING:

The Flex CPU board and PMAC controller boards contain static-sensitive components. Make sure proper ESD protection is employed.

E3 - E6: Servo Clock Frequency Control

OFF OFF OFF OFF N = divided by 16 Note: The setting of I-variable I10 should be adjusted to match the servo interrupt cycle time set by E98, E3 -- E6, E29 -- E33, and the crystal clock frequency. I10 holds the length of a servo interrupt cycle, scaled so that 8,388,608 equals one millisecond. Since I10 has a maximum value of 8,388,607, the servo interrupt cycle time should always be less than a millisecond (unless you want to make your basic unit of time on PMAC something other than a millisecond). If you wish a servo sample time greater than one millisecond, the sampling may be slowed in software with variable Ix60.

Frequency can be checked on J4 pins 21 & 22. It can also be checked from software by typing RX:0 in the PMAC terminal at 10-second intervals and dividing the difference of successive responses by 10000. The resulting number is the approximate Servo Clock frequency kHz.

Note: If E40-E43 are not all on, the phase clock is received from an external source through the J4 serialport connector, and the settings of E3 – E6 are not relevant.

MACHINE CONNECTIONS

Typically, the user connections are actually made to a terminal block that is attached to the JMACH connector by a flat cable (Acc-8D or 8P). The pinout numbers on the terminal block are the same as those on the JMACH connector. The possible choices for breakout boards are the following:

Board Mounting Breakout Style Breakout Connector Notes

Acc-8P DIN – Rail Monolithic Terminal Block Simple Phoenix contact board

Acc-8D DIN – Rail Monolithic Terminal Block

Acc-8DCE DIN – Rail Modular D-sub connector

Acc-8DP Panel Modular D-sub connector Used in the PC-pack product

Mounting

The PMAC 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 PCI socket. If there is a standard PC-style housing, a bracket at the end of the PMAC 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 PMAC PCI board, there are mounting holes that can be

used to mount the board on standoffs.

Headers for connection to option boards Fully shielded for easy CE mark compliance

Power Supplies

Digital Power Supply

2A @ +5V (+/-5%) (10 W) (Eight-channel configuration, with a typical load of encoders)

The host computer provides the 5 Volts power supply in the case PMAC is installed in its internal

•

bus.

With the board plugged into the bus, it will pull +5V power from the bus automatically and it cannot be disconnected. In this case, there must be no external +5V supply or the two supplies will fight each other, possibly causing damage. This voltage could be measured between pins 1 and 3 of the terminal block.

• In a stand-alone configuration, when PMAC is not plugged in a computer bus, it will need an external

five-volt supply to power its digital circuits. The +5V line from the supply should be connected to pin 1 or 2 of the JMACH connector (usually through the terminal block), and the digital ground to pin 3 or 4. Acc-1x provides different options for the 5V power supply.

Analog Power Supply

0.3A @ +12 to +15V (4.5W)

0.25A @ -12 to -15V (3.8W) (Eight-channel configuration)

The analog output circuitry on PMAC is optically isolated from the digital computation circuitry, and so requires a separate power supply. This is brought in on the JMACH connector. The positive supply – +12V to +15V – should be brought in on the A+15V line on pin 59. The negative supply – 12 to -15V – should be brought in on the A-15V line on pin 60. The analog common should be brought in on the AGND line on pin 58.

Machine Connection 27

PMAC-PCI Hardware Reference

Typically, this supply can come from the servo amplifier; many commercial amplifiers provide such a supply. If this is not the case, an external supply may be used. Acc-2x provides different options for the ± 15V power supply. Even with an external supply, the AGND line should be tied to the amplifier common. It is possible to get the power for the analog circuits from the bus, but doing so defeats optical isolation. In this case, no new connections need to be made. However, you should be sure jumpers E85, E87, E88, E89, and E90 are set up for this circumstance. (The card is not shipped from the factory in this configuration.)

Flags Power Supply (optional)

Each channel of PMAC has four dedicated digital inputs on the machine connector: +LIMn, -LIMn (overtravel limits), HMFLn (home flag), and FAULTn (amplifier fault). If the PMAC is ordered with the Option-1 (8-axis PMAC), these inputs can be kept isolated from other circuits. A power supply from 12 to 24V connected on pin 59 of J7 could be used to power the corresponding opto-isolators. In this case, jumper E89 must be removed and jumper E90 must connect pins 1-2.

Overtravel Limits and Home Switches

When assigned for the dedicated uses, these signals provide important safety and accuracy functions. +LIMn and -LIMn are direction-sensitive overtravel limits that must be actively held low (sourcing current from the pins to ground) to permit motion in their direction. The direction sense of +LIMn and LIMn is as follows: +LIMn should be placed at the negative end of travel, and -LIMn should be placed at the positive end of travel.

Resistor Pack Configuration: Flag and Digital Inputs Voltage Selection

The PMAC PCI is provided with 6-pin sockets for SIP resistor packs for the input flag sets. Each PMAC PCI is shipped with no resistor packs installed. If the flag or digital inputs circuits are in the 12V to 24V range, no resistor pack should be installed in these sockets. For flags or digital inputs at 5V levels, quad 1kΩ SIP resistor packs (1KSIP6C) should be installed in these sockets. The following table lists the voltage selection resistor pack sockets for each input device:

Device Resistor Pack Device Resistor Pack

Flags 1 RP77 Flags 5 RP113 Flags 2 RP83 Flags 6 RP119 Flags 3 RP89 Flags 7 RP125 Flags 4 RP94 Flags 8 RP130

Types of Overtravel Limits

PMAC expects a closed-to-ground connection for the limits to not be considered on fault. This arrangement provides a failsafe condition and therefore it cannot be reconfigured differently in PMAC. Usually a passive normally close switch is used. If a proximity switch is needed instead, use a 15V normally closed to ground NPN sinking type sensor.

Jumper E89, E90 and E100 must be set appropriately for the type of sensor used.

28 Machine Connection

PMAC-PCI Hardware Reference

Home Switches

While normally closed-to-ground switches are required for the overtravel limits inputs, the home switches could be either normally close or normally open types. The polarity is determined by the home sequence setup, through the I-variables I902, I907, ... I977. However, for the following reasons, the same type of switches used for overtravel limits are recommended:

Normally closed switches are proven to have greater electrical noise rejection than normally open types. Using the same type of switches for every input flag simplifies maintenance stock and replacements.

Motor Signals Connections (JMACH Connectors)

Resistor Pack Configuration: Termination Resistors

The PMAC 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 PMAC 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 are the type that has independent resistors (no common connection) with each resistor using 2 adjacent pins. The following table shows which packs are used to terminate each input device:

Device Resistor Pack Pack Size Device Resistor Pack Pack Size

Encoder 1 RP61 6-pin Encoder 5 RP98 6-pin Encoder 2 RP63 6-pin Encoder 6 RP100 6-pin Encoder 3 RP67 6-pin Encoder 7 RP104 6-pin Encoder 4 RP69 6-pin Encoder 8 RP106 6-pin

Resistor Pack Configuration: Differential or Single-Ended Encoder Selection

The differential input signal pairs to the PMAC 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 kΩ pull-up resistor to +5V. This cannot be changed.

The ‘-‘ inputs of each differential pair each have a hard-wired 2.2 kΩ resistor to +5V; each also has another 2.2 kΩ 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 kΩ resistors act as a single 1.1 kΩ 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; it is required if complementary open-collector drivers are used; it is permissible for differential line-driver inputs even without encoder loss detection.

Machine Connection 29

PMAC-PCI Hardware Reference

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.

The following table lists the pull-up/pull-down resistor pack for each input device:

Device Resistor Pack Pack Size Device Resistor Pack Pack Size

Incremental Encoder Connection

Each JMACH connector provides two +5V outputs and two logic grounds for powering encoders and other devices. The +5V outputs are on pins 1 and 2; the grounds are on pins 3 and 4. The encoder signal pins are grouped by number: all those numbered 1 (CHA1, CHA1/, CHB1, CHC1, etc.) belong to encoder #1. The encoder number does not have to match the motor number, but usually does. If the PMAC is not plugged into a bus and drawing its +5V and GND from the bus, use these pins to bring in +5V and GND from the power supply. Connect the A and B (quadrature) encoder channels to the appropriate terminal block pins. For encoder 1, the CHA1 is pin 25, CHB1 is pin 21. If using a single-ended signal, leave the complementary signal pins floating – do not ground them. However, if single-ended encoders are used, please check the settings of the jumpers E18 to E21 and E24 to E27. For a differential encoder, connect the complementary signal lines – CHA1/ is pin 27, and CHB1/ is pin 23. The third channel (index pulse) is optional; for encoder 1, CHC1 is pin 17, and CHC1/ is pin 19.

Example: differential quadrature encoder connected to channel #1:

DAC Output Signals

If PMAC is not performing the commutation for the motor, only one analog output channel is required to command the motor. This output channel can be either single-ended or differential, depending on what the amplifier is expecting. For a single-ended command using PMAC channel 1, connect DAC1 (pin 43) to the command input on the amplifier. Connect the amplifier’s command signal return line to PMAC's AGND line (pin 58). In this setup, leave the DAC1/ pin floating; do not ground it.

For a differential command using PMAC Channel 1, connect DAC1 (pin 43) to the plus command input on the amplifier. Connect DAC1/ (pin 45) to the minus-command input on the amplifier. PMAC’s AGND should still be connected to the amplifier common. If the amplifier is expecting separate sign and magnitude signals, connect DAC1 (pin 43) to the magnitude input. Connect AENA1/DIR1 (pin 47) to the sign (direction input). Amplifier signal returns should be connected to AGND (pin 58). This format requires some parameter changes on PMAC; (see Ix25. Jumper E17 controls the polarity of the direction output; this may have to be changed during the polarity test.

30 Machine Connection

PMAC-PCI Hardware Reference

This magnitude-and-direction mode is suited for driving servo amplifiers that expect this type of input, and for driving voltage-to-frequency (V/F) converters, such as PMAC’s Acc-8D Option 2 board, for running stepper motor drivers.

If you are using PMAC to commutate the motor, you will use two analog output channels for the motor. Each output may be single-ended or differential, just as for the DC motor. The two channels must be consecutively numbered, with the lower-numbered channel having an odd number (e.g. you can use DAC1 and DAC2 for a motor, or DAC3 and DAC4, but not DAC2 and DAC3, or DAC2 and DAC4). For our motor #1 example, connect DAC1 (pin 43) and DAC2 (pin 45) to the analog inputs of the amplifier. If using the complements as well, connect DAC1/ (pin 45) and DAC2/ (pin 46) the minus-command inputs; otherwise leave the complementary signal outputs floating. If you need to limit the range of each signal to +/- 5V, you will do so with parameter Ix69. Any analog output not used for dedicated servo purposes may be utilized as a general-purpose analog output. Usually this is done by defining an M-variable to the digital-to-analog-converter register (suggested M-variable definitions M102, M202, etc.), then writing values to the M-variable. The analog outputs are intended to drive high-impedance inputs with no significant current draw. The 220Ω output resistors will keep the current draw lower than 50 mA in all cases and prevent damage to the output circuitry, but any current draw above 10 mA can result in noticeable signal distortion.

Example:

Amplifier Enable Signal (AENAx/DIRn)

Most amplifiers have an enable/disable input that permits complete shutdown of the amplifier regardless of the voltage of the command signal. PMAC’s AENA line is meant for this purpose. If not using a direction and magnitude amplifier or voltage-to-frequency converter, you can use this pin to enable and disable your amplifier (wired to the enable line). AENA1/DIR1 is pin 47. This signal is an opencollector output with a 3.3 kΩ pull-up resistor to +V, which is a voltage selected by jumper E100. The pull-up resistor packs are RP43 for channels 1-4 and RP-56 for motors 5-8. For early tests, you may wish to have this amplifier signal under manual control.

This signal could be either sinking or sourcing as determined by chips U37 and U53 (see jumpers E100E102 and E114-E115). For 24V operation, E100 must connect pins 2-3 and a separate power supply must be brought on pins 9-7 of the J9 JEQU connector. The polarity of the signal is controlled by jumpers E17A to E17H. The default is low-true (conducting) enable. The amplifier enable signal could also be manually controlled setting Ix00=0 and using the suggested definition of the Mx14 variable.

Machine Connection 31

PMAC-PCI Hardware Reference

Amplifier Fault Signal (FAULTn)

This input can take a signal from the amplifier so PMAC knows when the amplifier is having problems, and can shut down action. The polarity is programmable with I-variable Ix25 (I125 for motor #1) and the return signal is analog ground (AGND). FAULT1 is pin 49. With the default setup, this signal must actively be pulled low for a fault condition. In this setup, if nothing is wired into this input, PMAC will consider the motor not to be in a fault condition. The amplifier fault signal could be monitored using the properly defined Mx23 variable.

Some amplifiers share the amplifier fault output with the amplifier enable\disable status output. In this case, a special PLC code must be written with the following sequence: disable the amplifier fault input (see Ix25), enable the motor (J/ command), wait for the amplifier fault input to be false (monitor Mx23), re-enable the amplifier fault input (see Ix25).

General-Purpose Digital Inputs and Outputs (JOPTO Port)

PMAC’s J5 or JOPTO connector provides eight general-purpose digital inputs and eight general-purpose digital outputs. Each input and each output has its own corresponding ground pin in the opposite row. The 34-pin connector was designed for easy interface to OPTO-22 or equivalent optically isolated I/O modules. Delta Tau’s Acc-21F is a six-foot cable for this purpose. Characteristics of the JOPTO port on the PMAC PCI:

• 16 I/O points. 100 mA per channel, up to 24V

• Hardware selectable between sinking and sourcing in groups of eight; default is all sinking (inputs

can be changed simply by moving a jumper; sourcing outputs must be special-ordered or fieldconfigured)

• Eight inputs, eight outputs only; no changes. Parallel (fast) communications to PMAC CPU

• Not opto-isolated; easily connected to Opto-22 (PB16) or similar modules through Acc-21F cable

Jumper E7 controls the configuration of the eight inputs. If it connects pins 1 and 2 (the default setting), the inputs are biased to +5V for the off state, and they must be pulled low for the on state. If E7 connects pins 2 and 3, the inputs are biased to ground for the off state, and must be pulled high for the on state. In either case, a high voltage is interpreted as a '0' by the PMAC software, and a low voltage is interpreted as a 1.

WARNING:

Having Jumpers E1 and E2 set wrong can damage the IC. The +V output on this connector has a 2 A fuse, F1, for excessive current protection.

PMAC is shipped standard with a ULN2803A sinking (open-collector) output IC for the eight outputs. These outputs can sink up to 100 mA and have an internal 3.3 kΩ pull-up resistor to go high (RP18).

32 Machine Connection

PMAC-PCI Hardware Reference

Do not connect these outputs directly to the supply voltage, or damage to the PMAC will result from excessive current draw. The user can provide a high-side voltage (+5 to +24V) into Pin 33 of the JOPTO connector, and allow this to pull up the outputs by connecting pins 1 and 2 of Jumper E1. Jumper E2 must also connect pins 1 and 2 for a ULN2803A sinking output.

It is possible for these outputs to be sourcing drivers by substituting a UDN2981A IC for the ULN2803A. This U13 IC is socketed, and so may easily be replaced. For this driver, the internal resistor packs pulldown instead. With a UDN2981A driver IC, Jumper E1 must connect pins 2 and 3, and Jumper E2 must connect pins 2 and 3.

The outputs can be individually configured to a different output voltage by removing the internal pull-up resistor pack RP18 and connecting to each output a separate external pull-up resistor to the desired voltage level.

Example: Standard configuration using the ULN2803A sinking (open-collector) output IC

Control-Panel Port I/O (JPAN Port)

The J2 (JPAN) connector is a 26-pin connector with dedicated control inputs, dedicated indicator outputs, a quadrature encoder input, and an analog input. The control inputs are low-true with internal pull-up resistors. They have predefined functions unless the control-panel-disable I-variable (I2) has been set to

1. If this is the case, they may be used as general-purpose inputs by assigning M-variable to their corresponding memory-map locations (bits of Y address $FFC0).

Command Inputs

JOG-/, JOG+/, PREJ/ (return to pre-jog position), and HOME/ affect the motor selected by the FDPn/ lines (see below). The ones that affect a coordinate system are STRT/ (run), STEP/, STOP/ (abort), and HOLD/ (feed hold) affect the coordinate system selected by the FDPn/ lines.

Selector Inputs

The four low-true BCD-coded input lines FDP0/ (LSBit), FDP1/, FDP2/, and FDP3/ (MSBit) form a lowtrue BCD-coded nibble that selects the active motor and coordinate system (simultaneously). These are usually controlled from a single 4-bit motor/coordinate-system selector switch. The motor selected with these input lines will respond to the motor-specific inputs. It will also have its position following function turned on (Ix06 is set to 1 automatically); the motor just de-selected has its position following function turned off (Ix06 is set to 0 automatically).

It is not a good idea to change the selector inputs while holding one of the jog inputs low. Releasing the jog input will then not stop the previously selected motor. This can lead to a dangerous situation.

Alternate Use

The discrete inputs can be used for parallel-data servo feedback or master position if I2 has been set to 1. The Acc-39 Handwheel Encoder Interface board provides 8-bit parallel counter data from a quadrature encoder to these inputs. Refer to the Acc-39 manual and Parallel Position Feedback Conversion under Setting up a Motor for more details on processing this data.

Machine Connection 33

PMAC-PCI Hardware Reference

Reset Input

Input INIT/ (reset) affects the entire card. It has the same effect as cycling power or a host $$$ command. It is hard-wired, so it retains its function even if I2 is set to 1.

Handwheel Inputs

The handwheel inputs HWCA and HWCB can be connected to the second encoder counter on PMAC with jumpers E22 and E23. If these jumpers are on, nothing else should be connected to the Encoder 2 inputs. The signal can be interpreted either as quadrature or as pulse (HWCA) and direction (HWCB), depending on the value of I905. I905 also controls the direction sense of this input. Make sure that the Encoder 2 jumper E26 is set for single ended signals, connecting pins 1 and 2.

Optional Voltage to Frequency Converter

The WIPER analog input (0 to +10V on PMAC PCI referenced to digital ground) provides an input to a voltage-to-frequency converter (V/F) with a gain of 25 kHz/Volt, providing a range of 0-250 kHz. The output of the V/F can be connected to the Encoder 4 counter using jumpers E72 and E73. If these jumpers are on, nothing else should be connected to the Encoder 4 inputs. Make sure that the Encoder 4 jumper E24 is set for single-ended signals, connecting pins 1 and 2. This feature requires the ordering of Option-15.

Frequency Decode: When used in this fashion, Encoder 4 must be set up for pulse-and-direction decode by setting I915 to 0 or 4. A value of 4 is usually used, because with CHB4 (direction) unconnected, a positive voltage causes the counter to count up. The encoder conversion table can then take the difference in the counter each servo cycle and scale it, providing a value proportional to frequency, and therefore to the input voltage. Usually this is used for feedrate override (time base control), but the resulting value can be used for any purpose. The resulting value in the default setup can be found at X:$729,24

Power Supply: For the V/F converter to work, PMAC must have +/-12V supply referenced to digital ground. If PMAC is in a bus configuration, this usually comes through the bus connector from the bus power supply. In a standalone configuration, this supply must still be brought through the bus connector (or the supply terminal block), or it must be jumpered over from the analog side with E85, E87, and E88, defeating the optical isolation on the board.

To use this value for feedrate override for a coordinate system, set the time base source address I-Variable (Ix93 for C.S.x.) to 1833 ($729). To use this value for some other purpose, assign an M-Variable to this register (e.g., M60->X:$729,0-24-,U). Scaling is set by the value in Y:$729 (for the default conversion table). This value can be determined interactively by varying the input voltage and noting the effect.

Thumbwheel Multiplexer Port (JTHW Port)

The Thumbwheel Multiplexer Port, or Multiplexer Port, on the JTHW (J3) connector has eight input lines and eight output lines. The output lines can be used to multiplex large numbers of inputs and outputs on the port, and Delta Tau provides accessory boards and software structures (special M-variable definitions) to capitalize on this feature. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in any combination.

The Acc-18 Thumbwheel Multiplexer board provides up to 16 BCD thumbwheel digits or 64 discrete TTL inputs per board. The TWD and TWB forms of M-variables are used for this board. The Acc-34x family Serial I/O Multiplexer boards provide 64 I/O point per board, optically isolated from PMAC. The TWS form of M-variables is used for these boards. The Acc-8D Option 7 Resolver-to-Digital Converter board provides up to four resolver channels whose absolute positions can be read through the thumbwheel port. The TWR form of M-variables is used for this board. The Acc-8D Option 9 Yaskawa Encoder Interface board can connect to up to four of these encoders. The absolute position is read serially through the multiplexer port on power up.

If none of these accessory boards is used, the inputs and outputs on this port may be used as discrete, nonmultiplexed I/O. They map into PMAC’s processor space at Y address $FFC1. The suggested Mvariable definitions for this use are M40 to M47 for the eight outputs, and M50 to M57 for the eight inputs. The Acc-27 Optically Isolated I/O board buffers the I/O in this non-multiplexed form, with each point rated to 24V and 100 mA.

Absolute

Optional Analog Inputs (JANA Port)

The JANA port is present only if Option 12 is ordered for the PMAC PCI. Option 12 provides eight 12bit analog inputs (ANAI00-ANAI07). Option 12A provides eight additional 12-bit analog inputs (ANA08-ANAI15) for a total of 16 inputs. The analog inputs can be used as unipolar inputs in the 0V to +5V range, or bi-polar inputs in the -2.5V to +2.5V range.

The analog-to-digital converters on PMAC require +5V and -12V supplies. These supplies are not isolated from digital +5V circuitry on PMAC. If the PMAC is plugged into the PCI bus, these supplies are taken from the bus power supply. In a standalone application, these supplies must be brought in on terminal block TB1. The -12V and matching +12V supply voltages are available on the J30 connector to supply the analog circuitry providing the signals.

Only one pair of analog-to-digital converter registers is available to the PMAC processor at any given time. The data appears to the processor at address Y:$FFC8. The data from the selected analog input 0 to 7 (ANAI00-ANAI07) appears in the low 12 bits; the data from the selected analog input 8 to 15 (ANAI08-ANAI15) appears in the high 12 bits (this data is only present if Option 12A has been ordered). The input is selected and the conversion is started by writing to this same word address Y:$FFC8. A value of 0 to 7 written into the low 12 bits selects the analog input channel of that number (ANAI00ANAI07) to be converted in unipolar mode (0V to +5V). A value of 0 to 7 written into the high 12 bits selects the analog input channel numbered 8 greater (ANAI08-ANAI15) in unipolar mode. If the value written into either the low 12 bits or the high 12 bits is 8 higher (8 to 15), the same input channel is selected, but the conversion is in bipolar mode (-2.5V to +2.5V).

PMAC variables I60 and I61 allows an automatic conversion of the analog inputs. Setting I60=$FFC8 and I61 with the number of converted registers desired minus 1, the converted data can be found in registers $0708 to $070F. See the PMAC Software Reference for further details on this.

Compare Equal Outputs Port (JEQU Port)

Outputs can be configured sinking or sourcing by replacing the chips U37 or U53 and configuring the jumpers E101-102 or E114-E115. The voltage levels can be individually configured by removing resistor packs RP43 or RP56 and connecting an external pull-up resistor in each output to the desired voltage level.

Serial Port (JRS422 Port)

For serial communications, use a serial cable to connect your PC’s COM port to the PMAC’s J4 serial port connector. Delta Tau provides the Acc-3D cable that connects the PMAC PCI to a DB-25 connector. Standard DB-9-to-DB-25 or DB-25-to-DB-9 adapters may be needed for a particular setup. Jumper E110 selects between RS-232 and RS422 signals type for the J4 connector. If a cable needs to be made, the easiest approach is to use a flat cable prepared with flat-cable type connectors as indicated in the following diagram:

The JTHW multiplexer port provides eight inputs and eight outputs at TTL levels. While these I/O can be used in un-multiplexed form for 16 discrete I/O points, most users will utilize PMAC software and accessories to use this port in multiplexed form to greatly multiply the number of I/O that can be accessed on this port. In multiplexed form, some of the SELn outputs are used to select which of the multiplexed I/O are to be accessed.

The J7 connector is used to connect the PMAC to the second 4 channels (Channels 5, 6, 7, and 8) of servo amps, flags, and encoders.

Note 1: In standalone applications, these lines can be used as +5V power supply inputs to power PMAC's digital circuitry. However, if a terminal block is available on your version of PMAC, it is preferable to bring the +5V power in through the terminal block.

Note 2: Referenced to digital common (GND). Maximum of + complement.

Note 3: Leave this input floating if not used (i.e. digital single-ended encoders). In this case, jumper (E18

- 21, E24 - 27) for channel should hold input at 2.5V.

Note 4: +

Note 5: Leave floating if not used; do not tie to AGND. In this case, AGND is the return line.

Note 6: Functional polarity controlled by jumper(s) E17. Choice between AENA and DIR use controlled

by Ix02 and Ix25.

Note 7: Functional polarity controlled by variable Ix25. Must be conducting to 0V (usually AGND) to produce a '0' in PMAC software. Automatic fault function can be disabled with Ix25.

Note 8: Pins marked -LIMn should be connected to switches at the positive end of travel. Pins marked +LIMn should be connected to switches at the negative end of travel.

Note 9: Must be conducting to 0V (usually AGND) for PMAC to consider itself not into this limit. Automatic limit function can be disabled with Ix25.

Note 10: Functional polarity for homing or other trigger use of HMFLn controlled by Encoder/Flag Variable 2 (I902, I907, etc.) HMFLn selected for trigger by Encoder/Flag Variable 3 (I903, I908, etc.). Must be conducting to 0V (usually AGND) to produce a 0 in PMAC software.

SOFTWARE SETUP

Communications

Delta Tau provides communication tools that take advantage of the PCI bus Plug and Play feature of 32bits Windows 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 boot 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 or the resources page of the device manager.

PMAC I-Variables

PMAC has a large set of Initialization parameters (I-variables) that determine the personality of the card for a specific application. Many of these are used to configure a motor properly. Once set up, these variables may be stored in non-volatile EAROM memory (using the SAVE command) so the card is always configured properly (PMAC loads the EAROM I-variable values into RAM on power-up).

The easiest way to program, setup and troubleshoot PMAC is by using the PMAC Executive Program Pewin and its related add-on packages P1Setup and PMAC Plot. These software packages are available from Delta Tau, ordered through Acc-9WN.

The programming features and configuration variables for the PMAC PCI are fully described in the PMAC User and Software manuals.

based computers. Starting with MOTIONEXE.EXE version 10.32.00, which is included

Operation of the Non-Turbo CPU

When used as a non-Turbo CPU, the Flex CPU board operates in a manner that is fundamentally compatible with older CPU designs. However, there are a few issues to note:

• The Flex CPU requires the use of V1.17 or newer firmware. There are few differences between the previous V1.16H firmware and the V1.17 firmware other than the addition of internal support for the Flex CPU design.

• Due to more advanced processor logic and the internal integration of all memory, the Flex CPU will operate significantly faster than older non-Turbo CPU designs, even for equivalent CPU frequencies. The Flex CPU in a non-Turbo configuration will generally operate more than twice as fast as older non-Turbo CPUs running at the same frequency.

This will result in significantly faster cycle times for background tasks such as PLC programs (the frequency of interrupt-driven foreground tasks is not affected, although the increased computational speeds permit higher frequencies for these tasks). Generally, this will not be a problem, but if existing programs controlled timing by computational delay (e.g. number of loops waiting), operational differences may occur.

• The operational frequency of the CPU can now be set in software by new variable I46. If this variable is set to 0, PMAC firmware looks at the jumpers (E48 on a PMAC(1), E2 and E4 on a PMAC2) to set the operational frequency, retaining backward compatibility for 40, 60, and 80 MHz operation.. If I46 is set to a value greater than 0, the operational frequency is set to 10MHz * (I46 + 1), regardless of the jumper setting. If the desired operational frequency is higher than the maximum rated frequency for that CPU, the operational frequency will be reduced to the rated maximum. It is always possible to operate the Flex CPU board at a frequency below its rated maximum.

On a Flex CPU board configured for Option 5AF with 40 MHz maximum frequency, I46 should be set to 3 to operate the CPU at its maximum rated frequency.

Software Setup 55

PMAC-PCI Hardware Reference

On a Flex CPU board configured for Option 5CF with 80 MHz maximum frequency, I46 should be set to 7 to operate the CPU at its maximum rated frequency.

On a Flex CPU board configured for Option 5EF with 160 MHz maximum frequency, I46 should be set to 15 to operate the CPU at its maximum rated frequency.

I46 is only used at power-up/reset, so to change the operational frequency, set a new value of I46, issue a SAVE command to store this value in non-volatile flash memory, then issue a $$$ command to reset the controller.

To determine the frequency at which the CPU is actually operating, issue the TYPE command to the PMAC. The PMAC will respond with five data items, the last of which is “CLK Xn”, where “n” is the multiplication factor from the 20 MHz crystal frequency (not 10 MHz). “n” should be equivalent to (I46+1)/2 if I46 is not requesting a frequency greater than the maximum rated for that CPU board. “n” will be “2” for 40 MHz operation, “4” for 80 MHz operation, and “8” for 160 MHz operation.

• If the CPU’s operational frequency has been determined by (a non-zero setting of) I46, the serial communications baud rate is determined at power-up/reset by variable I54 alone according to the following table:

I54 Baud Rate I54 Baud Rate

0 600 8 9600

1 900 9 14,400

2 1200 10 19,200

3 1800 11 28,800

4 2400 12 38,400

5 3600 13 57,600

6 4800 14 76,800

7 7200 15 115,200

Note that these values can be different from those used on PMAC2 boards with jumper-set CPU frequencies (see below).

56 Software Setup

PMAC-PCI Hardware Reference

• If the saved value of I46 is 0, so the CPU’s operational frequency is determined by jumper settings, then the serial baud rate is determined by a combination of the setting of jumpers E44E47 and the CPU frequency on a PMAC(1) board, as shown in the following table. These settings maintain backward compatibility.

* Not an exact baud rate

• With the Flex CPU, the card number (0 – 15) for serial addressing of multiple cards on a daisychain serial cable is determined by variable I0, even on PMAC(1) boards. This has always been the case for PMAC2 boards, but with other CPU boards, the card number on PMAC(1) boards has been determined by the settings of jumpers E40 – E43. Jumpers E40 – E43 on a PMAC(1) board with the Flex CPU still determine the “direction” of the phase and servo clocks: all of these jumpers must be ON for the card to use its internally generated clock signals and to output these on the serial port connector; if any of these jumpers is OFF, the card will expect to input these clock signals from the serial port connector, and its watchdog timer will trip immediately if it does not receive these signals.

Configuring PMAC with Option-5C for 80 MHz Operation

On a PMAC with flash-backed main memory, jumper E48 controls the frequency of operation of the DSP. It can only directly set 40 MHz and 60 MHz DSP operation. On power-up/reset, the DSP, operating at the crystal frequency of 20 MHz, reads the frequency jumper E48 and writes into its own PLL multiplier register at X:$FFFD. Bits 0-3 of this word contain a value one less than the multiplier value (if the frequency is being multiplied by 3, these bits contain a value of 2).

58 Software Setup

PMAC-PCI Hardware Reference

To check the value of the multiplier, use the on-line command RHX:$FFFD and look at the last hexadecimal digit. The actual multiplier is one greater than the value in this last digit. Alternately, define an M-variable such as M99->X:$FFFD,0,4 and then read from or write to these bits with the M-variable.

E48 X:$FFFD; 0-3 True Multiplier DSP Frequency

OFF 1 x2 40 MHz

ON 2 x3 60 MHz

When PMAC is ordered with the CPU Option 5C it is capable to run at 80 MHz frequency. To operate the CPU at 80 MHz, set the multiplier value in user software. In this case, usually E48 will be set OFF, so the CPU comes up at 40 MHz. The usual way to set the multiplier value for 80 MHz is to use a reset PLC, one that executes automatically on power-up/reset, then disables itself. Typically, this is PLC 1, the first to execute after power-up/reset (see below).

If using serial communications on an 80 MHz PMAC, change the baud rate divider register in the CPU. On power-up/reset, the firmware reads jumpers E44-E47 and sets the baud rate divider register in the CPU (at X:$FFF2 bits 0 to 11) to set the serial baud rate. Since the baud rate clock is derived from the CPU frequency, a change in the CPU frequency will change the baud rate.

To counteract this change, when the CPU frequency is changed, change the baud rate divider register in the CPU. If the CPU frequency is doubled, double the divider value and add 1. This should be done in the reset PLC also.

This operation can be done with the following code segment. This baud divider algorithm is valid only if the PMAC has been jumpered for 40 MHz operation (E48 OFF).

M98->X:$FFF2,0,12 M99->X:$FFFD,0,4

OPEN PLC 1 CLEAR M99=3 ; Set x4 frequency multiplication (80 MHz) M98=2*M98+1 ; Increase baud divider to maintain rate

; (Only needed for serial communications) more of reset PLC

DISABLE PLC 1 ; So PLC 1 will not repeat CLOSE

To make the change in CPU frequency and baud rate over the serial port with on-line commands, make sure that the two commands are on the same command line. If they are on separate command lines, the second command will not be accepted because the baud rate has changed. For example, with the same setup as the above example, use the command line

M99=3 M98=2*M98+1

to change the CPU frequency and baud rate divider (to keep the baud rate constant) together.

Option 16 Supplemental Memory

If the Option 16 supplemental battery-backed parameter memory is ordered, an extra bank of memory with battery backup circuitry is provided. This option can only be ordered if the main memory is flash backed (Option 4A, 5A, 5B, or 5C). This memory is for user parameter storage only. From PMAC programs, it can be accessed with M-variables only (L-variables also in compiled PLCs). The on-line direct-memory read and write commands can be used from the host computer as well.

With M-variable access, arrays can be created with indirect addressing techniques by pointing a second M-variable to the definition of a first M-variable that points into this memory area. For example, with the M-variable definitions:

M0->L:$A000 ; 1st long word of Opt. 16 RAM; floating point M10->Y:$BC000,0,16 ; Low 16 bits of M0 def., with pointer address

The following code segment could load a sine table into the first 360 words of the Option 16 RAM:

Software Setup 59

PMAC-PCI Hardware Reference

P1=0 WHILE (P1<360) M10=$A000+P1 ; Sets address that M0 points to M0=SIN(P1) ; Puts value in register that M0 points to P1=P1+1 ENDWHILE

Note that this technique is not possible with L-variables in compiled PLCs (but it is possible with Mvariables in compiled PLCs).

Physically, the Option 16 memory is a 16k x 24 bank of battery-backed static RAM. It maps into the PMAC and PMAC2 at addresses $A000 to $BFFF, on both the X and Y data buses, an 8k x 48 block of address space. Addresses Y:$BC00 to Y:$BFFF are “double-mapped” with the main flash-backed RAM for the M-variable definitions, and should not be used for user parameter storage.

Any value written into the Option 16 memory will automatically be retained through a power-down or reset; no SAVE operation is required. The power draw on the battery is low enough that battery life will typically be limited only by the quoted 10-year life of the battery.
