The ACR8000 is a floating point DSP-based 8 axis motion controller. It has onboard hardware to read up to eight incremental encoders and supply precision 16-bit analog for eight servo amplifiers. It is modular in nature and is offered in 2, 4, 6 or 8 axis configurations. This board will work in standalone mode as well as within a PC-AT bus chassis. In the PC-AT bus, the board takes one and one half slots. Introduction 1 This page intentionally left blank. 2 ACR8000 Hardware Manual P/N PM08119 Version 1.00 CHAPTER 1 Hardware Installation Chapter 1, Hardware Installation 3 This page intentionally left blank. 4 ACR8000 Hardware Manual P/N PM08119 Version 1.00 Chapter Overview Description: This chapter contains diagrams of the jumpers and connectors on the ACR8000 mother and daughter boards. Before optically isolated digital inputs and outputs can be used, the card must be connected to an external 24 volt DC power supply. This connection is made at the PWR1 connector and is fused onboard at 3 amps to protect the controller card. Encoder pull-up jumpers must be set correctly based on the types of encoders being used. Failure to set these jumpers correctly may cause damage to the encoders or to the receivers on the controller card. There are no analog adjustment "pots" on the board. All analog gain and offset is under software control. The analog outputs must be wired to differential control signal inputs on a servo amplifier. The outputs provide an analog control voltage of ±10 volts. Stepper simm module outputs provide open-collector step and direction signals. There are no pull-up resistors provided on the Stepper outputs. Factory default jumper settings for the Acr8000 mother and daughter boards are highlighted within the following jumper tables. Chapter 1, Hardware Installation 5 Motherboard Jumpers Address Select (SW1) Figure 1.1 Address select switch The ACR8000 can receive and transmit data through I/O ports on a PC BUS. The addresses of these ports are selectable using SW1 on the ACR8000 motherboard. The data port is used to both transmit and receive. Both the transmit and receive channels are connected to 512 byte First In / First Out (FIFO) hardware buffers. The status port is used to see if data is waiting to be received from the card and if it is OK to send data to the card. The byte read from the status port is defined as follows: BIT Definition Description BIT7 Transmit Not Full Clear to send one byte BIT6 Transmit Not Half Full Clear to send up to 255 bytes BIT5 Receive Not Empty Data available BIT4 Transmit Not Empty Still something in the buffer Table 1.1 PC BUS status port bits 6 ACR8000 Hardware Manual P/N PM08119 Version 1.00 Motherboard Jumpers Address Select (continued) The following table shows how the switch positions relate to the ACR8000 card number and I/O port addresses. Note that switches SW1-1 through SW1-5 are reserved and should be left in the OFF position. Card SW1 Settings Addresses Number 6 7 8 Data Status 0 OFF OFF OFF 0x300 0x302 1 OFF OFF ON 0x304 0x306 2 OFF ON OFF 0x308 0x30A 3 OFF ON ON 0x30C 0x30E 4 ON OFF OFF 0x310 0x312 5 ON OFF ON 0x314 0x316 6 ON ON OFF 0x318 0x31A 7 ON ON ON 0x31C 0x31E Table 1.2 PC BUS port addresses Chapter 1, Hardware Installation 7 Motherboard Jumpers Serial Port Select (JS1, JS2) Figure 1.2 Serial port jumpers COM1 COM2 JS1 JS2 RS232 RS232 1-2 1-2 RS232 RS422 1-2 2-3 RS422 RS232 2-3 1-2 RS422 RS422 2-3 2-3 Table 1.3 Serial port jumpers In addition to the above jumper settings, the proper hardware option for RS-232 or RS-422 communications must be purchased and installed. The serial communication ports have an automatic baud rate detection feature. Hitting ENTER key a few times from a dumb terminal or sending several CHR$(13) characters from a serial host will wake up the communications port. 8 ACR8000 Hardware Manual P/N PM08119 Version 1.00 Motherboard Jumpers Interrupt Select (JS3) Figure 1.3 PC BUS interrupt jumper The ACR8000 can be instructed to interrupt a PC host through the parallel bus by issuing a SET 112 command in immediate mode or from within a program. Interrupt driven software at the host level is an advanced topic and should only be attempted by someone with a thorough knowledge of interrupt driven code. In order for the PC to see the interrupt, the proper jumper selection from the following table must be made. IRQ5 is usually a good choice since printer code seldom uses interrupts and use of the secondary printer port (LPT2) is even rarer. Level JS3 Common Function Disabled 1-3 Not Applicable IRQ3 1-2 Secondary Serial (COM2) IRQ4 3-4 Primary Serial (COM1) IRQ5 5-6 Secondary Parallel (LPT2) IRQ7 7-8 Primary Parallel (LPT1) IRQ10 9-10 Reserved (unused) IRQ11 11-12 Reserved (unused) IRQ12 13-14 Reserved (unused) IRQ15 15-16 Reserved (unused) Table 1.4 PC BUS interrupt jumper IMPORTANT NOTE: When the ACR8000 is used in a Pentium processor based PCI motherboard, the selected interrupt must be configured in the PCI motherboard BIOS as a Legacy ISA interrupt (or Used By ISA in some BIOS’), since the ACR8000 is an ISA board. Chapter 1, Hardware Installation 9 Motherboard Jumpers Encoder Pull-up Select (JS21..JS28) Figure 1.4 Encoder pull-up jumpers The ACR8000 is capable of handling various types of incremental open-collector and line driver encoders. Care must be taken to setup each channel to match the encoder type as described below: Open Collector Encoders: When using open-collector encoders, the encoder channels must be pulled to either +5 or +12 volts, depending on the application. Pulling up to +12 volts provides higher noise immunity but causes a slower response time. For high frequency applications (encoder rates greater than one megahertz) the +5 volt pull-up selection may be necessary. 10 ACR8000 Hardware Manual P/N PM08119 Version 1.00 Motherboard Jumpers Encoder Pull-up Select (continued) Line Driver Encoders: When using line driver (or balanced pair) encoders, the corresponding resistor pack should be removed from its socket. Leaving the resistor pack in can cause faulty encoder operation and possibly cause severe encoder damage. It does not matter what pull-up voltage is selected when the resistor pack is removed. Optionally, the resistor pack can be replaced with an 8-pin isolated resistor pack to supply termination resistance for the balanced signal pairs. Pull-up selection: The following table lists the pull-up jumper settings for each encoder: ENC Resistor Jumper +5V +12V � WARNING 0 RP1 JS21 1-2 *2-3 1 RP2 JS22 1-2 *2-3 Wiring a line driver 2 RP3 JS23 1-2 *2-3 encoder with the pull-up selected to 3 RP4 JS24 1-2 *2-3 +12 volts will permanently 4 RP5 JS25 1-2 *2-3 damage the encoder. 5 RP6 JS26 1-2 *2-3 6 RP7 JS27 1-2 *2-3 7 RP8 JS28 1-2 *2-3 Table 1.5 Encoder pull-up jumpers Chapter 1, Hardware Installation 11 Motherboard Connectors Encoder Inputs (P1A, P1B) Figure 1.5 Encoder input connectors 12 ACR8000 Hardware Manual P/N PM08119 Version 1.00 Motherboard Connectors Encoder Inputs (P1A, P1B), Cont’d Note: P1A and P1B are 34-pin shrouded male headers.
