ADLINK PCI-8134 Motion Control Card Deployment Guide

ADLINK PCI-8134 Four Axis Motion Control Card Deployment and Programming Complete Guide

In the field of industrial automation, the stability and flexibility of motion control systems directly affect equipment accuracy and production efficiency. ADLINK's PCI-8134 is a 4-axis servo/stepper motion control card based on the PCI bus. It adopts a dual ASIC (PCL5023) architecture and supports up to 2.4 Mpps pulse output, trapezoidal/S-shaped curve velocity curve, 2-axis linear/arc interpolation, incremental encoder feedback, and rich I/O interfaces. It is suitable for applications such as dispensing, cutting, XY platform, and robotic arm. This article provides a complete deployment and development reference for motion control system engineers from hardware installation, signal wiring, software configuration, function library calling to debugging and troubleshooting.

Overview of Card Board and Hardware Installation

PCI-8134 is a semi long PCI card with dimensions of 164 × 98.4 mm, compliant with PCI 2.1 specifications, and supports plug and play. Two PCL5023 motion control ASICs are integrated on the board, each controlling two axes, for a total of four axes. The main technical indicators include:

Pulse output frequency: 0~2.4 Mpps

Position counter: 28 bits (0~268435455 or ± 134217728)

Acceleration/deceleration setting: 1~65535 (16 bits)

Internal reference clock: 9.8304 MHz

External power supply:+24V DC ± 5%, 500mA (for I/O isolation)

Connectors: 100 pin SCSI-II (CN2), as well as CN1 (power supply), CN3 (handwheel), CN4 (synchronous start stop)

Installation steps:

Turn off the PC power and remove the chassis cover.

Select an available 32-bit PCI slot (white or ivory), insert and secure the card.

Connect the CN1 external+24V power supply (with accompanying power cord) and make sure to confirm the polarity.

If you need to connect the handwheel or synchronization signal, connect CN3/CN4 as needed.

After power on, the system BIOS automatically assigns I/O addresses and IRQs without the need for manual jumpers (only J1-J8 are used for pulse output mode selection, S1 is used for limit switch type).

Attention: If the system fails to start or runs abnormally, it may be caused by interrupt conflicts. It is necessary to check the PCI IRQ allocation in the BIOS or disable onboard serial and parallel ports to release resources.

Signal connection and interface configuration

CN2 is the main connector, which includes pulse output for all axes, encoder feedback, limit, origin, deceleration, servo interface, and universal I/O. The following is a detailed explanation of each key signal.

2.1 Pulse output (OUT ±, DIR ±)

Each axis has a pair of differential outputs (OUT+/- and DIR+/-), which can be configured in two modes:

Single pulse mode (OUT/DIR): OUT outputs pulses, DIR level indicates direction.

Dual pulse mode (CW/CCW): OUT is the forward pulse and DIR is the reverse pulse.

Select differential drive (default) or open set output through jumper J1~J8. In open mode, OUT - and DIR - output signals, with a current not exceeding 20mA, need to be externally pulled up to EX+5V (maximum 500mA).

Wiring example:

Differential drive: PULS+/PULS -, SIGN+/SIGN - directly connected to servo drives (such as Panasonic, Yaskawa).

Open set output: A current limiting resistor needs to be connected in series with the signal line (if an external power supply is used).

2.2 Encoder feedback (EA ±, EB ±, EZ ±)

Three pairs of differential inputs, supporting AB phase (1X/2X/4X) or CW/CCW modes. The input circuit requires a differential voltage of ≥ 3.5V and a driving current of ≥ 6mA. If the encoder has an open set output, an external pull-up resistor and power supply (refer to the recommended values in the manual) are required. The EZ signal (Z-phase) is used for precise indexing when returning to the origin.

2.3 Limit, deceleration and origin

PEL/MEL: Positive/negative direction limit switch, immediately stops pulse output upon triggering (and clears servo deviation counter).

PSD/MSD: Positive/negative deceleration switch, triggered to reduce the speed to the preset starting speed, used for early deceleration when approaching the limit.

ORG: Origin switch, used for returning to origin mode. It can be configured to stop only when ORG is triggered, or wait for EZ signal after ORG is triggered before stopping.

The above switches all use a+24V source with an input current of 6mA (internal optocoupler isolation). When wiring, it is necessary to ensure that the switch contact capacity is sufficient. S1 dip switch is used to select the type of limit switch: default OFF is normally open (contact A), ON is normally closed (contact B).

2.4 Servo interfaces (INP, ALM, ERC, SVON, RDY)

INP (In Place Signal): The servo drive deviation counter outputs zero and can be used to delay motion completion judgment.

ALM (Alarm Signal): Triggered in case of servo failure, configurable to immediately stop or decelerate to stop.

ERC (Deviation Counter Reset): Automatically outputs a 10ms pulse to clear servo position error when returning to the origin, triggering limit, alarm, or software emergency stop.

SVON (Universal Output): Can control servo enable.
