Chapter 2 Hardware Installation, Jumper and Interface Definition

1. Packing list

PCI-8132 motherboard, 100 core SCSI cable, 24V power supply terminal wire, user manual, driver CD.

PCI is plug and play, and BIOS automatically assigns base addresses and IRQs without the need for dialing;

Troubleshooting: Black screen/device conflict during startup, enter BIOS to adjust PCI interrupt allocation.

3. Three major connector functions

CN1: External 24V power terminal

Connect external DC24V to the isolated IO circuit, and the onboard DC-DC output 5V external power supply must be connected to 24V, otherwise the IO cannot work.

CN2: 100 core SCSI main interface (all motion, encoder, universal IO)

Divided into two sets of axis signals (axis 0/axis 1), 16DI, 16DO, handwheel PA/PB, CMP trigger, external 5V/24V power output, the manual provides a complete pin definition table.

CN3: Synchronous start stop terminal

STA synchronization starts, ST synchronization stops, and multi card CN3 is cascaded with each other to achieve global synchronous motion; Comes with PCI 5V pull-up.

Chapter 3: Instructions for All Signal Wiring

Explain the electrical characteristics and differential/collector wiring schemes of each signal category by category, including circuit diagrams:

Pulse output OUT/DIR

Differential drive output (default), compatible with collector mode; Maximum current of 20mA; switch between two pulse logic software.

Encoder EA/EB/EZ

Differential input, compatible with external collector encoders (requires series current limiting resistors: 5V without resistance, 12V series 1.8k, 24V series 4.3k); Supports 4x counting.

Limit/Origin (PEL/MEL/PSD/MSD/ORG)

24V input, built-in filtering and stabilization; The SD deceleration signal triggers automatic deceleration to the starting speed, and the EL hard limit immediately stops pulse output.

Servo specific signal

INP: Servo in place signal, can be software enabled to wait for in place before determining the completion of the motion;

ALM: Driver alarm triggers immediate deceleration/emergency stop, resulting in interruption;

ERC: Deviation reset, automatically output 100ms pulse when returning to zero/limit/alarm/emergency stop, clear servo deviation counter;

Chapter 4 Working Principle of Motion Control (Core Motion Algorithm)

1. Seven major sports operation modes

Constant speed motion

Trapezoidal and S-type acceleration. During operation, call _8132_v_change to modify the maximum speed in real time, and support dynamic speed regulation.

Point motion (trapezoidal curve)

Absolute coordinate a_move, relative coordinate r_move; Support symmetric/asymmetric acceleration and deceleration; When the travel is insufficient, it automatically switches to a triangular curve without shaking.

S-curve point motion

Segmented S acceleration and deceleration (S acceleration section+linear acceleration section), reducing mechanical impact and extending equipment life; The parameter includes the duration of S acceleration/deceleration.

Two axis linear interpolation

X/Y synchronous start stop, allocate speed of each axis according to distance, support composite vector speed, used for planar straight line machining.

Zero Return to Origin (3 Modes)

Mode 0: Stop at ORG origin only;

Mode 1: Trigger ORG and quickly search for EZ index before stopping;

Mode 2: ORG triggers deceleration, searching for EZ index at low speed (high-precision zeroing);

Can latch ORG signal to prevent short pulse loss.

Hand wheel manual mode

PA/PB reading handwheel pulse, 1/2/4 harmonics optional, limiting maximum following speed; Support single wheel control for dual axis.

Multi card synchronous motion

CN3 cascade+_8132umove_all function, all axes start and arrive simultaneously.

2. Servo IO, limit, encoder logic

INP/ALM logic programmable, capable of setting alarms for immediate shutdown or deceleration shutdown;

SD deceleration signal, EL hard limit software enable/disable, customizable high and low level effectiveness;

Encoder counting source switching: internal instruction pulse/external grating feedback, used for fully closed-loop platforms.

Support 1024 point array tables and linear interval point generation functions;

Output hardware pulses and optional interrupts during matching, without the need for real-time polling by the upper computer.

4. Interrupt system

13 types of configurable interrupt sources: limit trigger, zero return completion, point in place, encoder error, CMP matching, abnormal handwheel, etc; DOS provides interrupt service programs, while Windows handles interrupts through thread events.
