ADLINK MNET-4XMO/C Distributed Motion Module Installation and Debugging Guide

ADLINK MNET-4XMO and MNET-4XMO-C are 4-axis slave modules designed for Motionnet distributed motion control systems. They are based on ASIC motion control cores and support up to 9.9 MHz pulse output and 20 MHz encoder feedback (4 × AB mode). They provide linear/S-curve acceleration and deceleration, 2-4 axis linear interpolation, 2-axis arc interpolation, 13 zeroing modes, and rich servo interface signals (SVON, INP, ALM, ERC, etc.). The MNET-4XMO-C model additionally integrates high-speed position comparison and trigger output functions (up to 1 MHz single axis trigger or 100 kHz four axis trigger), suitable for scenarios such as AOI detection, aerial positioning, and continuous path motion. This article is based on the user manual, systematically reviewing hardware installation, dip switch configuration, signal wiring, motion mode selection, continuous triggering and path movement function applications, as well as the use of MotionCreatorPro 2 debugging tool to help motion control engineers quickly complete on-site deployment and troubleshooting.

Product positioning and model differences

MNET-4XMO is a universal 4-axis pulse motion control module that communicates with the main station (such as PCI-7856 or DB-8153) through Motionnet high-speed serial bus (20 Mbps). A single main station can mount up to 64 modules (with a total of 256 axes). Its core motion functions are implemented by the NPM PCL6046 series ASIC, including:

32-bit instruction/feedback counter, 16 bit acceleration/deceleration time setting

Position/velocity coverage (on the fly change)

Triangle speed automatic suppression (small stroke automatic deceleration)

Vibration suppression (reducing mechanical oscillation during pauses)

MNET-4XMO-C adds:

5 32-bit comparators per axis (20 in total), supporting position comparison triggering

Table mode (8192 preset points per axis) and linear mode (start+step+number of times)

Ultra high speed trigger channel (only for the first axis, 1 MHz)

Path Move function: up to 2048 points, supports continuous speed automatic connection

Fast Index Move: Pre stored motion parameters, quickly launched only through index numbers

Selection suggestion: If only basic point motion and interpolation are needed, the standard version is sufficient; If you need to trigger the camera or perform aerial photography, you must choose the C model.

Hardware installation and switch settings

2.1 Module Layout and Interfaces

The main interfaces of the module include:

J8: External 24V power input (E24V), I/O common terminal (DICOM), emergency stop input (EMG)

HS1/HS2: RJ-45 sports network cascade port (4/5 pins are DATA -/DATA+)

CN1: Differential output of brake signals (Brake1-4)

IOIF1~IOIF4: Mechanical I/O and GPIO (including PEL, MEL, ORG, DI/DO, CMP ±, etc.)

CM1~CM4: Servo interface (including OUT ±/DIR ± differential pulse, EA ±/EB ±/EZ ± encoder feedback, SVON, INP, ALM, ERC, RDY, EMG, etc.)

2.2 Key dialing and jumper settings (S1~S7, JP4~JP6)

Correctly configuring the following switches is a prerequisite for stable system operation:

Switch Function Description

S1 slave station ID setting binary dialing code, range 0~63, must be unique within the same master station

S2 communication rate can be selected as 2.5/5/10/20 MHz, it is recommended to be consistent with the main station and slow down over long distances

When the S3/S5 reset servo alarm signal is enabled ON, the DO signal of IOIF is connected to the RST pin of CM for automatic reset of the driver alarm

If the S6 terminal resistor (TMR) and TUD module are located at the end of the Motionnet line, TMR (120 Ω) needs to be enabled; TUD is a pull-up/pull-down setting, usually kept as default

S7 FGND grounding selection connects the shielding layers of CM1~4 to the chassis ground (FGND) to improve anti-interference

If the JP4 EMG signal is short circuited, the EMG input will take effect. Otherwise, it will be disabled (use with caution)

JP5/JP6 power mode selection: whether E24V (module power supply) and I24V (I/O power supply) are shared. If the external I/O is isolated from the module power supply, it is set as "different power supply"; If the same 24V source is shared, it is short circuited as' shared '.

2.3 Wiring precautions

Differential pulse output (OUT ±/DIR ±): driven by 26LS31, the single ended ground current should not exceed 20mA, otherwise the chip will be damaged. Recommend using OUT - and DIR - to connect drivers (see manual diagram).

Encoder feedback (EA ±/EB ±/EZ ±): differential input, common mode voltage ± 7V. The longest cable depends on the frequency, and it is recommended to use twisted pair shielded wires with a single end grounded shield layer.

Emergency stop (EMG): using B-type (normally closed) contacts, 24V/6mA or above, with software configurable polarity.

Limit/Origin (PEL/MEL/ORG): Switch capacity 24V/6mA, can be set to normally open or normally closed by software.
