Technological Innovation | MT Launches M900 Modular Multi-Axis Bus Servo, Ushering in a New Era of Modular Multi-Axis Servo Drives

MT keeps advancing iterative upgrades of modular multi-axis servo technology and pushing the boundaries of motion control performance. Following the ground-breaking first-generation M620 and system-optimized second-generation M800, MT has accumulated two generations of technical expertise and verified performance through extensive real-world deployments. Today, we officially release the third-generation modular multi-axis bus servo series — the M900 Series. As a milestone product marking our technological evolution, the M900 delivers architecture-level innovation to break the limitations of conventional standalone servo drives. It achieves all-round breakthroughs in integration capacity, operational performance, energy efficiency and intelligent maintenance, signaling a brand-new iteration phase for modular multi-axis servo technology.

In response to industrial trends toward compact integration, high-speed high-precision operation, flexible production and low-carbon energy conservation for premium automation equipment, the M900 features a systematic overhaul of its underlying architecture. Compatible with rotary motors, DD motors and linear motors, and supporting mainstream industrial bus protocols, the M900 fully adapts to complex working conditions across high-end precision manufacturing, new energy and intelligent equipment sectors. It delivers a brand-new multi-axis motion control solution to facilitate digital, flexible and low-carbon factory transformation.

Powered by a brand-new technical framework, the M900 incorporates eight core technological innovations to systematically resolve long-standing industry pain points of traditional multi-axis servos, including redundant cabinet space, cumbersome maintenance, excessive energy consumption and inefficient commissioning:

1. Upgraded High-Precision & High-Speed Performance for Premium Precision Applications

The M900 Series features a 125 μs communication refresh cycle and 3.8 kHz speed loop bandwidth, with built-in gantry synchronization boasting an internal control cycle of 62.5 μs. Optimized for high-speed, ultra-precise motion control scenarios, it drastically cuts system response latency and boosts equipment performance and productivity.

2. Fully Modular Architecture Enables Tool-Free Ultra-Fast Maintenance

Departing from conventional standalone servo designs, the M900 adopts a fully modular technical route for superior flexibility and expandability. Its patented modular assembly structure enables fast screw-free electrical assembly and tool-free hot-swappable module replacement on site. After module replacement, all parameters restore automatically; the system can start up directly after power-on without professional configuration, greatly streamlining maintenance and lowering technical barriers for service personnel.

3. Ultra-High Power Density Drastically Reduces Equipment Footprint

Compared with traditional standalone servo systems, the M900 delivers exceptional integration and space utilization with industry-leading power density. Each single drive module supports up to 3 axes, while one power supply module can accommodate a maximum of 15 axes. A 6-axis setup cuts cabinet space by 50%, and a 15-axis system saves up to 70% space. A complete 6-axis unit fits within an A4-sized footprint, maximizing cabinet utilization efficiency.

4. Streamlined Structure Cuts Overall Installation Costs

Thanks to high integration, the M900 enables miniaturized electrical cabinets, slashing cabinet space and related costs by 50%–70%. It eliminates a large number of peripheral components including cables, battery boxes, braking resistors and intermediate relays to reduce accessory expenses. Field wiring and assembly labor hours are lowered by over 50%, accelerating cabinet assembly and trimming overall installation expenditure.

5. Comprehensive Multi-Layer Safety Protection Ensures Stable Equipment Operation

The M900 integrates multiple safety mechanisms including STO (Safe Torque Off), linked fault alarms, external emergency stop, dynamic braking and a black box data recorder to fully safeguard equipment and workpieces. The black box function enables efficient analysis of process control and motion process defects, supporting fault diagnosis for unattended production lines and sporadic abnormal failures.

6. Common DC Bus Architecture Reduces Energy Consumption & Boosts Productivity

The proprietary common DC bus architecture eliminates crosstalk issues prevalent in conventional standalone servos and improves overall system stability and reliability. It minimizes braking energy loss, delivering an average energy consumption reduction of approximately 30%. Lower braking heat generation reduces cabinet temperature rise, cuts failure rates of electrical components and extends overall system service life.

7. Dedicated Upper Computer Software Simplifies Sizing & Commissioning

The M900 is paired with exclusive upper computer sizing and debugging software supporting intelligent project sizing. After motor selection, the tool automatically matches compatible servos, cables, braking resistors and other parts, and generates complete order lists with one click. It also plots multi-axis motion curves to rapidly identify process defects and drastically shorten commissioning cycles.

8. Multi-Bus Compatibility for Full Coverage of High-End Industrial Scenarios

Supporting dual communication buses including PROFINET and EtherCAT, the M900 is widely applicable to high-standard, high-precision multi-axis transmission applications such as CNC machining, laser processing, glass manufacturing, 3C automation, robotics, printing & packaging, warehousing logistics, lithium batteries and photovoltaics.

The official launch of the M900 marks a phased achievement of Motong’s long-term R&D in modular multi-axis servo technology. From the first generation that realized groundbreaking core technology, the second generation optimized for universal system compatibility, to the third-generation M900 delivering architectural innovation, upgraded performance and full-scenario adaptability, Motong has built a mature, fully in-house developed multi-axis motion control technology ecosystem. It provides the industry with a practical, high-performance and cost-effective new technical path for multi-axis servo upgrades.

Riding the wave of intelligent manufacturing transformation, Motong will continue deepening research into core underlying motion control technologies, iterating product performance, optimizing modular architectures and expanding industry compatibility. Through continuous technological innovation, we will empower manufacturing industries to achieve higher efficiency, superior precision and lower carbon emissions, and further consolidate our leading position in modular multi-axis servo technology.
