Moog DM2020 Multi axis Servo Drive: Compact, Efficient, and Highly Dynamic Motion Control Core

Product Overview and Core Values

Moog Industrial, as a global leader in motion control, has always been committed to providing excellent technical solutions for industrial automation, robotics technology, medical equipment, and high-precision mechanical systems. The DM2020 series multi axis servo drive is its latest compact digital drive platform, focusing on improving the dynamic performance, synchronization accuracy, and energy efficiency of multi axis systems. This product not only inherits Moog's decades long technical accumulation in the field of servo control, but also provides users with a highly flexible and easy to configure system construction solution through modular and integrated design.

The DM2020 driver adopts the "functional block" design concept, separating the power module from the shaft module, and achieving energy flow and recovery between shafts through a shared DC bus architecture, significantly reducing system energy consumption and heat dissipation requirements. Its compact mechanical structure saves about 50% of installation space compared to traditional standalone drivers, significantly reducing wiring complexity and the number of peripheral components, making it particularly suitable for applications with limited space and high requirements for system integration.

Modular design and system architecture

The DM2020 series adopts a highly modular hardware platform, which is divided into two categories: Axis Module and Power Supply Module. The shaft module is divided into multiple width specifications (50mm, 75mm, 100mm, 200mm) based on its output current capability, while maintaining a consistent height and depth (455mm × 249mm) for easy cabinet layout and heat dissipation management. The power module offers two sizes of 50mm and 150mm, supporting three-phase 65-528V AC wide voltage input and providing stable DC bus voltage and 24V auxiliary power supply for the system.

The core advantage of its multi axis architecture lies in its dual axis integrated design: a single physical module can accommodate two independent servo axes, sharing heat dissipation, power supply, and communication interfaces. Each module only requires one EtherCAT or CANopen node, significantly reducing the number of fieldbus nodes and improving system real-time performance and network management efficiency. Inter axis synchronization can be achieved in milliseconds through an internal bus, supporting advanced motion modes such as primary/secondary, gantry synchronization, electronic gears, etc., to meet the requirements of high-precision collaborative operations.

High performance control and feedback system

DM2020 is equipped with a real-time high-performance EtherCAT bus as the main control interface, compatible with CANopen and analog/simulation encoder interfaces, and supports CIA 402 driver specifications. Its control card adopts high-speed digital signal processor and high-precision analog-to-digital converter, with excellent dynamic response and anti-interference ability. Users can customize control algorithms through advanced tools such as Simulink and MatLab to achieve more accurate motor control and position adjustment.

In terms of feedback system, the driver supports multiple motor types (brushless, asynchronous) and sensor interfaces:

Resolver: equipped with attenuation correction, cable phase compensation, and gain adjustment functions, suitable for harsh working conditions.

Encoder interface: software configurable to support multiple protocols, including:

Heidenhain EnDat 2.2 (single lap/multi lap absolute value)

Stegmann Hiperface (single lap/multi lap absolute value)

SinCos encoder (powered by 5-8V)

Each axis module comes standard with an encoder interface and a rotary converter interface, and can be optionally equipped with a second encoder channel to achieve dual feedback redundancy or additional position detection, improving system reliability.

Energy saving technology and thermal management

DM2020 achieves energy feedback through shared DC bus: the regenerated electrical energy generated during motor deceleration or braking can be supplied to other shafts in acceleration state, thereby reducing the energy dissipation of braking resistors and reducing the overall energy consumption of the system by 10-30%. In addition, the optional auxiliary capacitor module (ABC Module) can further enhance the braking energy storage capacity, achieving up to 3kW of energy-saving effect in high-speed cycling applications (such as 200 cycles per minute).

The entire series of modules adopts a built-in forced air cooling design, with high heat dissipation efficiency, allowing full power operation at ambient temperatures of 0-40 ° C, and can support up to 55 ° C (with a 2%/° C derating required). The protection level is IP20, suitable for installation inside industrial cabinets. All modules have safety functions such as overheating protection, phase loss detection, and undervoltage/overvoltage protection.
