The Kollmorgen 2G Motion System pairs AKM2G servo motors with AKD2G servo drives to create a coordinated motion platform for precision automation. Instead of treating the motor and drive as separate components, the system is designed around their combined torque, feedback, communication, safety, and cabling requirements.

This approach can help machine builders increase axis performance without automatically increasing motor size, cabinet space, or wiring complexity. It also gives maintenance teams a clearly defined motor-and-drive architecture when repairing or replacing an existing axis.

The 2G Motion System Overview

The 2G Motion System consists primarily of two product families. AKM2G Magnetic Motors generate the mechanical torque required to move the load, while AKD2G Servo Drives regulate current, torque, speed, and position.

AKM2G motors are available in multiple frame sizes, winding configurations, feedback types, shafts, connectors, and brake options. AKD2G drives are offered in single-axis and dual-axis versions across 120/240 VAC and 240/480 VAC power classes. When correctly matched, the motor and drive operate as one closed-loop motion axis.

Why the Motor-and-Drive Pairing Matters

A servo system can only use the motor’s available performance when the drive can supply the necessary current and process the feedback signal correctly. Under sizing the drive can restrict acceleration or peak torque, while an incompatible feedback interface can prevent the axis from commissioning at all.

The AKD2G platform supports SFD, HIPERFACE DSL, EnDat, BiSS, resolver, incremental encoder, and other feedback options depending on the configuration. It also supports common industrial communication networks, including EtherCAT, CANopen, PROFINET IRT, and EtherNet/IP. (To learn more about these industrial communication networks check out our Industrial Automation Explained blogs) This allows the 2G platform to fit different control architectures without limiting every machine to one network or feedback format. 

More Motion Performance Without More Machine

AKM2G motors use increased torque and power density to provide greater output from a compact motor frame. This can allow an OEM to increase axis performance while retaining an established mounting envelope, although the required motor should always be selected from the actual torque, speed, inertia, and duty-cycle requirements.

The series includes standard AC windings and low-voltage configurations for 24 to 96 VDC systems. Available options include smooth or keyed shafts, holding brakes, thermal sensors, shaft seals, and several feedback devices. Standard construction is IP54, with IP65 configurations available when appropriately equipped. 

A Smaller and Cleaner Control Cabinet

AKD2G dual-axis drives allow two motors to be controlled from one drive package. This increases power density inside the control cabinet and can reduce the number of separate drive housings required for a multi-axis machine.

Single hybrid Kollmorgen servo cables can combine motor power, brake, and digital feedback connections when the selected motor and feedback system support that architecture. Fewer cable runs can simplify routing between the cabinet and machine while reducing the number of connectors that must be installed and inspected. Traditional two-cable motor and feedback configurations remain available for systems that require them. 

Integrated Safety and Diagnostics

AKD2G configurations support dual-channel Safe Torque Off, while selected versions provide expanded SafeMotion functions. These features allow the drive to participate in a properly engineered machine-safety system without requiring every safety action to remove power from the entire drive system.

A graphical drive display provides local operating, commissioning, and fault information. Removable memory and parameter backup features can also simplify configuration recovery, but the replacement drive must still match the original axis requirements, installed firmware, feedback device, network, safety configuration, and current rating.

A 2G Replacement Is More Than a Matching Frame Size

A motor with the same flange dimensions is not automatically a direct replacement. Winding, voltage class, torque-speed curve, shaft configuration, holding brake, feedback device, connector arrangement, and protection rating must also match the machine.

Drive replacement requires the same level of attention. Verify the number of axes, voltage class, continuous and peak current, communication protocol, feedback interfaces, safety functions, I/O configuration, firmware, and stored parameters. Matching the full type code provides a safer starting point than selecting equipment from the series name alone.

A failed servo motor or drive can stop an entire production cell, especially when the machine depends on a specific feedback, network, or safety configuration.
