The release of the maxon EPOS4 Micro 24/5 CAN positioning controller has realized the option of significantly minimizing the “real estate” traditionally occupied by motor controllers.

The Micro is capable of motion control of brushed DC motors with encoders, and brushless DC motors with hall sensors and encoders. With a 5 A continuous current output, this miniature controller allows precise control of motors up to 120 W continuously (360 W intermittently).

Given its miniature size, measuring 32 x 22 x 7 mm, it was not designed to offer connectors for a plug-and-play facility (unlike the “EPOS4 Compact”). Integration of the Micro into a drive system requires integration through motherboard electronics design, which can be costly and time-consuming. if an application-specific PCB is not already being developed.

To eliminate this cost, and to give designers an easy development path, the maxon Australia engineering team developed the EPOS4 Micro 24/5 CAN 3-Axes Motherboard as an easy-to-integrate solution to multiaxis motion control. In this case, a single 3-Axes Motherboard offers the ability to control up to 3 x DC/BLDC motors. Achieving multiaxis motion control has never been more accessible.

As the EPOS4 Micro controllers are CANopen slaves, they require a CANopen master to send data and commands. With the 3-Axes Motherboard, connection to a CANopen master and the rest of the CAN bus is made easy with two CAN connectors. Adhering to the CiA 402 protocol, the EPOS4 Micro controllers are standardized Motion Control Slaves, ensuring compatibility with motion libraries from various PLC manufacturers.

Recognizing the often-intricate nature of drive elements within complex systems, the 3-Axes Motherboard provides extensive connectivity options. The motherboard caters to 4 x digital inputs, 2 x analog inputs, and 1 x analogue output for each EPOS4 Micro. With the flexibility to connect an SSI absolute encoder for each axis, the available options will have you covered for most applications. Each axis can be configured individually over a USB connection. The EPOS Studio software offers regulation tuning, parameter configuration, and object dictionary visualization tools to assist in the integration process.

The 3-Axes Motherboard has been optimized for size, measuring 84 x 54 x 27.3 mm, without a trade-off in functionality. This small size means the motherboard is still viable if you are only driving one or two motors, and the units can be daisy-chained for any multiple DC motors required for the application.

For those seeking tailored solutions, the maxon Australia engineering team stands ready to offer a spectrum of services, including motherboard design and custom modifications, software programming and configuration, and comprehensive system design.
