Notes on this data

Axis count and cycle time not published on the page.

Specify Motion is not affiliated with Baumüller Nürnberg GmbH (family-run Baumüller Group). Baumüller and b maXX PLC mc are used only to identify the product. Comparisons use published figures; always confirm against the current datasheet.

Typical applications

Alternatives that meet or exceed these figures

Engineers often come to us with a Baumüller part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 2 series from our supply network are the closest match on published figures.

Motion controller

Kinco AK (AK8 / AK840)

Slim 54 mm EtherCAT motion controller programmed in CODESYS, running up to 32 synchronised axes on a 1 ms cycle with RP20 I/O expansion.

Motion controller

Leadshine MC500 (MC508CS / MC516CS / MC532CS)

CODESYS-based PLC/motion controller with EtherCAT for 8, 16 or 32 axes plus 6 local pulse axes, dual-core SOC+FPGA and 32-module R2 I/O expansion.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.

What a motion controller is

A motion controller plans and coordinates movement for one or more axes, sending position, velocity or torque commands to servo or stepper drives. It generates trajectories with defined acceleration and jerk, synchronises axes for interpolation, electronic gearing and camming, and handles homing, limits and registration inputs. Commands reach drives over pulse, analogue or, most commonly now, EtherCAT and other real-time networks. Many controllers also include PLC functions to IEC 61131-3, combining logic and motion.

When engineers choose a motion controller

Choose a dedicated motion controller when a machine needs coordinated multi-axis motion beyond basic point-to-point moves, such as robots, gantries, packaging and CNC. It gives deterministic timing and motion libraries. The trade-offs are cost, programming effort and ecosystem lock-in. For simple machines with a few independent axes, a PLC with motion function blocks or intelligent drives with stored moves may be enough.

How to specify the Baumüller b maXX PLC mc

Send these with your enquiry and an engineer can confirm the right b maXX PLC mc variant or an equivalent:

• Number of axes and drives
• Network and cycle time (ms)
• Motion functions: interpolation, camming, robotics
• Programming environment and languages
• I/O and expansion
• HMI and connectivity
• Safety integration

Common mistakes to avoid

• Choosing a controller that does not support the drives' network
• Underestimating cycle time needs for many axes
• Ignoring programming tools and skills in the team
• Not planning for future axis count
