Speak to our engineers about your project

Our experienced engineers are on hand, ready to help with your project. Whether you need the Elmo Motion Control Platinum Maestro itself, help sourcing it, or a modified or custom design built around your load, speed and space, tell us what the machine has to do and we'll come back with the right option.

  • Help sourcing Platinum Maestro and spares for installed machines
  • Modified and custom designs when a catalogue part doesn't fit
  • Complete axis: motor, drive, gearing and feedback matched together

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 Elmo Motion Control Platinum Maestro

Send these with your enquiry and an engineer can confirm the right Platinum Maestro 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

Elmo Motion Control Platinum Maestro: frequently asked questions

What is the Elmo Motion Control Platinum Maestro?

EtherCAT multi-axis motion controller mastering up to 256 axes with cycle times down to 250 us, programmed in IEC 61131-3 and C++. It is made by Bosch Rexroth AG (Bosch Group); Specify Motion can help source it or propose an equivalent.

Who makes the Elmo Motion Control Platinum Maestro?

The Elmo Motion Control Platinum Maestro is made by Elmo Motion Control (Bosch Rexroth AG (Bosch Group)) and is listed here for engineers comparing options. Specify Motion is not affiliated with Bosch Rexroth AG (Bosch Group); brand names are used only to identify the product.

Is there an alternative to the Elmo Motion Control Platinum Maestro?

Yes. Our engineers can propose an equivalent built around your load, speed and environment. An engineer confirms the fit against your application before recommending anything.

What is the difference between a motion controller and a PLC?

A PLC handles machine logic, sequencing and I/O. A motion controller specialises in trajectory planning and coordinating axes. Many modern controllers combine both, running PLC logic and motion libraries on one CPU. Choose based on axis count, motion complexity and timing requirements.

Why is EtherCAT common for motion control?

EtherCAT offers short cycle times, precise synchronisation using distributed clocks and simple cabling, which suit coordinated multi-axis motion. Many drives and I/O devices support it. Other real-time networks such as PROFINET IRT and Sercos are also used, so check what the drives and controller support.
