Motion Control Linear Stage

Demanding series production for a medical instrument

The task was to develop a motion unit for a computer tomography scanner which moves tungsten collimators during X-ray source rotation so that the X-ray beam can be adjusted to the minimum radiation dose required. The assembly itself is continuously moved in a circular path around the patient during use. A special challenge was the high acceleration caused by the rotation on a large diameter transverse to the direction of movement. This additional load requires a particularly stable construction with minimal potential for error.

Highest stability and reliability

Since this is used in a durable medical device, the requirements for functional safety and reliability are very high. The positioning system has been tested for three million application cycles and has proven this claim with statistical certainty in an endurance test.

Motion Control – EPOS4 Position Controller, Compact Power for Your Motion Control Application!

Maxon motor’s EPOS range of controllers has been very successful in the marketplace. Since its launch in 2005, more than 100,000 units are in use worldwide. To build upon this success, the Swiss drive specialist launches the EPOS4 as the next generation of positioning controllers.

Fall River, MA — The first product in maxon’s new line is the high-performance EPOS4 module with detachable pin headers and two different power ratings. With a connector board, the modules can be combined into a ready-to-install compact solution. The position controllers are suitable for efficient and dynamic control of brushed DC motors and brushless BLDC motors (EC motors) with Hall sensors and encoders up to 750 W continuous power and 1500 W peak power.

More performance and additional functionality

The Swiss drive specialists at maxon motor has equipped its product offering of CANopen positioning motor controllers with even more power, better control performance, and additional functionalities. The modular concept also provides for a wide variety of expansion options with Ethernet-based interfaces, such as EtherCAT or absolute rotary encoders. All these innovations are based on the successful principle of our Easy to use POsitioning System.

The combination of a wide variety of operating modes and state-of-the-art control characteristics like Field Oriented Control (FOC) with multiple analog and digital I/O along with various command options enables applications in a large number of fields from medical technology to robotics. As always, maxon relies on integrated protective devices like the Safe Torque Off (STO) functionality.

Intuitive parameterization!

Start-up and parameterization are performed with an advanced, intuitive graphical user interface called “EPOS Studio” and user-friendly menu-controlled wizards. A sophisticated automatic process for controller tuning has also been part of the package for years. Customers are free to fully dedicate themselves to their real task – developing their devices. Motor control becomes a secondary concern, as the EPOS comes with maxon’s comprehensive know-how in drive technology. Together with the three freely available libraries and programming examples, this makes the integration in a wide variety of systems very easy.

Up to 98% efficiency

All these characteristics are combined with a large input voltage range of up to 50 VDC, extremely high power density, and up to 98% efficiency. This makes EPOS4 position controllers the first choice for your drive application.

Motion Control – Maxon’s High-Performance MAXPOS 50/5 Controller!

Motion Control- Maxon motor launches the MAXPOS 50/5. This compact EtherCAT Slave unveils unprecedented possibilities as far as precision, dynamics, and synchronization are concerned. It also ensures reliability and durability even under harsh conditions. More than 20 years of experience in motion control have been incorporated into this latest technology in positioning controller.

Maxon Logo

Fall River, MA — Motion Control Controller – By their design, the ironless maxon DC brushed motors and brushless (maxon EC) motors are ideal for applications demanding high dynamics and longevity. Typical areas are robotics and applications in the medical industry or in specialized machine manufacturing. In the past when particularly high requirements were called for, the controller used or its limited integration capabilities to the master occasionally imposed limitations due to its inability to keep pace with the high dynamics of the motors. With the new MAXPOS 50/5 motion controller, these core motor properties can now be ideally utilized. Thanks to the latest FPGA (Field Programmable Gate Array) technology, highest control cycle rates can be achieved with minimally short cycle times at the same time. For trajectory planning, sophisticated motion control tasks with a current controller clock speed of 100 kHz and an effective communication cycle time of 100 μs can be achieved with a suitable EtherCAT master. Distributed Clocks Support as well as the endorsement of CoE (CAN Application Layer over EtherCAT) with «Cyclic Synchronous Modes» perfectly suit these purposes. As an alternative, profile-based operating modes for position and velocity are also available. In addition, the outstanding processing power provides field-oriented sinus commutation of brushless motors (maxon EC) up to a speed of 200,000 rpm.

Full connectivity

A multitude of feedback possibilities permit the use of a wide range of permanent magnet-activated DC motors with encoder and brushless motors (maxon EC) with digital Hall sensors and encoders up to 250 Watts. The wide supply voltage range from 10 to 50 VDC and the output power capability of 5 A continuous and 15 A peak current opens a broad application field. Two different encoders can be used simultaneously allowing for dual loop control of the master to compensate for mechanical backlash and elasticity of the drive system. This is ideal for applications with high demand on precision. The spectrum ranges from digital incremental encoders to analog sinus-cosinus incremental encoders up to absolute encoders with SSI, EnDat2.2, or BiSS-C interface. Of course, also galvanically isolated I/Os are on board to enable integration of diverse peripheral components, such as limit or reference switches.

All-around protection and easy operation

The MAXPOS 50/5 positioning controller also comes with extensive protective circuitry against overcurrent, excess temperature, undervoltage and overvoltage, voltage transients, short-circuits in the motor cable as well as loss of feedback signal. Motor and load can be optimally protected with adjustable current limiting.

The newly designed operating concept for the graphical user interface «MAXPOS Studio» together with well-established tools, such as Startup Wizard or automated Regulation Tuning ensures easy and intuitive commissioning. Additional aids include the Diagnostic Wizard for troubleshooting or a freely-configurable data recorder to plot various process data. Plus, to assist the customer in attaining the ideal matched drive system in the shortest possible time, a comprehensive document is provided. The entire configuration can be carried out via USB or Ethernet.
