ETEL: Motion Control (AccurET Series)
The AccurET and UltimET motion control solutions benefit from ETEL’s long experience in linear/torque motors, motion systems and motion controllers. This range defines the new standard for motion control in the industry: UltimET Light motion controllers and AccurET position controllers offer unmatched performance in such a small volume. Now, the customer can improve machine’s throughput and save space at the same time!
The full ETEL solution allows machine builders to simplify mechanical integration in their machine thanks to a very consistent design and a modular architecture that is easy to wire and mount. It also gives customers the opportunity to focus on their core competence and technology while ETEL takes care of motion systems development.
ETEL’s motion control solutions have been integrated into leading edge machines of various high-tech industries for more than 15 years. ETEL’s range of motion controllers (UltimET) and position controllers (AccurET) allows machine builder to drive any available servo motors on the market (brushless, DC motors, steppers) with the highest performance regulation in a minimal footprint.
Its decentralized architecture ensures the same level of performances and speed regardless the number of axes to drive in the machine. Distributed architecture also makes cabling easier to manage and to maintain in the field. Last but not least, the software environment, ComET and EDI, simplifies software development, machine installation and maintenance.
Why should you use ETEL’s controllers?
Highest performance in direct drive control
- Deterministic synchronization or interpolation for high-end multi-axis applications
- Advanced servo algorithms
Very high speed communication through ETEL real-time bus (TransnET)
Compact form factor and simple cabling for an easy machine building
ComET user-friendly software tools for setup, monitoring and system identification have been designed to help customer to improve system’s runtime capabilities
AccurET: A modular position controllers family of high performance.
AccurET position controllers cover a wide range of voltage and current levels in a compact solution. This makes the integration of various servo motors in a single machine very easy.
Their modular mounting design makes AccurET position controllers a very compact solution:
Each controller can drive two axes and a single power supply can be used for multiple AccurETs sharing the same DC bus voltage.
An optional board can be embedded into an AccurET, such as the UltimET motion controller or the I/O board.
No rack is needed, making the required volume only dependent on the number of driven axes.
Simplified power and communication cabling as well as modular cooling unit make the machine installation and maintenance easy to perform.
Machine builders will appreciate this design: cost effective, compact, quickly integrated, and easy to replace in the field.
Increase the throughput of your machine thanks to AccurET
AccurET current loop is highly reliable: Parasitic movements can be avoided thanks to its very low noise. In addition, its high bandwidth allows to: Maximize the bandwidth of the position loop. Benefit from advanced feed forward, and better compensate for friction, viscosity, as well as repeatable perturbations such as cogging, etc.
ETEL’s advanced regulator provides all you need to get the maximum performance out of your mechanical design.
Altogether, AccurET minimizes errors during axes movement and therefore dramatically reduce the settling time.
Increase your machine accuracy with AccurET
3D mapping is available standard so you can compensate repeatable defaults such as mechanical distortions.
ETEL position controllers can handle a variety of external signals. For example, fast position capture or fast trigger allows the management of other devices such as laser, camera, etc. They can either be based on the real or on the theoretical position of the axis, or time based depending on application’s requirement.
AccurET is also very well suited for high speed applications requiring high accuracy at the same time: the trajectory filter function is an enhanced vibration suppression function used to reduce machines’ vibrations and settling time. It is designed to avoid transmitting chassis vibrations on the load.
In addition, customized motion sequences can be run on each controller thanks to the ETEL structured programming language. The user defined “macro” functions allow machine builders to customize their position controller to their machine process. For more performance, each controller can run up to two motion sequences in parallel, independently of the other axes. As an example, one motion sequence can process all distance information to maintain a constant gap to the processed surface. While another sequence running in parallel handles errors for the same motor.
AccurET position controllers contain integrated protection and diagnostics for machine and, more importantly, stage protection: over-temperature detection, over-current and voltage, loss of feedback, etc. ETEL provides all necessary features to build a reliable machine.
ETEL controllers support standard encoders of the market, such as analog 1 Vpp, Absolute EnDat 2.1 and 2.2, as well as TTL. Absolute position feedback enables one to perform the machine initialization phase without any axis movement. This saves startup time and avoids any collision risk during this phase.
AccurET supports different communication types.
ETEL TransnET for multi-axis real-time applications. TransnET’s synchronization jitter in the nanosecond level is the right answer for deterministic and reliable communication within machines.
TCP/IP allows commissioning and machine management during operations. This can be used in cases where controllers are used in stand-alone configuration.
USB can be used for commissioning and maintenance at any time.
Input and Output Interfaces
Each AccurET controller has embedded inputs and outputs to interface or trigger external devices. In case you need a higher number of motion control related I/Os, ETEL also proposes:
The optional I/O board fitting into an AccurET optional board slot is adding 4 analog Inputs and 4 analog Outputs, as well as 8 digital Inputs and 8 digital Outputs.
A WAGO gateway module can be connected to the UltimET board allowing communication through Modbus TCP, interfacing up to 16 analog Inputs and 16 analog Outputs as well as 128 digital Inputs and 128 digital Outputs.
