ETEL: Motion Control (UltimET 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
UltimET light: Powerful Multi-Axis Motion Controllers
UltimET Light motion controller is the master on the TransnET bus and can manage up to 63 axes. More significantly, the communication performance will be the same regardless of the number of axes.
To provide the best price/performance solution to its customers, ETEL designed two versions of the motion controller: the UltimET Light smart gateway is designed for price sensitive applications requiring synchronized movements. The UltimET Light interpolation version is best suited for interpolated movements.
UltimET Light provides different ways to manage multi-axis movements, depending on the needs:
Movements can be either synchronized, or interpolated with G-code based, ULM (Universal Linear Movements), PVT (Position Velocity Time), PT (Position Time) and LKT (LooK-up Table) motion profiles.
Advanced control feature requiring slave to slave communication between the different position controllers need an UltimET as a TransnET master: - 3D mapping allows for correction of a stage’s known mechanical errors - Gantry acceleration feed-forward - Etc.
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.
UltimETs are available in three form factors in order to adapt to OEMs configuration:
The PCI or PCI Express version are integrated into a PC, which is very well suited for high speed applications requiring real-time deterministic communication.
The TCP/IP version is embedded into an AccurET position controller. This configuration is best for stand-alone machines, in which the motion control application is far from the PC controlling the machine.
TransnET: Real-time 1Gbit Communication Bus
TransnET is a gigabit ethernet based fieldbus designed to be the communication channel in ETEL‘s distributed motion control architecture. TransnET manages the real-time commands between the UltimET Light motion controller and AccurET position controllers driving up to 63 motors at the same time. It allows for handling of highly reliable deterministic synchronization and interpolation. In addition, TransnET nanosecond synchronization jitter allows for master to slave, slave to master, or slave to slave communication withinthe same cycle. This is a major advantage for high-end machines, since most require extensive slave to slave communication to perform 3D mapping, gantry control, and more.
