AccurET: A modular position controller family for higher performance and easy integration
AccurET Position Controllers cover a wide range of voltage and current levels in a homogeneous and compact solution. This makes the integration of various servo motors in a single machine easier than ever.
A MODULAR DESIGN
Compact size:
 AccurET has been designed to fit in the smallest space available on machines
Each controller can drive two axes to provide a cost effective solution
Slot available for optional board: UltimET light, I/O board, …
Scalable form factor depending on the number of axis needed:
One single power supply can drive several AccurET using the same input voltage
Different voltage level can be combined within the same application
Easy to integrate:
Easy cabling for power and communication
Easy mounting process
Modular cooling unit
INCREASE THE THROUGHPUT OF YOUR MACHINE THANKS TO ACCURET:
AccurET current loop is highly reliable: Parasitic movements can be avoided thanks to its 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.
All together, AccurET minimizes errors during axes movement and therefore dramatically reduce the settling time.
INCREASE YOUR MACHINE ACCURACY WITH ACCURET:
Mapping up to 3D is available in standard so you can compensate repeatable defaults such as mechanical distortions.
ETEL Position Controllers can handle different external signals. Fast position capture or fast trigger, for example, 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.
AccurET Position Controllers contain built-in protections and diagnostics for machine and, more importantly, for stage protection: over-temperature detection, overcurrent and voltage, loss of feedback, etc. ETEL provides all needed features to build a reliable machine.
ETEL Controllers support market standard encoders, such as analog 1Vpp, Absolute EnDat 2.1 and 2.2, as well as TTL. Absolute position feedback enables to perform 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 to deterministic and reliable communication within machines.
Ethernet TCP/IP allows commissioning and machine management during operations.
USB can be used for commissioning and maintenance at any time.
