Controlling Piezo motors
Piezo motors are becoming more and more used in today's precision motion stages. Motion controllers used to control piezo devices must have that ability to modify the servo loop, to add a controllable offset and dead band around the zero crossover point. This compensates for the non linearity in the piezo amplifier. If you are considering using piezo motors, our technical note discusses how to setup Trio Motion Coordinators.

'Networked drives'; the way forward
Trio firmly believes that networked drives provide many future advantages to users of servo motors. The main advantage to users will be the cost reduction achievable on multi axis systems. Important time is saved in connecting digital drives to the controller using commercially available pre-made
cables, whilst also reducing the number of wires needing
termination. The new MC464 features 'plug &
play' installation, allowing easy setup of your digital drives through the Motion Coordinator. With support for up to 64 axes, reliable digital communications and diagnostic information from the whole system; why not check out the future of motion control.

Increased registration accuracy at high speed The registration (position capture) circuit of the Motion
Coordinator latches current encoder position very precisely. Better than 1 microsecond response is
available in the capture circuit itself.
In most real-world systems however there are other fixed delays built into the
registration circuit such as the sensor and the input opto-isolator response times. As machine
speed increases, these fixed delays will affect the accuracy of the
captured registration position. Trio have now added new functionality to increase accuracy.

Custom kinematic transformations  Ever wanted to program complex mechanical systems in the easy to use cartesian coordinate system? As an example a Scara robot is often complex to program due to having to convert XY coordinates into polar coordinates. Using Motion Coordinators you simply configure a standard transformation and program the robot in cartesian coordinate system.
What happens if you have a non standard mechanical setup? Learn how to setup complex custom transformations as well as the library of standard transformations that are already available. |
