APPLICATION NOTE: Servo Loop Tuning – practical approach
Direct drive servo actuators have an unquestionable performance capability, the final performance is mostly determined by the servo loop tuning.
Servo motors have the...Controllers and Drives
Low Friction System – Effect of Derivative Term
In a low or no friction air bearing system, the response has a tendency to become unstable quickly, even with low gains.
To remedy this instability, derivative action is required. Because the D term differentiates the position error which changes fast in case of...Linear actuators moving carriage
System builders look for software that is both easy to use and powerful; a software that can handle both simple tasks quickly while having the “depth” to be used for more complex scenarios. Usually this becomes a tradeoff between “simple to use” and “very powerful” for which a solution is not easily...Linear actuators moving carriage
Our next task will be to show how variables can be used in place of “hard coded” values to facilitate external parameter change. Then conditional branching will be used to call subroutines via a variable change or I/O.
First variables need to to be assigned. There are two types within the “SmartMotor” control scheme:...Linear actuators moving carriage
To complete this illustrative programming exercise, we will add another typical layer of complexity, called Multithreading.
This will give us the capability to run 2 independent programs simultaneously. One of those programs will be what we have created so far. The second program will be new.
Its task will be...Rotary tables
The 350 mm diameter center opening in the RotoRing300™ rotary table easily accommodates large 300 mm (12″) semiconductor wafers, allowing for eased extraction of the chip dies from the wafer during semiconductor assembly manufacturing processes.
The RotoRing300™ direct drive rotary table from IntelLiDrives adapts...XY and XYZ systems
Repeatability and accuracy are important characteristics of any motion control system
and the objective of the system is to assure the desired trajectories can accurately followed through the mechanical range of the system.
In traditional XY gantry designs upper gantry member (Y axis) is carried by two identical bottom...Linear actuators moving carriage
Effectively automating any industrial operation, test procedure, or prototype process involving motion requires determining the movement precision needed to yield acceptable results.
A motion system ideally positions to a given target point with some small amount of tolerance or uncertainty. However, motion system performance...Controllers and Drives
Definition: The smallest achievable positioning increment that can be achieved by the motion control system.
Contributing factors: Drive screw pitch, gear drive ratio, motor/encoder combination perfromance
The threshold of minimum motion a positioning system can realize or sense defines its resolution.
Elasticity...Linear actuators moving carriage
Almost every task in the production/manufacturing such as, the machining, the packaging, the handling, the storing, the sorting and the retrieving etc. and also, the majority of other non-production related tasks in our daily life are characterized by the controlled motion of work pieces, tools, or generally characterized by...
