HSC filter
Step response
Contour deviation adjustment aid
The contour deviation when using HSC axis filters is composed of three components.
1. Cycle time
2. Filter order
3. Feed rate
The following simple relationships apply:
1. Double cycle time = double error
2. Double feed rate = double error
3. Double filter order = double error
The following graphic was drawn up for a cycle time of 1ms and F1000 feed rate on a 90 degrees corner. For other edge data, the filter orders must be converted in accordance with the above relationships.
