20 Quick reference guide
Use this appendix in conjunction with as a reference guide when programming the Power Focus. A more
general description of the tightening and control strategies available can be found in the previous chapters.
A joint is regarded as hard if α (clamping angle) is small, and soft if α is
large. There is no limit, but test standards define α < 30 as hard. The
dynamic effects on tightening increase dramatically if angles go down
substantially (approximately 15ï‚°).
On the following pages, different control and monitoring strategies are calculated. Study the graphs and
the parameters that need to be set. Note that the graphs are presented schematically, which means that
programming results may look different compared to the graph.
