Curve, RU curve Acceleration, Deceleration | Hitachi J300U Series

Appendix 4 Acceleration/Deceleration Curve Constants

This function can vary the curvature when the acceleration curve pattern (or deceleration curve pat- tern) is selected to S curve, U curve or RU (reverse U) curve in the function mode (F-06). If the acceleration curve pattern or deceleration curve pattern is selected, the selected pattern applies to both acceleration and deceleration.

The larger number causes a greater curvature.
