Dynamic Adjustment

Purpose
The dynamic adjustment is used to compensate delays resulting from the
connected switching elements.
Lead Time
This delay can be specified as a lead time that you specify separately for each
cam. Per cam, you can specify one lead time. The lead time applies to the cam
start and cam end.
Lead Distance
The lead distance of a cam is calculated continuously depending on the current
feedrate and the lead time. The entire cam is displaced by this distance in the
direction of the actual value. The range selected is known as the "static range", the
range calculated as a result of the lead time is known as the "dynamic range".
Lead distance
Calculation of the lead distances of all cams is carried out within
If you set a very large lead time for a cam, you reduce the dynamics of the cam
processing.
