Approach response for moving FA
The following axis moves at almost maximum velocity in the positive direction when the
coupling is activated by EGONSYNE. The programmed synchronized position of the
following axis is 110, the current position 150. This produces the two alternative
synchronized positions 110 and 182 (see table above).
In the case of traversing mode NTGP (path-optimized), synchronized position 182 is
selected independent of the current velocity. This has the shortest distance from the current
position of the following axis. Traversing mode NTGT (time-optimized) considers the current
speed of the following axis and produces a deceleration on account of the limit for the
maximum axis speed to reach synchronism in the shortest possible time (see Figure).
