Function with Direct Synchronization
The drive accelerates the master speed at the ramps parameterized in the motion
block. At the start of a motion block the drive is sychronised with the master drive
directly. The master speed is processed by the position controller directly.
The acceleration and deceleration for synchronization occurs according to the charac-
teristic of an S-shaped curve.
The relative position shift between master and slave due to the acceleration
is compensated by the Position Controller.
