Function with Direct Synchronisation
The drive accelerates the master speed at the ramps parameterized in the motion
block. At the start of a motion block the drive is synchronised 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 change caused by the acceleration is not compensated.
