General boundary conditions
The following boundary condition must be observed:
• A slave axis can only be assigned to one master axis
• One master axis can be assigned several slave axes
• A slave axis must not be a master axis or be in another master-slave relationship.
NOTICE
Drive optimization
At a SINAMICS S120 drive unit, a maximum of 3 drives can be optimized or measured at
the same time (speed controller optimization/function generator). Therefore, for a
coupling with more than 3 coupled drives at the same time, we recommend that these are
distributed over several drive units.
