Example 2: Electronic gear
Axis 4 is coupled to axis X via an "electronic gear" coupling. The acceleration capacity of the
following axis is limited to 70% of the maximum acceleration. The maximum permissible
velocity is limited to 50% of the maximum velocity. Once the coupling has been activated
successfully, the maximum permissible velocity is restored to 100%.

Example 3: Influencing master value coupling by static synchronized action
Axis 4 is coupled to X by master value coupling. The acceleration response is limited to
position 80% by static synchronized action 2 from position 100.
