Example of electronic gear
Axis 4 is coupled to axis X via an electronic gear coupling. The acceleration capability of the
following axis is limited to 70% of maximum acceleration. The maximum permissible velocity
is limited to 50% of maximum velocity. After successful activation of the coupling, the
maximum permissible velocity is set to 100% again.

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