Parameters
VELOLIMA[Ax], Change to limit for maximum velocity for following axis
ACCLIMA[Ax], Change to limit for maximum acceleration for following axis
JERKLIMA[Ax], Change to limit for maximum jerk for following axis

synchronized spindles.
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.
N120 ACCLIMA[AX4]=70 ;Reduced maximum acceleration

N200 VELOLIMA[AX4]=100 ;Full maximum velocity
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.
