DynamicDefaults tags (positioning axis/synchronous axis)
The tag structure <TO>.DynamicDefaults.<tag name> contains the configuration of the
dynamic defaults. These settings will be used, if you specify a dynamic value less than 0.0 in
a Motion Control instruction (exceptions: MC_MoveJog.Velocity, MC_MoveVelocity.Velocity).
Changes to the dynamic defaults will be applied with the next rising edge at the "Execute"
parameter of a Motion Control instruction.
