A.1.6
DynamicLimits tags (speed axis)
The tag structure <TO>.DynamicLimits.<tag name> contains the configuration of the
dynamic limits. During Motion Control, no dynamic values greater than the dynamic limits are
permitted. If you have specified greater values in a Motion Control instruction, then motion is
performed using the dynamic limits, and a warning is indicated (alarm 501 to 503 - Dynamic
values were limited).

A.1.7
DynamicDefaults tags (speed 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.
