Note
● All other values refer to axis mode
● If the spindle is a following spindle or several couplings, then the value of the coupling state of all
● Current angular offset
The current angular offset of the following spindle to the leading spindle can be read via:
– $AA_COUP_OFFS[<FS>] (angular offset on the setpoint side)
– $VA_COUP_OFFS[<FS>] (angular offset on the actual value side)
Application example
Correction of the angular offset difference in the NC program after cancelling the follow-up
mode:
Angular offset difference = programmed angular offset - system variable

Generic coupling (CP...)

"Generic Coupling" is a general coupling function, combining all coupling characteristics of
existing coupling types (coupled motion, master value coupling, electronic gearbox and
synchronous spindle).
The function allows flexible programming:
● Users can select the coupling properties required for their applications (building block
principle).
● Each coupling property can be programmed individually.
● The coupling properties of a defined coupling (e.g. coupling factor) can be changed.
● Later use of additional coupling properties is possible.
● The coordinate reference system of the following axis (base coordinate system or machine
coordinate system) is programmable.
● Certain coupling properties can also be programmed with synchronized actions.
