Actual value coupling

FS "servo enable", the coupling relationship between the FS and LS is reversed and switched

Overlaid motion
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
The following spindle traverses an additional motional component which is overlaid on the
motion from the coupling with the leading spindle.
Examples of overlaid movement of FS:
- Activation of synchronous operation with defined angular offset between FS and LS
- Activation of synchronous operation with LS in rotation
- Alteration of transmission ratio when synchronous operation is selected
- Input of a new defined angular offset when synchronous operation is selected
- Traversal of FS with plus or minus traversing keys or handwheel in JOG when synchronous
operation is selected
As soon as the FS executes an overlaid movement, IS "Fine synchronism" or IS "Coarse
synchronism" (depending on threshold value) may be canceled immediately.
Note:
The signal is relevant only for the following spindle in synchronous operation.
Signal state 0 or edge
change 1 → 0
The following spindle does not traverse any additional motional component or this motion has
been terminated.

LS (leading spindle) active
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
The machine axis is currently active as the leading spindle.
Note:
The signal is relevant only in synchronous operation.
Signal state 0 or edge
change 1 → 0
The machine axis is not currently active as the leading spindle.
Special cases, errors, ... In the case of faults/disturbances on the following spindle which result in cancellation of the
FS "servo enable", the coupling relationship between the FS and LS is reversed and switched
over to an actual-value coupling internally in the control under certain circumstances.
In this case, the leading spindle becomes the new, active following spindle (IS "FS active").
