18.13 Synchronous Spindles (S3)
18.13.1 Signals to axis/spindle (DB31, ...)
DB31, ...
DBX31.5
Disable synchronization
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
The synchronization motion for the following spindle is not disabled from the PLC.
The position offset is not suppressed and applied as in earlier versions.
Signal state 0 or edge
change 1 → 0
The synchronization motion for the following spindle is disabled from the PLC.
A synchronization motion specified via offset programming is suppressed for the following
spindle. The following spindle does not execute any additional movement.

18.13.2 Signals from axis/spindle (DB31, ...)
DB31, ...
DBX84.4
Synchronous mode
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
The spindle is operating in "Synchronous operation" mode. The following spindle thus follows
the movements of the leading spindle in accordance with the transmission ratio.
The monitoring functions for coarse and fine synchronism are implemented in synchronous
operation.
Note:
The signal is set only for the machine axis which is acting as following spindle
(IS "FS active" = 1)
Signal state 0 or edge
change 1 → 0
The spindle is not operated as the following spindle in "synchronous mode".
When the coupling is deactivated (deselection of synchronous operation), the following
spindle is switched to "open-loop control mode".

DB31, ... DBX99.1 (FS active)
