Synchronous Mode And Nc/Plc Interface Signals - Siemens SINUMERIK Series Function Manual

S3: Synchronous spindle
13.4 Points to note
Supplementary condition
IS DB31, ... DBX31.4 (resynchronization) has any effect only if there is a defined offset
position between the following spindle and leading spindle.
This is the case following

Synchronous mode and NC/PLC interface signals

Note
During synchronous operation, the effect of the associated interface signal for the leading
(LS) or following spindle (FS) on the coupling must always be considered.
Spindle override (DB31, ... DBB19)
Only the spindle compensation value of the LS acts in the synchronous operation.
Spindle disable (DB31, ... DBX1.3)
Controller enable (DB31, ... DBX2.1)
LS: Resetting the "controller enable" during synchronous operation
If the controller enable of the LS is reset during synchronous operation for active setpoint
coupling, a control-internal switching is made to the actual value coupling. If the controller
enable is reset while the LS is traversing, the LS is stopped and an alarm issued.
Synchronous operation remains active.
LS and FS: Selection of synchronous operation without controller enable
If the "controller enable" for LS and FS is not set for selected synchronous operation, it will
be activated. LS and FS, however, are not traversed until controller enable for LS and FS
has been granted.
