Deselecting The Synchronous Mode For The Part Program - Siemens SINUMERIK Series Function Manual

S3: Synchronous spindle
13.1 Brief description
Read current angular offset
Using axial system variables, it is possible to read the current position offset between the FS
and LS in the NC part program. A distinction is made between:
● Current position offset of setpoint between FS and LS
● Current position offset of actual value between FS and LS
(Explanation of <axis name>, see Section "Synchronous mode (Page 705)")
Activation after power ON
Synchronous mode can also be activated with non-referenced/synchronized FS or LS (IS
"Referenced/synchronized 1 or 2" DB31, ... DBX60.4 or DBX60.5 = 0). In this case, a
warning message is displayed.
Example:
LS and FS are already coupled in a friction lock via a workpiece after power ON.

Deselecting the synchronous mode for the part program

Open coupling (COUPOF, COUPOFS)
Synchronous mode between the specified spindles is canceled by the parts program
instruction
If synchronous mode is canceled between the specified spindles using
irrelevant whether this coupling is permanently configured or user defined. The leading and
following spindles can be at standstill or in motion when synchronous operation is
deactivated.
On switching off the synchronous mode with
mode. The originally programmed S-word is no longer valid for the FS, the following spindle
can be operated like any other normal spindle.
When the coupling is opened with
initiated internally in the control.

COUPOF variants
Three different methods can be used to deselect synchronous mode with
