Block %2 Axis/Spindle %3 Synchronism Override Not Possible; Block %2 Axis/Spindle %3 'Correct Synchronism' Is Being Ignored - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
Definitions: The determination of the offset value ($AA_COUP_CORR[Sn]) intended by the NC/PLC signal
<Synchronlauf_nachfuehren/> (correct synchronism) cannot be executed. The offset value cannot be calculated prop-
erly. The reasons for this may be:
- Reason 1: The following axis is not configured as a spindle.
- Reason 2: The coupling has more than one active leading axis.
- Reason 3: The leading axis is not configured as a spindle.
- Reason 4: The coupling factor (the quotient from CPLNUM and CPLDEN) is neither 1 nor -1.
- Reason 5: CPLSETVAL = "cmdvel".
- Reason 6: An independent motion component of the following spindle is active (VDI interface signal DB31..,
DBX98.4 = 1).
- Reason 7: There is no following spindle synchronism on the setpoint side.
- Reason 8: The synchronism on the setpoint side has decreased again.
- Reason 9: The following or leading spindle is a link axis (NCU_LINK).
Reaction: Alarm display.
Remedy: The following remedies are available for the indicated reasons:
- Reasons 1 to 5: The coupling has to be reconfigured/reprogrammed.
- Reasons 6 and 7: Wait until VDI interface signals DB31.., DBX99.4 'Synchronization running' = 0 and DB31..,
DBX98.4 'Overlaid movement' = 0 before setting VDI interface signal DB31..,DBX31.6 'Correct synchronism'.
- Reason 8: Wait until the following axle/spindle can follow the leading values before setting VDI interface signal
DB31.., DBX31.6 'Correct synchronism'.
Program Clear alarm with the Delete key or NC START.

22036 [Channel %1: ] Block %2 Axis/spindle %3 Synchronism override not possible (reason
%4)
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis/spindle number
%4 = Reason
Definitions: The synchronism override intended by setting the VDI interface signal DB31..,DBX31.6 'Correct synchronism' or writ-
ing variable $AA_COUP_CORR[Sn] cannot currently be considered. The reasons may be:
- Reason 1: Reference point approach or zero mark synchronization for spindles is active.
- Reason 2: Deletion of synchronism override is active.
- Reason 3: Writing is not allowed.
Reaction: Alarm display.
Remedy: Wait until the conditions for override value processing are available again prior to setting VDI interface signal
DB31..,DBX31.6 'Correct synchronism' or writing variable $AA_COUP_CORR[Sn]:
- Reason 1: Reference point approach / zero mark synchronization completed.
- Reason 2: Deletion of synchronism override completed.
- Reason 3: Writing allowed.
Program Clear alarm with the Delete key or NC START.
Continuation:
22037 [Channel %1: ] Block %2 Axis/spindle %3 'Correct synchronism' is being ignored
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis/spindle number
Definitions: VDI interface signal DB31..,DBX31.6 'Correct synchronism' is being ignored, because VDI interface signal
DB31..,DBX31.7 'Delete synchronism override' has been set.
Reaction: Alarm display.
Remedy: Reset the two VDI interface signals DB31..,DBX31.7 'Delete synchronism override' and DB31..,DBX31.6 'Correct syn-
chronism', before the latter signal can be set again.
Program Clear alarm with the Delete key or NC START.
