SlaveSync.syncstate cannot be changed to YES. When the MasterAxis starts to move, SlaveSync.syncstate changed to YES. Temporarily only occurs on virtual axes.

The following is the process when an abnormal situation occurs: ①When axis B is at standstill, call FB to trigger _enablecamming, and axis C can finish synchronization with axis B. ②When B and A are synchronized, and A-axis is running, then trigger normal stop. ③At this time, B-axis is desynchronized by _disablegearing, then the speed is reduced to 0 by _move, and finally _disableAxis, and similarly C-axis is desynchronized by _disablecamming, then the speed is reduced to 0 by _move, and finally _disableAxis. ④After resetting the fault, the program automatically completes the enabling of the 3 axes. ⑤At this point, when repeating step①, the syncstate of the synchronization object of C-axis can not be transformed to YES, and the B-axis must be moved for the transformation to occur.

I have found the cause: toAxisSync.setconfigdata.SyncingMotion.masterReversionTolerance . When this parameter is equal to 80, the phenomenon I described above occurs, not only that, if the Master is a formula technology object and the slave axis is synchronized with the Master gear, it is not only SlaveSync.syncstate=NO, but even if the output value of the formula technology object starts to change, it doesn't change to YES and the slave axis doesn't move. It is not clear if this affects the synchronization function of other technology objects. I did not find a description in the “Gear_TechnologyFct_en-US”, “Supplementary_TechnologyFct_en-US” manuals that would cause this result.

Please choose one which fits to your requirement. 2.2.5 Synchronization In order for the following axis to follow the master value according to the transmission function, the following axis must first be synchronized to the master value. The type of synchronization is determined from several assignable parameters/settings: • The synchronization criterion/synchronization position, which corresponds to the setting specified in the synchronizingMode parameter; the synchronization position on the master value side and/or the synchronization position on the slave value side are directly specified here or are derived from the synchronization criterion and, if necessary, the transmission function • The synchronization direction, the motion direction of the slave values during synchronization; can be set in the synchronizingDirection parameter • Position of synchronization range relative to synchronization position: Leading, trailing, or symmetrical synchronization; can be set in the syncPositionReference parameter • the reference of the synchronization profile; can be set in the syncProfileReference – Synchronization over a specifiable master value distance The synchronization length over the master value is specified in the synchronization command. – Synchronization profile via specifiable dynamic response parameters (time reference) The dynamic response parameters are specified in the synchronization command. .............. ................ 2.2.5.9 “Synchronous” status during synchronization https://support.industry.siemens.com/cs/ww/en/view/109818984

I will add some more in response to the information you provided. Here is my code： “ i32RetDINT[03]:= _enablecamming(followingobject := toAxisSync, direction := POSITIVE, mastermode := ABSOLUTE, slavemode := ABSOLUTE, cammingmode := CYCLIC, cam := Str_ACENAB.Cam, synchronizingmode := IMMEDIATELY, syncpositionreference := SYNCHRONIZE_WHEN_POSITION_REACHED, syncprofilereference := RELATE_SYNC_PROFILE_TO_TIME ,velocityType := direct ,velocity := 50.0 ,positiveAccelType := direct ,positiveAccel := 10000.0 ,negativeAccelType := direct ,negativeAccel := 10000.0 ,positiveAccelStartJerkType:= direct ,positiveAccelStartJerk := 50000.0 ,positiveAccelEndJerkType := direct ,positiveAccelEndJerk := 50000.0 ,negativeAccelStartJerkType:= direct ,negativeAccelStartJerk := 50000.0 ,negativeAccelEndJerkType := direct ,negativeAccelEndJerk := 50000.0 ,velocityProfile := SMOOTH, mergemode := IMMEDIATELY, nextcommand := IMMEDIATELY, commandid := CammingCommandId, synchronizingdirection := SHORTEST_WAY); ” You can see I used “syncprofilereference := RELATE_SYNC_PROFILE_TO_TIME” and “,velocityProfile := SMOOTH,”. As you can see in the screenshot I posted, the .state=camming has been there for a long time, but the .syncstate didn't shift, the .syncstate only shifted to YES when the Master Axis moved up. My temporary solution is to first change “toAxisSync.setconfigdata.SyncingMotion.masterReversionTolerance” to 0 when using the _enablecamming command, and when using _ enablegearing, and Master is an Axis technology object, change “toAxisSync.setconfigdata.SyncingMotion.masterReversionTolerance” to 40, else Otherwise, keep it at 0. Today local tech support gave me the advice is “syncingMotion.enableSyncWithinTolerance = YES”. My question is why a change in the .setconfigdata.SyncingMotion.masterReversionTolerance value would have this effect.
