SYNCAXES - Axes movement synchronization

The purpose of this command is to enable or disable the synchronization of simultaneous motion of two machine axes (for example left and right spindle rotation axes on a double spindles lathe machine).

Command: SYNCAXES ON(71) | OFF(72), FirstAxisID(Axis1), SecondAxisID(Axis2)

Access from sppx

Handler: program SyncAxes

Parameter CLD array Description
IsOn CLD[1] New state of the synchronization: 71 - Axes synchronization is active. 72 - Axes motion synchronization is disabled.

Parameters available through the cmd operator

Parameter Type Description
Action Integer Toggle control that modifies the synchronization state (enabled/disabled): 1 - Set synchronization state to enabled. 0 - Set synchronization state to disabled.
Axis1 String String identifier for the first of the two axes to be synchronized.
Axis2 String String identifier for the second of the two axes to be synchronized.

Here is a simple example of program handler for this command:

program SyncAxes
  Outblock
  a1: String;
  a1 = cmd.Str["Axis1"];
  a2: String;
  a2 = cmd.Str["Axis2"];
  if (a1="AxisCPos") or (a2="AxisCPos") or (a1="AxisC1Pos") or (a2="AxisC1Pos") then begin
    if CLD.IsOn=71 then begin
      GSyncSpeeds = 288; GSyncSpeeds@ = Maxreal;
      Formblock;
      Output Outstr$ + " (Sync spindles rotation)";
      Phase = C2-C; Phase@=MaxReal;
      GSyncPhase = 289; GSyncPhase@=0;
      FormBlock;
      output OutStr$ + " (Sync phase)";
    end else begin
      GsyncSpeeds = 290; GsyncSpeeds@ = Maxreal;
      Formblock;
      Output Outstr$ + " (Cancel spindles sync)";
    end;
  end;
end

Access from .NET

Handler:

public override void OnSyncAxes(ICLDSyncAxesCommand cmd, CLDArray cld)

Inheritance: ICLDSyncAxesCommand : ICLDCommand.

Read the parameters from the strongly-typed cmd object (recommended); the raw cld[i] array (same indices as in sppx) and the named cmd["..."] helpers are available too. The table lists the command's members, including those inherited from its base interfaces; the common ICLDCommand members (navigation, CLD, CLDFile, TechOperation, ...) are described in the CLData access model.

Member Type Description
cmd.IsOn bool Contains "true" if the command enables a mode of synchronous movement, otherwise it is "false".
cmd.IsOff bool Contains "true" if the command disables a mode of synchronous movement, otherwise it is "false".
cmd.FirstAxisID string Textual axis identifier for the first of the machine axes between which synchronization is performed.
cmd.SecondAxisID string Textual axis identifier for the second of the machine axes between which synchronization is performed.

Example - OnSyncAxes (from the Goodway SW postprocessor):

public override void OnSyncAxes(ICLDSyncAxesCommand cmd, CLDArray cld)
{
    if (SameText(CurrentOperation.TypeName, "TSTTakeoverMTM")) return;

    base.OnSyncAxes(cmd, cld);
    if (cmd.FirstAxisID.Contains("AxisC1") || cmd.FirstAxisID.Contains("AxisC2")){
        SyncSpindles(cmd.IsOn,false);
    }else
    if (cmd.FirstAxisID.Contains("AxisZ1") || cmd.FirstAxisID.Contains("AxisZ2")){
        SyncZ(cmd.IsOn, false);
    }else{
        Log.Error("Axes can not be syncronized: ("+cmd.FirstAxisID+","+cmd.SecondAxisID+")");      
    }
}
