Error Management

When a non-fatal error occurs and motion must be stopped quickly, the following procedure can be taken:

For each axis:

Step	Example Application Code
Send Stop Command for each axis	MLAxisStop(PipeNetwork.AXI_A1_Axis, TRUE, DEF_A1_StopDec);
Stop the Axis Motion Generator	MLAxisMoveVel(PipeNetwork.AXI_A1_Axis, 0.0);
Wait for Axis to be stopped	AxisStatus := MLAxisStatus(PipeNetwork.AXI_A1_Axis); IF AxisStatus.11 THEN MLAxisStop(PipeNetwork.AXI_A1_Axis,FALSE,DEF_A1_StopDec);
Turn power off(disable) all the axes	MLAxisPower(PipeNetwork.AXI_A1_Axis,FALSE);
Disconnect Pipe Network from the axis	MLCNVDisconnect(PipeNetwork.CNV_A1);

For the machine:

Step	Example Application Code
Stop Command at the master block level	MLMstRun(PipeNetwork.MASTER, 0.0);
Wait for Master command to be stopped	IF A1_AckState = DEF_StateErrorStop    AND A2_Ackstate = DEF_StateErrorStop    AND MLBlkIsReady(PipeNetwork.MASTER) THEN PrintF('*** ErrorStop M1=%i ***', M1_StatusWord,0,0,0);    M1_AckState := DEF_StateErrorStop;

This procedure for error management is based on the Project Structure Guidelines as described in Application Software Structure - Implementation
