MC_Halt Overview
Element Name | Element Type | Description |
---|---|---|
Execute | Input | Edge detected request to execute the function block. |
Axis | Input/Output | Axis reference variable. This can not be a constant. |
Deceleration | Input | Specify the deceleration of the stop move. |
Jerk | Input | Specify the change in rate of deceleration (unit/second3). |
BufferMode | Input | Specify the sequential operation setting of the function block. See BufferMode Table. |
Done | Output | Indicates the operation of the function block is finished. |
Busy | Output | Indicates the function block is currently being executed. |
Active | Output | Indicates the function block is controlling the selected axis. |
CommandAborted | Output | Indicates the function block execution was aborted. |
Error | Output | Indicates whether an error occurs or not. |
ErrorID | Output | Error Identification number. |

Value | Buffer Mode | Description |
---|---|---|
0 | Aborting | Abort previous command and execute the command immediately. |
1 | Buffered | Execute the command after previous command is completed. |
2 | BlendingLow | The new command is blended into a previously executed command using the lower velocity value when comparing the previous command and new command. |
3 | BlendingPrevious | The new command is blended into a previous command using the velocity of the previous command. |
4 | BlendingNext | The new command is blended into a previous command using the velocity from the new command. |
5 | BlendingHigh | The new command is blended into a previous command using the higher velocity value when comparing the previous command and new command. |
