Comments

The choke Abort Method will try to cancel any active choke Move or Step commands. If no Move or Step command is in progress, the command will be ignored and return successful. The Method will complete when the command has been accepted. The abort operation may or may not have completed when the Method returns. The Method returns errors only if the operation cannot be started. The Client shall monitor the Moving and if provided the CommandRejected Variables to determine if the abort was successful or failed. Table 45 specifies the AddressSpace representation for the choke Abort Method.
