Digitax ST Advanced User Guide 191
Issue Number: 1 www.controltechniques.com
The status of the CTNet network is displayed in the CTNet diagnostic parameter. When the Motion Processor is communicating successfully on the
CTNet network the number of messages per second is displayed.
If this parameter is set, then if the user attempts to download a new user DPL program or operating system to the Motion Processor and the drive is
enabled the download will be rejected and a run-time trip 70 will occur, if the global run-time trip parameter (Pr 17.14) is set.
Since downloading stops normal operations of the Motion Processor it may be considered unsafe to do this if the drive system is running, therefore
setting this parameter will prevent downloading under this condition.
When this parameter is 0 the drive will trip with runtime error 81 if an APC non-recoverable error occurs, such as use of an uninitialized CAM function.
When this parameter is 1 the drive will not trip when an APC non-recoverable error occurs
