MC_Reset: Acknowledge fault, restart technology object as of V6

Description

Motion Control instruction "MC_Reset" can be used to acknowledge "Operating error with axis stop" and "Configuration error". The errors that require acknowledgment can be found in the "List of ErrorIDs and ErrorInfos" under "Remedy".

The axis configuration can be downloaded to the work memory after a download in RUN mode.

Requirements

The positioning axis technology object has been configured correctly.
The cause of a pending configuration error requiring acknowledgment has been eliminated (for example, acceleration in positioning axis technology object has been changed to a valid value).

Override response

The MC_Reset command cannot be aborted by any other Motion Control command.

The new MC_Reset command does not abort any other active Motion Control commands.

Parameters

Parameter	Declaration	Data type	Default value	Description
Axis	INPUT	TO_Axis	-	Axis technology object
Execute	INPUT	BOOL	FALSE	Start of the command with a positive edge
Restart	INPUT	BOOL	FALSE	TRUE	Download the axis configuration from the load memory to the work memory. The command can only be executed when the axis is disabled. Refer to the notes on Download to the CPU.
Restart	INPUT	BOOL	FALSE	FALSE	Acknowledges pending errors
Done	OUTPUT	BOOL	FALSE	TRUE	Error has been acknowledged.
Busy	OUTPUT	BOOL	FALSE	TRUE	The command is being executed
Error	OUTPUT	BOOL	FALSE	TRUE	An error occurred during execution of the command. The cause of the error can be found in parameters "ErrorID" and "ErrorInfo".
ErrorID	OUTPUT	WORD	16#0000	Error ID for parameter "Error"
ErrorInfo	OUTPUT	WORD	16#0000	Error info ID for parameter "ErrorID"

Acknowledging an error requiring acknowledgment with MC_Reset

To acknowledge an error, follow these steps:

Check the requirements indicated above.
Start the acknowledgment of the error with a rising edge at input parameter "Execute". With MC_Reset as of V7.0 or higher you can acknowledge switch-on prevention errors on the configured encoder or drive before the axis is enabled.
If output parameter "Done" indicates the value TRUE and tag of technology object <Axis name>.StatusBits.Error the value FALSE, the error has been acknowledged.

Note

Acknowledge with "Restart" = FALSE

To acknowledge only the errors, set "Restart" = FALSE. The technology object cannot be used during a restart. All errors at axes and encoders are acknowledged even if they are not enabled or active.
