MC_Reset (Confirm error) instruction

Table 9- 30 MC_Reset instruction
LAD / FBD
STEP 7 automatically creates the DB when you insert the instruction.
1
In the SCL example, "MC_Reset_DB" is the name of the instance DB.
2
The MC_Reset task cannot be aborted by any other motion control task. The new MC_Reset
task does not abort any other active motion control tasks.

To acknowledge an error with MC_Reset, follow these steps:
1. Check the requirements indicated above.
2. Start the acknowledgement of the error with a rising edge at the Execute input parameter.
3. The error has been acknowledged when Done equals TRUE and the technology object

Description
Use the MC_Reset instruction to acknowledge
"Operating error with axis stop" and
"Configuration error". The errors that require
acknowledgement can be found in the "List of
ErrorIDs and ErrorInfos" under "Remedy".
Before using the MC_Reset instruction, you
must have eliminated the cause of a pending
configuration error requiring acknowledgement
(for example, by changing an invalid
acceleration value in "Axis" technology object
to a valid value).
As of V3.0 and later, the Restart command
allows the axis configuration to be downloaded
to the work memory in the RUN operating
mode.
Description
Axis technology object
Start of the task with a positive edge
TRUE = Download the axis configuration from the load memory to the
work memory. The command can only be executed when the axis is
disabled.
FALSE = Acknowledges pending errors
TRUE = Error has been acknowledged.
TRUE = The task is being executed.
TRUE = An error has occurred during execution of the task. The
cause of the error can be found in parameters "ErrorID" and
"ErrorInfo".
Error ID for parameter "Error""
Error info ID for parameter "ErrorID"
