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.

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).
Description
Axis technology object
Start of the task with a positive edge
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".
