10.1 Safety functions
Safety functions protect the drive against permanent damage and partially result in the software switching off the drive (= disables).
Acknowledgement via IN A / IN B control inputs
The acknowledgement can be used to switch drive software back on ready for use, if it had to be disabled beforehand.
The acknowledgement via the IN A / IN B control inputs is only required if the corresponding parameter P06 is set to “manual acknowledgement”.
In the case of automatic acknowledgement the drive is ready to operate and run as soon as no error is set.
As soon as an error is detected the drive disables its output stages.
As long as the errors are set the drive remains disabled and no acknowledgement is accepted.
The acknowledgement made manually is achieved if
IN A / IN B = free-wheeling and then
a rising flank is detected at control input IN A
OR
a rising flank is detected at control input IN B.
The manually performed acknowledgement then monitors the IN A / IN B control inputs only if at least one error has occurred.
The manually performed acknowledgement acknowledges all errors that have occurred.
All error categories are defined in the troubleshooting chapter.
The acknowledgement switches the drive ready for operation 10 ms following a successful acknowledgement at the latest.
