What it means
C01798 is a safety message of the Safety Integrated (SI) motion monitoring functions: it is issued while the drive is executing the forced checking procedure (test stop) for these functions. The message only reports that this check is in progress at the moment. Once the test stop has been completed, the drive withdraws the message by itself.
Why it appears
- The drive is currently running the forced checking procedure (test stop) for the safe motion monitoring functions.
What to check
- No remedy is necessary. The message is withdrawn automatically as soon as the test stop has been completed.
Acknowledging and restarting
No action is required. The drive automatically withdraws the message when the test stop has been completed, so it does not have to be cleared by hand.
