What it means
Alarm A13031 tells you that one of the available periods of the Trial License function has expired. The Control Unit issues the alarm; the drive does not react to it automatically and no acknowledgement is needed. What the alarm asks for is a licensing decision: start another trial period, deactivate the functions that require a license, or license the drive unit properly. The neighbouring Trial License alarms — A13030, A13032 and A13033 — cover the other stages of the trial license and are described on their own pages.
Why it appears
- A period that was granted for the Trial License function has run out.
What to check
- Read the Trial License status in r9919 to see the licensing state the Control Unit is reporting.
- If required, start an additional period by setting p9918 = 1.
- Deactivate the functions that require a license.
- Alternatively, license the drive unit appropriately.
Parameters the manual names
- p9918 (Licensing active Trial License) — set to 1 here to start an additional Trial License period.
- r9919 (Licensing Trial License status) — read here which status the Trial License function currently reports.
Acknowledging and restarting
No acknowledgement step is required for this alarm; it is settled by one of the remedies above. The manual adds a caution: A license that is not adequate will only become evident after the next time the system runs up.
