What it means
F50510 is raised when the run-time groups of the free function blocks (FBLOCKS) attempt to log on with the sampling time management and the logon of at least one run-time group is rejected. The reason the manuals give: too many different hardware sampling times may have been assigned to the free function blocks, so one of the groups cannot be accommodated.
Why it appears
- Too many different hardware sampling times were assigned to the free function blocks, so the sampling time management rejected the logon of at least one run-time group.
What to check
- Check the number of available hardware sampling times (T_sample below 8 ms) in r7903 — the parameter shows how many hardware sampling times are still assignable.
Parameters the manual names
- r7903 — shows the hardware sampling times still assignable (HW t_samp free); for this fault it tells you whether the free function blocks still have an assignable hardware sampling time with T_sample below 8 ms.
Acknowledging and restarting
The drive is switched off (OFF2) and this fault must be acknowledged IMMEDIATELY before the drive can be started again.
What differs between the drive families
Straight from the manuals' own fields — F50510 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G120XA | OFF2 | IMMEDIATELY | — | — | SINAMICS G120XA PN converter · p. 1168 |
| G120 | OFF2 | IMMEDIATELY | General drive fault (19) | — | SINAMICS G120 · p. 934 |
The drives this code lives on
F50510 is described for G120, G120XA. These are the converters of those families in our catalogue — price on request.
Questions technicians ask
What does fault F50510 mean?
The sampling time management rejected the logon of at least one run-time group of the free function blocks (FBLOCKS). The manuals name too many different hardware sampling times assigned to the free function blocks as the possible cause.
How do I clear fault F50510?
Check the number of available hardware sampling times in r7903, where the condition to verify is T_sample below 8 ms, and then acknowledge the fault IMMEDIATELY.
Which parameter belongs to fault F50510?
r7903. It shows how many hardware sampling times are still assignable (HW t_samp free) and is exactly the value the remedy asks you to check.
How is F50510 acknowledged?
The fault is acknowledged IMMEDIATELY. The drive is switched off (OFF2) while the fault is active and can be started again after the acknowledgement.
