What it means
A36217 is the hub undervoltage alarm: the 24 V power supply on the DRIVE-CLiQ Hub Module has undershot the alarm threshold. The alarm is reported for the component Terminal Board (TB). When it is raised, the drive stores the operating voltage actually present in r2124. The drive itself takes no automatic action in response to this alarm; depending on how the drive is configured, the same condition can also be signalled with no reaction (N).
Why it appears
- The 24 V power supply on the DRIVE-CLiQ Hub Module has undershot the alarm threshold.
What to check
- Read the alarm value in r2124 — interpreted as a decimal number, it shows the operating voltage that was actually present when the alarm was raised.
- Check the supply voltage of the component involved.
- Replace the component involved.
Reading the message value
- The message value carries the alarm value from r2124, which the manual says to interpret as a decimal number:
Actual operating voltage in 0.1 °C resolution
.
Parameters the manual names
- r2124 (alarm value) — for this alarm it holds the operating voltage actually present at the hub when A36217 was raised; interpret the value as a decimal number.
Acknowledging and restarting
This alarm requires no acknowledgment. It goes away by itself once the 24 V power supply of the hub has recovered above the alarm threshold.
The same on every family
Every manual that describes A36217 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |

| S120, S150 | NONE | NONE | Supply voltage fault (undervoltage) (3) | Terminal Board (TB) | SINAMICS S120, S150 List Manual · p. 3250 |
| G130, G150 | NONE | NONE | Supply voltage fault (undervoltage) (3) | Terminal Board (TB) | SINAMICS G130, G150 List Manual · p. 1912 |

Questions technicians ask
What does alarm A36217 mean on a SINAMICS drive?
It is the hub undervoltage alarm: the 24 V power supply on the DRIVE-CLiQ Hub Module has undershot the alarm threshold. The operating voltage present at that moment is stored in r2124.
How do I fix A36217?
Check the supply voltage of the component involved, and replace the component involved if the alarm persists. The voltage present when the alarm was raised can be read in r2124.
Does A36217 stop the drive?
No. The drive takes no automatic action in response to this alarm; depending on the configuration, the same condition can also be signalled with no reaction (N).
Does A36217 have to be acknowledged?
No. The alarm clears itself once the 24 V supply of the hub has recovered above the alarm threshold.
