What it means
A32461 is signaled when the input voltage of the analog sensor connected as Encoder 2 leaves the permissible limits on channel B. The drive stores an alarm value in r2124 that tells which measuring-range condition was detected. Depending on how the drive is configured, the same condition can also be signaled without any drive reaction.
Why it appears
- The input voltage of the analog sensor lies outside the permissible limits.
What to check
- Read the alarm value in r2124 and interpret it as a decimal number to see which condition applies.
- Alarm value 1 (input voltage outside the detectable measuring range): check the output voltage of the analog sensor.
- Alarm value 2 (input voltage outside the selected measuring range): check the voltage setting for each encoder period (p4675).
- Alarm value 3 (absolute value of the input voltage above the range limit): check the range limit setting and increase it if necessary (p4676).
Reading the message value
- The message value carries the alarm value, which is stored in r2124 and must be interpreted as a decimal number.
- 1: Input voltage outside detectable measuring range.
- 2: Input voltage outside the selected measuring range (p4675).
- 3: The absolute value of the input voltage has exceeded the range limit (p4676).
Parameters the manual names
- r2124 — holds the alarm value for this message; read it as a decimal number to determine which voltage condition was detected.
- p4675 — voltage per encoder period of analog sensor channel B; check this setting when the alarm value is 2.
- p4676 — range limit threshold of the analog sensor; check it and increase it if necessary when the alarm value is 3.
Acknowledging and restarting
No acknowledgment is required, and the drive does not respond automatically to this alarm. Once the input voltage of the analog sensor is back within the permissible limits — or p4675 and p4676 have been set correctly — the alarm goes away by itself. The same applies when the condition is configured to be signaled without a reaction.
The same on every family
Every manual that describes A32461 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Actual position/speed value incorrect or not available (11) | Encoder 2 | SINAMICS S120, S150 List Manual · p. 3111 |
| G130, G150 | NONE | NONE | Actual position/speed value incorrect or not available (11) | Encoder 2 | SINAMICS G130, G150 List Manual · p. 1788 |

Questions technicians ask
What does alarm A32461 mean on a SINAMICS drive?
It reports that the input voltage of the analog sensor connected as Encoder 2 on channel B is outside the permissible limits. The alarm value in r2124 shows which limit was exceeded.
How do I clear alarm A32461?
No acknowledgment is needed; the alarm removes itself once the voltage is back in range. Depending on the alarm value, check the sensor output voltage, the voltage per encoder period (p4675) or increase the range limit (p4676).
Which parameter tells me what triggered A32461?
r2124, read as a decimal number: 1 means the input voltage is outside the detectable measuring range, 2 outside the selected measuring range (p4675), and 3 that the absolute value has exceeded the range limit (p4676).
Does A32461 stop the drive?
No, the drive does not respond automatically to this alarm. Depending on the configuration, the same condition can also be signaled without any reaction.
