What it means
Alarm A32460 reports that the voltage at the input of the analog sensor connected to Encoder 2 is outside the permissible limits, so channel A of the sensor is not delivering a usable signal. The drive stores an alarm value in r2124 that identifies which limit was violated. Depending on the drive configuration, the same condition can also be signaled with no reaction.
Why it appears
- The voltage present at the input of the analog sensor lies outside the limits the drive permits for channel A.
What to check
- Read the alarm value in r2124 (interpret it as a decimal number) to determine which of the three limits was violated.
- Alarm value 1: the input voltage is outside the detectable measuring range — check the output voltage of the analog sensor.
- Alarm value 2: the input voltage is outside the measuring range set in p4673 — check the voltage setting for each encoder period (p4673).
- Alarm value 3: the absolute value of the input voltage has exceeded the range limit (p4676) — check the range limit setting and increase it if necessary (p4676).
Reading the message value
- The drive stores the alarm value in r2124, interpreted as a decimal number; it names the violated limit:
- 1: Input voltage outside detectable measuring range.
- 2: Input voltage outside measuring range set in p4673.
- 3: The absolute value of the input voltage has exceeded the range limit (p4676).
Parameters the manual names
- r2124 — alarm value of this message; read it as a decimal number to see whether the detectable measuring range (1), the range set in p4673 (2) or the range limit p4676 (3) was exceeded.
- p4673 — Analog sensor channel A voltage per encoder period; for alarm value 2, check this voltage setting for each encoder period.
- p4676 — Analog sensor range limit threshold; for alarm value 3, check this range limit setting and increase it if necessary.
Acknowledging and restarting
This alarm requires no acknowledgement, and the drive takes no automatic reaction to it. The remedy is diagnostic only: follow the check that matches the alarm value in r2124 — the sensor output voltage, the p4673 voltage setting or the p4676 range limit.
What differs between the drive families
Straight from the manuals' own fields — A32460 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | NONE | Actual position/speed value incorrect or not available (11) | Encoder 2 | SINAMICS G130, G150 List Manual · p. 1788 |
| S120, S150 | — | — | Actual position/speed value incorrect or not available (11) | Encoder 2 | SINAMICS S120, S150 List Manual · p. 3110 |

Questions technicians ask
What does alarm A32460 mean on a SINAMICS drive?
The voltage at the input of the analog sensor connected to Encoder 2 is outside the permissible limits, so channel A of the sensor is not delivering a usable signal. Depending on the configuration, the same condition can also be signaled with no reaction.
How do I fix alarm A32460?
Read the alarm value in r2124 as a decimal number. Value 1: check the output voltage of the analog sensor; value 2: check the voltage setting for each encoder period in p4673; value 3: check the range limit setting in p4676 and increase it if necessary.
Does alarm A32460 have to be acknowledged?
No. The manuals specify no acknowledgement and no automatic drive reaction for this message; correct the voltage condition at the sensor instead.
Where is the alarm value of A32460 stored?
In r2124, to be interpreted as a decimal number. 1 means the input voltage is outside the detectable measuring range, 2 outside the measuring range set in p4673, and 3 that its absolute value exceeded the range limit in p4676.
