What it means
A01304 is raised when the firmware version held in the drive's non-volatile memory is more recent than the firmware version in a connected DRIVE-CLiQ component. The alarm value identifies which component is affected. Depending on how the drive is configured, the same condition can also be signalled as a fault instead of as an alarm; in either case the drive takes no automatic reaction.
Why it appears
- The firmware version in the non-volatile memory is more recent than the firmware version in the connected DRIVE-CLiQ component.
What to check
- Read the alarm value in r2124, interpreting it as a decimal number: it contains the component number of the DRIVE-CLiQ component involved.
- Update the firmware of that component using p7828 and p7829 together with the commissioning software (commissioning tool).
Reading the message value
- The alarm value is stored in r2124 and is to be interpreted as a decimal number; it contains the component number of the DRIVE-CLiQ component involved.
Parameters the manual names
- r2124 — alarm value: for this alarm it holds the component number of the affected DRIVE-CLiQ component and is read as a decimal.
- p7828 — firmware download component number: specifies the component whose firmware is downloaded during the update.
- p7829 — activate firmware download: carries out the firmware download that updates the component.
Acknowledging and restarting
As an alarm, A01304 requires no acknowledgement. If the drive is configured to signal the same condition as a fault, that fault must be acknowledged immediately. The message is dealt with by updating the firmware via p7828 and p7829 with the commissioning software.
The same on every family
Every manual that describes A01304 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | NONE | General drive fault (19) | None | SINAMICS G130, G150 List Manual · p. 1398 |
| S120, S150 | NONE | NONE | General drive fault (19) | None | SINAMICS S120, S150 List Manual · p. 2588 |

Questions technicians ask
What does alarm A01304 mean on a SINAMICS drive?
The firmware version in the non-volatile memory is more recent than the firmware version in the connected DRIVE-CLiQ component. The alarm value in r2124, read as a decimal, gives the number of the component involved.
How do I clear A01304?
Update the firmware of the affected component using p7828 and p7829 together with the commissioning software (commissioning tool).
Does A01304 stop the drive?
No automatic reaction is triggered. As an alarm it needs no acknowledgement; if the drive signals the condition as a fault instead, that fault must be acknowledged immediately.
How do I find out which component A01304 refers to?
Read the alarm value in r2124 and interpret it as a decimal number — it is the component number of the DRIVE-CLiQ component involved.
