What it means
A07474 is the EPOS message «End of traversing range reached»: while traversing, the axis has arrived at the limit of its traversing range. As an alarm the drive takes no automatic action — it only reports the position, and no acknowledgment is needed. Depending on the drive's configuration, the same condition can also be issued as a fault; in that case the drive switches off with OFF1 (OFF2 or OFF3 can apply instead) and the fault must be acknowledged immediately before a restart.
Why it appears
- While traversing, the axis has reached the limit of its traversing range.
What to check
- Move the axis away from the limit by traversing in the negative direction.
- If the drive raised the condition as a fault rather than an alarm, acknowledge it immediately and then restart the drive.
Acknowledging and restarting
The alarm itself needs no acknowledgment. If the condition is output as a fault, the drive reacts with OFF1 (OFF2, OFF3) and must be acknowledged immediately; it can then be restarted.
The same on every family
Every manual that describes A07474 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does SINAMICS alarm A07474 mean?
It is the EPOS message «End of traversing range reached»: during traversing, the axis has moved to the limit of its traversing range.
How do I clear A07474?
Move the axis away in the negative direction. The alarm itself requires no acknowledgment; if the drive has raised the condition as a fault, acknowledge it immediately.
Does A07474 stop the drive?
As an alarm, no — the drive takes no automatic reaction. If the condition is issued as a fault, the drive reacts with OFF1 (OFF2, OFF3) and must be acknowledged immediately.
