What it means
A07473 is the EPOS message Beginning of traversing range reached: while traversing, the axis has moved to the limit of its traversing range. The manuals describe this message identically for G130, G150, S120 and S150. As an alarm it triggers no automatic drive reaction; depending on how the drive is configured, the same condition can also be issued as the fault F07473 instead, in which case the drive performs OFF1 (OFF2, OFF3).
Why it appears
- While traversing, the axis has moved to the limit of the traversing range — the beginning of the range has been reached.
What to check
- Move the axis away in the positive direction.
- If the condition was raised as the fault F07473 rather than as this alarm, acknowledge it as described under Reset and restart the drive.
Acknowledging and restarting
As an alarm, A07473 does not have to be acknowledged — the drive takes no automatic action on it. The same condition can also be configured as a fault (F07473); in that case the drive performs OFF1 (OFF2, OFF3) and the message is acknowledged IMMEDIATELY. In both cases the remedy is the same: move the axis away in the positive direction.
The same on every family
Every manual that describes A07473 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1561 |
| S120, S150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2825 |
