What it means
A07472 is an EPOS alarm that points to a parameterization problem in one traversing block: the block uses the positioning mode ABS_POS or ABS_NEG, but the modulo correction is not activated. With the modulo correction deactivated, the traversing block ABS_POS/ABS_NEG is not possible, i.e. the drive cannot carry out this block as it is parameterized. The alarm value tells you which traversing block is affected. The manuals describe the same cause for all drive objects, so the condition itself is written here once.
Why it appears
- The traversing block is parameterized with the positioning mode ABS_POS or ABS_NEG.
- At the same time, the modulo correction is not activated — in this state the traversing block ABS_POS/ABS_NEG is not possible.
What to check
- Read the alarm value in r2124 and interpret it as a decimal number: it contains the number of the traversing block with the illegal positioning mode.
- Correct this traversing block — the remedy in the manual is
Correct the traversing block.
— so that the positioning mode ABS_POS or ABS_NEG is no longer parameterized with the modulo correction deactivated.
Reading the message value
- The drive fills the message value (%1) with the number of the traversing block in which the positioning mode ABS_POS or ABS_NEG is parameterized illegally.
- This value is the alarm value in r2124; the manual specifies that it is interpreted decimal.
Parameters the manual names
- r2124 — alarm value: read it for this alarm as a decimal number; it gives the number of the traversing block whose positioning mode has to be corrected.
Acknowledging and restarting
No acknowledgement is required, and the drive does not react automatically to this message. It is enough to correct the traversing block identified by the alarm value in r2124.
The same on every family
Every manual that describes A07472 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does SINAMICS alarm A07472 mean?
A traversing block of the EPOS function is parameterized with the positioning mode ABS_POS or ABS_NEG while the modulo correction is not activated; in this state the traversing block is not possible.
How do I find the traversing block that triggers A07472?
The alarm value in r2124 contains the number of the affected traversing block. Interpret the value as a decimal number, then correct that traversing block.
Does A07472 have to be acknowledged?
No. The drive requires no acknowledgement for this alarm; it is resolved by correcting the parameterization of the traversing block.
Can I use ABS_POS or ABS_NEG without modulo correction?
No. The drive raises A07472 exactly when one of these positioning modes is parameterized in a traversing block while the modulo correction is not activated.
