A07469 — EPOS: Traversing block < target position < software limit switch minus

A07469 is an alarm of the EPOS positioning function. It reports that in one of the traversing blocks the specified absolute target position lies outside the range limited by the software limit switch minus, i.e. the block is parameterized with a target position below the minus limit. The alarm identifies the offending block itself: the alarm value in r2124, interpreted as a decimal number, is the number of the traversing block with the illegal target position. Both manuals that describe this alarm state the same condition, so the same explanation applies regardless of the converter family.

• A traversing block is parameterized with an absolute target position that lies outside the range limited by the software limit switch minus.

1. Read the alarm value in r2124 and interpret it as a decimal number to identify the traversing block whose target position is illegal.
2. Correct the traversing block.
3. Alternatively, change the software limit switch minus; the remedy names p2578 and p2580 for this.

• The alarm value can be read in r2124; interpret it as a decimal number.
• It gives the number of the traversing block with the illegal target position.

• r2124 — alarm value; read it as a decimal number to find the traversing block with the illegal target position.
• p2578 — CI: EPOS software limit switch minus signal source; named by the remedy as a place to change the software limit switch minus.
• p2580 — CO: EPOS software limit switch minus; named by the remedy together with p2578 for changing the software limit switch minus.

No drive reaction is triggered and no acknowledgement is required for this alarm. It flags a parameterization error in the EPOS traversing block data; the remedy is to correct the traversing block or to change the software limit switch minus (p2578, p2580).
