What it means
A07505 appears when an EPOS traversing block with the "fixed stop" task is to be executed while the drive is in the U/f/SLVC mode. This combination is not possible: the traversing block task "fixed stop" cannot be carried out in this operating mode. The alarm value identifies the traversing block concerned.
Why it appears
- A traversing block with the "fixed stop" task was to be executed while the drive was in the U/f/SLVC mode; this task cannot be executed in that mode.
What to check
- Read the alarm value in r2124 as a decimal number — it gives the number of the traversing block with the illegal task parameter.
- Check this traversing block and change the task set in it (p2621).
- If the "fixed stop" task is nevertheless required, change the open-loop/closed-loop control operating mode (p1300), because the task cannot be executed in the U/f/SLVC mode.
Reading the message value
- The drive enters the alarm value in r2124; interpret it as a decimal number.
- It contains the number of the traversing block with an illegal task parameter.
Parameters the manual names
- r2124 — alarm value; read it as a decimal number to identify the traversing block whose task parameter is illegal.
- p2621 — EPOS traversing block task; the task of the affected traversing block is set here and must be changed.
- p1300 — open-loop/closed-loop control operating mode; change this mode if the "fixed stop" task is to be used.
Acknowledging and restarting
This alarm requires no acknowledgement. It is resolved by removing the cause: change the task of the traversing block named in r2124 or change the operating mode in p1300 so that the "fixed stop" task is no longer executed in the U/f/SLVC mode.
The same on every family
Every manual that describes A07505 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does alarm A07505 mean on a SINAMICS drive?
An EPOS traversing block with the "fixed stop" task was to be executed while the drive was in the U/f/SLVC mode; this task is not possible there.
How do I find the traversing block that triggers A07505?
Read the alarm value in r2124 as a decimal number — it is the number of the traversing block with the illegal task parameter.
How do I clear alarm A07505?
Check the traversing block and change its task (p2621), or change the open-loop/closed-loop control operating mode (p1300) if the fixed stop task is required.
Does A07505 have to be acknowledged?
No. The alarm requires no acknowledgement; it is resolved by correcting the traversing block task or the operating mode.
