IPOS-ILLOP

Was bedeutet F-10 ?

An IPOS program execution fault has occurred, caused by an incorrect command, invalid conditions during program run, or an attempt to use a function not implemented in the inverter. This can lead to unexpected program behavior and a halt of drive operation, impacting automation sequences.

• Syntax error or logical error in the IPOS program (inverter positioning and sequence control) loaded into the inverter.
• Attempting to execute an IPOS command or function that is not supported by the specific firmware version or hardware variant of the inverter.
• Invalid or out-of-range data passed to an IPOS instruction (e.g., motion target beyond limits), leading to an arithmetic overflow or address error.
• Memory corruption within the IPOS program storage area, potentially due to EMC disturbance or failed write operation.
• External I/O (Input/Output) conditions not met as expected by the IPOS program logic, causing a conditional instruction to fail.

1. 1

   Review the IPOS program logic line by line using the inverter's programming software for syntax errors, incorrect commands, or out-of-range values.

2. 2

   Verify the inverter's firmware version against the IPOS program's compatibility requirements using the firmware information parameter (e.g., P0-98).

3. 3

   Download the IPOS program again to the inverter from a known good source file to rule out transfer errors or memory corruption.

4. 4

   Simplify the IPOS program to a minimal, known-working sequence to isolate the problematic instruction or logic block.

5. 5

   Check the status of all digital and analog inputs referenced by the IPOS program using diagnostic parameters (e.g., P7-00, P7-01) to ensure correct values.
