Siemens A01691 fault code meaning

Series: S110

SI Motion: Ti and To are not suitable for the DP cycle

servo drive

Meaning: The configured PROFIBUS communication time is incorrect, and the DP cycle is used as the actual value sampling cycle for the safety motion monitoring function. Isochronous PROFIBUS: The sum of Ti and To is too large for the configured DP cycle. The DP cycle must exceed the sum of Ti and To by at least 1 current loop cycles. Non-isochronous PROFIBUS: The DP cycle must be at least 4 times the current loop cycle.

Series: S210

SI motion: Ti and To are not suitable for the PN cycle

servo drive

Meaning: The configured PROFINET communication time is incorrect, and the PN cycle is used as the actual value sampling cycle for the safe motion supervision functions. Isochronous PROFINET: The sum of Ti and To is too large for the configured PN cycle. The PN cycle must exceed the sum of Ti and To by at least 1 current loop cycles. Non-isochronous PROFINET: The PN cycle must be at least 4 times the current loop cycle. Note: Ignoring this alarm may occasionally trigger message A01711 or A30711 with a message value of 1020 ... 1021.
