Siemens A01666 fault code meaning
Siemens / A01666
Series: G115D, G120-CU240B-E-2, G130-G150, S120-S150
SI motion P1 (CU): Static 1 signal on F-DI for safety response
converter
Meaning: The logic 1 signal remains present for more than 10 seconds at F-DI configured in p10006. If no acknowledgment is given at F-DI for safety acknowledgment, a static logic 0 signal must be present. This prevents unintended safety acknowledgment (or the "Internal event acknowledgment" signal) in the event of an open circuit or vibration at either of the two digital inputs.

Series: G120-CU250S-2
SI motion P1: Static 1 signal for safety response on F-DI
converter
Meaning: At the F-DI set in p10006, the logic 1 signal has persisted for more than 10 seconds. If no acknowledgment is provided at the F-DI used for safety acknowledgment, a static logic 0 signal must be present. This prevents unintended safety acknowledgment (or the "Acknowledge internal event" signal) if an open circuit occurs or one of the two digital inputs bounces.

servo drive
Meaning: The logic 1 signal remains present for more than 10 seconds at F-DI configured in p10006. If no acknowledgment is given at F-DI for safety acknowledgment, a static logic 0 signal must be present. This prevents unintended safety acknowledgment (or the "Internal event acknowledgment" signal) in the event of an open circuit or vibration at either of the two digital inputs.
