What it means
A35807 is reported by a Terminal Module (TM) — for example a TM15, TM17 or TM41 — on a SINAMICS S120 or S150. The drive monitors the time in which the sequence control on the Terminal Module runs, and the module has signalled an error: a timeout in this sequence control. Depending on how the drive is configured, the same condition can also be output as a fault or as a message that triggers no reaction.
Why it appears
- A timeout has occurred in the sequence control on the Terminal Module; the module reports this as an error.
What to check
The manual describes no intermediate checks — its only remedy is:
- Replace the Terminal Module.
Acknowledging and restarting
As an alarm the message requires no acknowledgement and the drive does not perform an automatic stop; the message clears once the faulty Terminal Module has been replaced. If the drive is configured to output the same condition as a fault, the fault is acknowledged IMMEDIATELY (POWER ON)
. In the variant that triggers no reaction, no acknowledgement is required either.
The same on every family
Every manual that describes A35807 gives it the same reaction, acknowledgement and message class.
