What it means
A09000 is an alarm that the Control Unit (CU) raises when the drive's web server users are misconfigured. For S120 and S150 the manual describes it as Web server user incorrectly configured
— an error occurred while a web server user was being configured. For G130 and G150 the same alarm is described specifically as Webserver security: password for "Administrator" user not set
. No automatic response is triggered and no acknowledgement is needed: the alarm disappears once the user configuration has been corrected.
Why it appears
- The web server user configuration is faulty: an error occurred while configuring a web server user (the wording used for S120/S150). Which of the possible errors applies is shown by the fault value in r0949.
- On G130/G150 the cause is given directly: the password for the user "Administrator" has not been set.
What to check
- Read the fault value in r0949 as a decimal number to identify the case: 0 = no admin password, 1 = invalid admin password, 2 = invalid SINAMICS password.
- Correct the user configuration of the web server.
- Enter a correct password — for the G130/G150 case, enter the password for the user "Administrator".
Reading the message value
- The fault value in r0949, interpreted as a decimal number, identifies the error:
- 0 — No admin password.
- 1 — Invalid admin password.
- 2 — Invalid SINAMICS password.
Parameters the manual names
- r0949 — fault value: read it as a decimal number to see which web server user configuration error triggered A09000 (no admin password, invalid admin password or invalid SINAMICS password).
Acknowledging and restarting
A09000 needs no acknowledgement. Correct the web server user configuration and enter a valid password — on G130/G150, the password for the user "Administrator" — and the alarm goes away by itself.

Questions technicians ask
What does SINAMICS alarm A09000 mean?

How do I clear A09000?
Correct the web server user configuration and enter a correct password — for the G130/G150 case, enter the password for the user "Administrator". No acknowledgement is needed; the alarm clears itself once the configuration is fixed.
What do the A09000 fault values 0, 1 and 2 mean?
Read as a decimal value in r0949: 0 means no admin password, 1 an invalid admin password and 2 an invalid SINAMICS password.
