201016 <location>CF card corrupt

Acknowledge: NONE
Cause: At least one file in the directory /SIEMENS/SINAMICS has been illegally changed with
respect to the state when originally supplied.

Remedy: Restore the state of the CF card when originally supplied
201030 <location>Monitoring master control: Sign-of-life failure PC
Reaction: OFF1
Acknowledge: IMMEDIATELY
Cause: For active PC master control, no sign-of-life was received within the monitoring time.
The master control was returned to the active BICO interconnection.
Remedy: Set the monitoring time higher at the PC/AOP or disable completely.
Notice:
The monitoring time should be set as short as possible. A long monitoring time means a
late response when the communications fail!
The monitoring time is set in milliseconds.
- in the AOP using the Main menu -> Settings -> Control settings -> Timeout monitoring
- In STARTER using <Drive> -> Commissioning -> Control panel -> Button "Fetch master
control" -> a window is displayed in which the monitoring time can be set.
201035 <location>ACX: Run-up from the back-up files
Reaction: NONE
Acknowledge: NONE
Cause: When the control unit ran-up no complete data set from the parameter save files was
found. The last time that the parameterization was saved, it was not completely carried-
out. Instead, a backup data set or file is downloaded.
Alarm value (r2124, hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: If you saved the project in STARTER, download your project again and save using the
function "Copy RAM to ROM" or with p0977 = 1. This means that all of the parameter files
are again completely written into the CompactFlash Card.
201036 <location>ACX: Parameter back-up file missing
Reaction: A_INFEED: NONE (OFF2)
SERVO: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
