Reaction: NONE
Acknowledge: POWER ON
Cause: Module booting was interrupted several times.
Possible reasons for booting being interrupted:
- POWER OFF of the module.
- CPU crash.
- USER data invalid.
After this fault is output, then the module is booted with the factory settings.
Remedy: Power down the module and power it up again.
Note:
After switching on, the module reboots from the USER data (if available).
If the fault situation is repeated, then this fault is again output after several interrupted boots.

Acknowledge: NONE
Cause: The write access to the removable data medium was unsuccessful.
Remedy: Remove and check the removable data medium. Then run the data backup again.
A01020 Write to RAM disk unsuccessful

Acknowledge: NONE
Cause: The write access to the internal RAM disk was unsuccessful.
Remedy: Adapt the size of the system logbook (p9930) to the internal RAM disk.
F01023 Software timeout (internal)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: An internal software timeout has occurred.
Fault value (r0949, decimal interpretation):

A01028 Configuration error
Reaction: NONE
Acknowledge: NONE
Cause: The parameterization that was downloaded was generated with a different module type (Order No., MLFB).
Remedy: Save parameters in a non-volatile fashion (p0971 = 1).
F01030 Sign-of-life failure for master control
Reaction: OFF3 (IASC/DCBRAKE, NONE, OFF1, OFF2, STOP2)
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 or, if required, completely disable the monitoring function.
For the commissioning software, the monitoring time is set as follows:
<Drive> -> Commissioning -> Control panel -> Button "Fetch master control" -> A window is displayed to set the
monitoring time in milliseconds.
Notice:
The monitoring time should be set as short as possible. A long monitoring time means a late response when the
communication fails!
