SINUMERIK 840D/840Di/810D Diagnostics Guide (DA) – 11.02 Edition
The cross-check (CRC) has detected an access error in a write/read cycle. All bus
accesses are not controlled directly by the processor but they are handled by special
ASICs. They transfer not only the required data but also cross-checks for the write/read
data and the addresses.
The error can occur in conjunction with a power failure of one or several drive modules. A
hardware fault might also be the cause (ASICs, bus, drive modules).
- NC not ready.
- Mode group not ready, also effective for single axes
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
- Axes of this channel must be re-referenced.
Please inform the authorized personnel/service department. If the alarm has occurred in
conjunction with a power failure, this cause of failure must be eliminated. Otherwise,
please contact the system support for A&D MC products, SIEMENS AG, through the Hot-
line (tel.: see alarm 1000).
Switch control OFF - ON.
Axis %1 drive %2 boot error, error code %3
%1 = NC axis number
%2 = Drive number
%3 = Error code
Error occurred while starting up the displayed drive. (Example: Drive signals timeout).
Meaning of the error code:
• 0..5: Timeout while waiting for the acknowledgement from the drive in the displayed
state
• 10: No signal from drive CPU (possibly defective module)
Safety Integrated special case: If the axial machine data
$MA_SAFE_FUNCTION_ENABLE of at least one axis is not zero, then the occurrence of
this alarm with error code 5 can mean that the PLC, after the timeout
PLC_RUNNINGUP_TIMEOUT, has not started the cyclic operation. Synchronization of
the drive and the PLC is required because in cyclic operation of the drive, data transmis-
sion between the PLC and the drive is monitored.
- Mode group not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. You can try to power the sys-
tem up again. The search for the precise cause of error can only be performed by the
development team. The displayed status code is always needed for this.

1000).
Switch control OFF - ON.
