- Mode group not ready, also effective for single axes
- NC Start disable in this channel.
- Axes of this channel must be re-referenced.
- Interface signals are set.
- Alarm display.
Remedy: 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).
Program Con- Switch control OFF - ON.
tinuation:
300202
Axis %1 drive %2 CRC error, error location %3
Parameters: %1 = NC axis number
%2 = Drive number
%3 = Error location
Definitions: 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).
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Mode group not ready, also effective for single axes
- NC Start disable in this channel.
- Axes of this channel must be re-referenced.
- Interface signals are set.
- Alarm display.
Remedy: 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).
Program Con- Switch control OFF - ON.
tinuation:

Axis %1 drive %2 boot error, error code %3
Parameters: %1 = NC axis number
%2 = Drive number
%3 = Error code
Definitions: 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.
Reactions: - Mode group not ready.
