Axis %1 drive %2 CRC error, error location %3
%1 = NC axis number %2 = Drive number %3 = Error location
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.
- 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.
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 Hotline (tel.: see alarm 1000).
Switch control OFF - ON.
