Drive bus hardware fault
Definitions:
The drive bus has a fault. The following causes are possible:
- The bus terminator is missing.
- The drive bus is physically interrupted at some point.
- Miscellaneous hardware fault.
A check line is tested that runs over the entire bus and returns from the last rack location (bus
terminator) back to the NCK.
Note: If the drive ramps up correctly even though this message appeared, the error existed only at the
beginning of the initialization. In spite of this, the drives can be capable of functioning.
Reaction:
Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy:
Please inform the authorized personnel/service department.
- Check the bus terminator.
- Check all plug connections from the drive bus to the drive modules.
- Other hardware faults.
If the remedial measures given above do not lead to a change in the behaviour when starting, please
contact the system support for the A&D MC products of SIEMENS AG through the Hotline (tel.: see
alarm 1000).
