Drive bus hardware fault
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.
- Mode group not ready.
- Channel not ready.
- 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.
- 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).
Switch control OFF - ON.
Axis %1 drive %2 timeout during access, error location %3
%1 = NC axis number
%2 = Drive number
%3 = Error location
The read cycle of a drive address in the initialization phase or in cyclic operation has not
ended within the monitoring time (approx. 1 ms) (timeout error).
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.
