SINUMERIK 840D/840Di/810D Diagnostics Guide (DA) – 11.02 Edition
- Alarm display.
- Interface signals are set.
- Local alarm reaction.
- NC Stop on alarm.
- NC Start disable in this channel.
• Please inform the authorized personnel/service department. If possible, modify the
measuring motion such that the axis concerned does not have to travel; do not program
this axis in the MEAS block again. However, it is then no longer possible to query a
measured value for this axis.
• Ensure that measurement is not taking place with simulated encoders (MD
$MA_ENC_TYPE).
Clear alarm with the RESET key. Restart part program
Axis %1 machine data %2 value changed
%1 = Axis name, spindle number
%2 = String: MD identifier
Machine data contains an invalid value and therefore has been changed by the software.
- Alarm display.
Check MD.
Clear alarm with the RESET key. Restart part program
Axis %1 machine data %2[%3] value changed
%1 = Axis name, spindle number
%2 = String: MD identifier
%3 = Index: MD array index
Machine data contains an invalid value and therefore has been changed by the software
internally to a valid value.
- Alarm display.
Check MD.
Clear alarm with the RESET key. Restart part program
Axis %1 encoder %2 absolute position lost
%1 = Axis name, spindle number
%2 = Encoder number
The absolute position of the absolute encoder has become invalid because
- on changing parameter block a changed gear stage ratio was identified between
encoder and processing or
- the encoder has been replaced (the absolute encoders serial number has changed).
- Mode group not ready.
- Channel not ready.
- If the axis is a single axis when this alarm is triggered, the alarm is only effective for this
axis (not effective for e.g. the channel or mode group)
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
- Axes of this channel must be re-referenced.
