Axis %1 pollution of measuring system
%1 = Axis name, spindle number
The encoder used for position control sends a contamination signal (only in measuring
systems with contamination signal).
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- Mode group not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Axes of this channel must be re-referenced.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Please inform the authorized personnel/service department. Check the measuring system
in accordance with the instructions given by the measuring device manufacturer.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 pollution of passive encoder
%1 = Axis name, spindle number
The encoder not used for position control sends a contamination signal (only in measuring
systems with contamination signal).
- Alarm display.
Please inform the authorized personnel/service department. Check the measuring system
in accordance with the instructions given by the measuring device manufacturer.
Clear alarm with the Delete key or NC START.
Axis %1 zero mark monitoring of active encoder
%1 = Axis name, spindle number
The position encoder pulses between 2 zero marker pulses are counted (hardware func-
tion). A check is made in the interpolation cycle grid (standard setting 4 ms) as to whether
the encoder always issues the same number of pulses between the zero markers. As
soon as a difference is registered in the 4 counter bits of lowest significance, an alarm is
triggered!
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- Mode group not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Axes of this channel must be re-referenced.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Please inform the authorized personnel/service department. The differences can result
from transmission errors, disturbances, encoder hardware faults or from the evaluation
electronics in the encoder used for position control. The actual value branch must there-
fore be checked:
