NC Start inhibited.
NC Stop at alarm.
The NC changes to follow-up mode.
Alarm display.
Interface signals are set.
The axes are no longer synchronized with the machine actual value (reference
point).
Check if the measuring circuit connector is connected correctly. Check en-
coder signals and replace encoder in case of errors.
Power ON
Axis %1 pollution of active encoder
%1 = Axis name, spindle number
The encoder used for position control signals pollution signal (only with meas-
uring systems that provide this option).
Mode group ('BAG') not ready for operation.
Channel not ready for operation.
NC Start inhibited.
NC Stop at alarm.
The NC changes to follow-up mode.
Alarm display.
Interface signals are set.
The axes are no longer synchronized with the machine actual value (reference
point).
Check the measuring system with respect of the settings of the measuring sys-
tem manufacturer.
Press the RESET key to clear the alarm. Restart part program.
Axis %1 zero mark monitoring of active encoder
%1 = Axis name, spindle number
The pulses of the position encoder between 2 zero mark pulses are counted
(hardware function). It is checked whether the encoder always provides the
same number of pulses between the zero marks. As soon as a deviation in the 4
less-significant bits of the counter is ignored, an alarm is output.
Mode group ('BAG') not ready for operation.
Channel not ready for operation.
NC Start inhibited.
NC Stop at alarm.
The NC changes to follow-up mode.
Alarm display.
Interface signals are set.
The axes are no longer synchronized with the machine actual value (reference
point).
The deviations might have been caused by transmission errors, interference,
encoder hardware errors or errors in the evaluation electronics of the encoder
used for position control. Therefore, the following should be checked in the
actual value branch:
