- Interface signals are set.
- Alarm display.
Wait until the axis is stationary.
Clear alarm with the Delete key or NC START.
Channel %1 axis %2 PRESET: illegal value
%1 = Channel number
%2 = Axis name, spindle number
The entered Preset value is too large (number format overflow).
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Use more realistic (smaller) Preset values.
Clear alarm with the RESET key. Restart part program
Axis %1 hardware fault of active encoder
%1 = Axis name, spindle number
The signals of the currently active position actual value encoder (interface signal DB 31 -
48, DBX 1.5 = 1 or DBX 1.6 = 1) are missing, do not have the same phase, or exhibit
grounding/short-circuit.
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 measuring circuit con-
nectors for correct contacting. Check encoder signals and replace the encoder if faults are
found.
Switch control OFF - ON.
Axis %1 hardware fault of passive encoder
%1 = Axis name, spindle number
The signals from the position actual value encoder that is presently not active are missing,
or they are not of the same phase, or they exhibit grounding/short-circuit.
- Alarm display.
Please inform the authorized personnel/service department. Check measuring circuit con-
nectors for correct contacting. Check encoder signals and replace the encoder if faults are
found. Switch off the monitoring with the corresponding interface signal (DB 31 - 48, DBX
1.5 = 0 or DBX 1.6 = 0). o
Clear alarm with the RESET key. Restart part program
