- Alarm display.
- Interface signals are set.
- NC Stop on alarm.
- Interpreter stop
- NC Start disable in this channel.
Modify part program.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 language change not possible:
%1 = Channel number
%2 = Block number, label
%3 = Cause
The selection of an external NC language is not possible due to the reason specified. The
following reasons are possible (see parameter 3):
1. Invalid machine data settings
2. Active transformation
- Alarm display.
- Interface signals are set.
- Interpreter stop
- NC Start disable in this channel.
Remedy the specified cause of the error before selecting the language.
Clear alarm with the RESET key. Restart part program
Channel %1 axis %2 reference cam not reached
%1 = Channel number
%2 = Axis name, spindle number
After starting the reference point approach, the rising edge of the reduction cam must be
reached within the section defined in the MD 34030 REFP_MAX_CAM_DIST (phase 1 of
referencing). (This error occurs only with incremental encoders).
- NC Stop on alarm.
- NC Start disable in this channel.
- Alarm display.
- Interface signals are set.
- 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)
Please inform the authorized personnel/service department. There are 3 possible causes
of error:
1. The value entered in MD 34030 REFP_MAX_CAM_DIST is too small. Determine the
maximum possible distance from the beginning of reference motion up to the reduction
cam and compare with the value in the MD: REFP_MAX_CAM_DIST, increase the value
in the MD if necessary.
2. The cam signal is not received by the PLC input module. Operate the reference point
switch by hand and check the input signal on the NC/PLC interface (route: switch!connec-
tor!cable! PLC input!user program).
3. The reference point switch is not operated by the cam. Check the vertical distance
between reduction cam and activating switch.
Clear alarm with the RESET key. Restart part program
Channel %1 axis %2 no cam signal present
%1 = Channel number
%2 = Axis name, spindle number
