Reaction:
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.
Remedy:
Please inform the authorized personnel/service department. Rereferencing/resynchronization of the absolute encoder;
attach absolute encoder on the load side and configure correctly (e.g. MD 31040 $MA_ENC_IS_DIRECT).
Programm
continuation:
Restart part program. Clear alarm with the RESET key in all channels of this mode group. Restart part program.
26040
Axis %1 encoder parameterization MD %2[%3] has been adjusted.
Parameters:
%1 = Axis number
%2 = MD identifier
%3 = Machine data index
Explanation:
The parameterization of the encoder in P979 read out from the drive and displayed in the MD does not match the NCK
parameterization. The corresponding NCK-MD has been adapted.
Reaction:
NC not ready.
The NC switches to follow-up mode.
Mode group not ready, also effective for single axes.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Power on required. This alarm only occurs when the NC-MD is set unequal to the drive parameter.
Programm
continuation:
Switch control OFF - ON.
26050
Axis %1 parameter set change from %2 to %3 not possible
Parameters:
%1 = Axis name, spindle number
%2 = Index: current parameter block
%3 = Index: new parameter block
Explanation:
The parameter block change cannot be performed without jumps. This is due to the content of the parameter block to be
switched on, e.g. different load gear factors.
Reaction:
The NC switches to follow-up mode.
Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
In the following cases, the parameter block change is carried out via MD31060 $MA_DRIVE_AX_RATIO_NUMERA and
MD31050 $MA_DRIVE_AX_RATIO_DENOM without an alarm, even with different load gear ratio settings:
1. If no position control is active (e.g. in follow-up mode or if spindle is in speed-controlled mode).
2. For position control with the direct encoder.
3. For position control with the indirect encoder (the calculated load position difference must not exceed the value indicated
in MD36500 $MA_ENC_CHANGE_TOL).
Programm
continuation:
Clear alarm with the RESET key. Restart part program
