Explanation:
For G335/G336 (thread cutting with a convex thread) the pitch parameter could not be assigned to a velocity-defining axis.
The error number specifies the precise cause:
Error 1 : The pitch parameter does not match the end points or the program circular plane.
Error 2 : A circular path angle of greater than 90 degrees was programmed.
Error 3 : The circular path has a helical component (helix).
Error 4 : The circular path exceeds one of the angles 45/135/225/315 degrees in the programming.
Error 5 : The circular path exceeds one of the angles 45/135/225/315 degrees after calculating in the frame.
Error 6 : The pitch was not programmed for the axis with the longest traversing path.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
- check circle programming or
- assign pitch parameter to the axis with the longest traversing distance.

[Channel %1: ] Block %2 no geometry axis programmed
Parameters:
%1 = Channel number
%2 = Block number, label
Explanation:
No geometry axis was programmed for tapping (G33) or for rigid tapping (G331, G332). The geometry axis is, however,
essential if an interpolation parameter has been specified.
Example:
N100 G33 Z400 K2 ; thread pitch 2mm, thread end Z=400 mm
N200 SPOS=0 ; position spindle in axis mode
N201 G90 G331 Z-50 K-2 ; tapping to Z=-50, counterclockwise
N202 G332 Z5 ; retraction, direction reversal automatic
N203 S500 M03 ; spindle again in spindle mode
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Specify geometry axis and corresponding interpolation parameters.
Programm
continuation:
Clear alarm with NC START or RESET key and continue the program.

[Channel %1: ] Block %2 spindle %3 selected gear stage %4 not installed
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Spindle number
%4 = Gear stage
Explanation:
The first gear stage data block is active. The required gear stage is not installed in the 1st gear stage data block. The
number of gear stages installed is configured in MD35090 $MA_NUM_GEAR_STEPS.
Examples of the occurrence of the alarm with 3 three gear stages installed (MD 35090 $MA_NUM_GEAR_STEPS = 3):
* ... M44 or M45 has been programmed for the spindle concerned
*...M70 has been programmed and MD35014 $MA_GEAR_STEP_USED_IN_AXISMODE is larger than 3.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Modify part program: Only those valid gear stages can be entered which have also been installed according to MD35090
$MA_NUM_GEAR_STEPS.
Limit M70 configuration (MD 35014 $MA_GEAR_STEP_USED_IN_AXISMODE) to MD35090 $MA_NUM_GEAR_STEPS.
Programm
continuation:
Clear alarm with NC START or RESET key and continue the program.
