Checking and setting B and C axes
B337EN05.DOC
The C axis is corrected by the software in the machine data. The
position of the C axis is not changed mechanically.
1. Select >Operation >Set-up >MDA.
2. Enter C0.
3. Press Start.
The C axis travels to 0.
4. Move the X axis slowly in jog mode, enabling the pointer of
the dial gauge to scan the reference area. Read the display on
the dial gauge.
5. Adjust the position of the C axis in jog mode until the deviation
is less than 0.02 mm.
6. Read off the position of the C axis on the actual value display
on the user interface and make a note of this (e.g. +1.3°).
7. Select >Operation >Maintenance/Start-up >Machine data/ axis
specific.
8. Retrieve the machine parameter
MA_REFP_MOVE_DIST_CORR[0] (Index: 34090).
9. Select C axis.
10. Calculate the reference offset value:
–
If the actual value display for the C axis is in the positive
range, add the actual value to the application parameter.
–
If the actual value display for the C axis is in the negative
range, subtract the actual value from the application
parameter.

11. Enter the calculated reference offset value in the machine
parameter.
The newly entered reference offset value for the C axis is now
stored in the PCU 50, but not yet in the NCU.
The new reference offset value must be loaded into the NCU
before carrying out any further checking or setting work.
1. Press ENTER.
2. Press NC core database.
3. Press RESET.
The reference offset value is transferred to the NCU.
4. Repeat the measurement, check the position of the C axis and
readjust it if necessary.
