Activating the contour handwheel in "AUTO" mode
Activating the contour handwheel in "MDA" mode
Tra versing direction of axes
The axis traversing direction depends on the rotation direction of the contour handwheel:
● Clockwise → results in traversing in the programmed direction
If the block-change criterion is reached, the program advances to the next block (response identical to G60).

1. Open the desired NC program in the part program editor window. For more information
about how to create or edit a part program, see Chapter "Creating part programs
(Page 29)".
2. Enter the mandatory instructions "G1" (or "G2"/"G3"), "G94", "G60" and "FD=0" in the
blocks. The blocks are saved automatically. See the following example:
N o te:
"FD" and "F" cannot appear in the same NC block; otherwise, the control system
•
prompts an alarm which interrupts the contour handwheel function.
When the block runs to "FD=0", you can control the feedrate of path and synchronized
•
axes via a handwheel in "AUTO" mode.
3. Press this softkey to execute the program. The system automatically switches to "AUTO"
mode in the machining area.
1. Select the desired operating area.
2. Switch to "MDA" mode.
3. Enter the mandatory instructions "G1" (or "G2"/"G3"), "G94", "G60" and "FD=0" in the
blocks. The blocks are saved automatically. See the following example:
You can alternatively load an existing part program from a system directory by pressing this
softkey if desired and enter "FD=0", "G94" and "G60" in the blocks.
N o te:
"FD" and "F" cannot appear in the same NC block; otherwise, the control system prompts
an alarm which interrupts the contour handwheel function.
4. Press this key on the MCP. When the block runs to "FD=0", you can control the feedrate of
path and synchronized axes via a handwheel in "MDA" mode.
