4.2.2 Moving Axis and Direction Selection
In MPG mode, press key to select the corresponding axis. The page is as follows (Other axes
are the same):
The handwheel feed direction is defined by its rotation direction. Generally, the handwheel CW is for
positive feed, and CCW is for negative feed. In case of that handwheel CW is for negative feed, CCW for
positive feed, it may exchange the A, B signals of the handwheel terminals,also you can modify the HWX.
HWY. HWZ. HW4. HW5 of the bit parameter
№0175.
4.2.3 Explanation Items
1. The correspondence between the handwheel scale and the machine moving amount is as following
table：
Moving amount of each handwheel scale
Handwheel
increment
0.001 0.0100 0.100 1.000
Specified
coordinate value
0.001mm 0.010mm 0.100mm 1.000mm
2. The rotation speed of the handwheel should be more than 5 r/s, if it is over it, the scale may be not
coincide with the moving amount
3. The handwheel axis selection key is valid only in the MPG mode.
