B-63324EN-1/03 OPERATION 3.MANUAL OPERATION
- 69 -
Explanation
- When a manual handle feed faster than the rapid traverse rate is specified
When a handle feed faster than the rapid traverse rate is specified, the
command pulses up to the permissible flow amount set in parameter No.
1413 are accumulated in the CNC.
- Distance the tool is moved by manual handle feed
The minimum distance the tool is moved when the manual pulse
generator is rotated by one gradation is equal to the least input
increment. The magnification for the distance the tool is to be moved
can be selected from 10 times and the two magnifications specified by
parameter Nos. 1414 and 1418.
Restrictions
- Number of MPGs
Up to three manual pulse generators can be connected, one for each
axis. The three manual pulse generators can be simultaneously
operated.
WARNING
Rotating the handle quickly with a large magnification
such as x100 moves the tool too fast. The feedrate is
clamped at the rapid traverse feedrate.
NOTE
Rotate the manual pulse generator at a rate of five
rotations per second or lower. If the manual pulse
generator is rotated at a rate higher than five
rotations per second, the tool may not stop
immediately after the handle is no longer rotated or
the distance the tool moves may not match the
graduations on the manual pulse generator.
