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.
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.
