Parameter JHD (bit 0 of No. 7100) enables or disables the manual pulse
generator in the JOG mode.
When the parameter JHD( bit 0 of No. 7100) is set 1,both manual handle
feed and incremental feed are enabled.
Parameter THD (bit 1 of No. 7100) enables or disables the manual pulse
generator in the TEACH IN JOG mode.
Parameter HPF (bit 4 of No. 7100) specifies as follows:
SET VALUE 0: The feedrate is clamped at the rapid traverse rate and
generated pulses exceeding the rapid traverse rate are
ignored.(The distance the tool is moved may not match
the graduations on the manual pulse generator.)
SET VALUE 1: The feedrate is clamped at the rapid traverse rate and
generated pulses exceeding the rapid traverse rate are not
ignored but accumulated in the CNC.
(No longer rotating the handle does not immediately stop
the tool. The tool is moved by the pulses accumulated
in the CNC before it stops.)
Parameter HNGX (No. 7102) switches the direction in which the tool
moves along an axis, corresponding to the direction in which the handle
of the manual pulse generator is rotated.
Up to three manual pulse generators can be connected, one for each axis.
The three manual pulse generators can be simultaneously operated.
Handle feed is not effective in T and C axis.
WARNING
1 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.
2 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.
