3. MANUAL OPERATION

Parameter JHD (bit 0 of No. 7100) enables or disables the manual handle
feed 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 handle
feed in the TEACH IN JOG mode.
Parameter HPF (bit 4 of No. 7100) or (No. 7117) specifies as follows:
Parameter HPF (bit 4 of No. 7100)
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 HPF (No. 7117) (It is available when parameter HPF is 0.)
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.)
Other than 0 : 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 until the limit
specified in parameter No. 7117 is reached.
(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 #0) switches the direction of MPG 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.
