3. MANUAL OPERATION
168
In manual handle feed mode, the tool can be incrementally moved by
rotating the manual pulse generator. Select the axis along which the tool
is to be moved with the handle feed axis selection signal.
The minimum distance the tool is moved when the manual pulse
generator is rotated by one graduation is equal to the least input increment.
Or the distance the tool is moved when the manual pulse generator is
rotated by one graduation can be magnified by 10 times or by one of the
two magnifications specified by parameters (No. 7113 and 7114).
The handle magnifications can be selected by the manual handle feed
move distance selection signal.
The number of manual pulse generators is as follows.
(M series)
– Up to three generators
(T series)
– Up to two generators
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 generator in the TEACH IN JOG mode.
Parameter (No. 7117) 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.)
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.
(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 in which the tool
moves along an axis, corresponding to the direction in which the handle
of the manual pulse generator is rotated.
