3.2 MANUAL HANDLE FEED
General
In the manual handle feed mode, the tool can be minutely 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. 1414
and 1418).
The handle magnifications can be selected by the manual handle feed
move distance selection signal.
Up to three manual pulse generators can be connected.
- A command to the MPG exceeding rapid traverse rate
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.)

[Classification] Input signal
[Function] Selects the axis of manual handle feed. A set of four code signals, A, B,
C, and D is provided for each manual pulse generator. (Up to three
generators can be used.) (For two-path, these signals are provided for
each manual pulse generator and each path.) The number in the signal
name indicates the number of the manual pulse generator to be used.

x : 1 ..... First manual pulse generator
2 ..... Second manual pulse generator
3 ..... Third manual pulse generator (M series)
Code signals A, B, C, and D correspond to the feed axes as listed in the
following table:
