2.1.2 Control with the manual handle (manual pulse generator)
The value of the parameter No.6410 and the scale factors decide the moving amount of the
machine by one pulse generated by a manual handle.
When a manual handle is turned, the actual movement amount of the machine is as follows.
[Feedrate command value] × [Number of the handle pulse per a second]
× [Handle magnification] × ([Parameter setting value]/100) × (8/1000)
When the feedrate exceeds the override 100% feedrate by turning a manual handle rapidly,
the feedrate is clamped at the speed of override 100%. That is, if the pulse of the following
formula exceeds “1”, the feedrate is clamped.
[Number of the handle pulse per a second]
× [Handle magnification] × ([Parameter setting value]/100) × (8/1000)
The rapid traverse feedrate is clamped at 10%. However, the feedrate of the rapid traverse is
clamped at 100% when the parameter No.6400#0 HDRPD is set to “1”.
The single block signal and the feed hold signal are effective in the checking mode. When the
execution of a program is stopped by the single block stop or the feed hold stop, it is
necessary to turn ST signal from “1” to “0” in order to restart the program.
The block with the movement and the block of dwell can control the execution speed of the
program by turning a manual handle. As for the block of neither movement nor dwell such as
the block of only address M, S, T, and F, the program advances to the following block even if a
manual handle does not turn.
The rotation of the spindle does not synchronize with a pulse of a manual handle. During the
checking mode, the spindle rotates at the specified rotation speed. As for the feed per
revolution, a program is executed at the feedrate which was changed from the rotation speed
of the spindle to the considerable feed per minute inside CNC.
Note
The manual handle used by this function is always the first. The 2nd and 3rd manual handle
cannot be used in this function.
