- 410 -
7 When feed in the tool axis direction or the direction perpendicular
to the tool axis or rotation around the tool tip center is not selected
for the manual operation or the manual interruption using the
manual pulse generator when the ALNGH, RGHTH, and RNDH
input signals are all “0”.
8 While the playback function is not being executed
The result of adding the feedrate in the three-dimensional coordinate
conversion mode is not permitted to exceed the maximum cutting speed
for each axis.
- Manual interruption and the coordinate system
When this function is effective, the current position in the workpiece
coordinate system does not depend on the travel distance specified
during manual interruption using the manual pulse generator. The
current position is therefore not updated even when the manual pulse
generator is rotated. Each current position in the machine coordinate
system and in the relative coordinate system depends on the travel
distance specified during manual interruption. As shown in Fig. 3.6(a),
the travel distance is added along the Z'-axis. The travel distance is
displayed using the X, Y, and Z coordinates of the coordinate system to
be converted. The travel distance specified by this function can be
monitored on the manual overlap screen. The bit 0 (DMK( bit of
parameter 2208 specifies whether the travel distance is displayed on
the manual overlap screen using the coordinate system before (X, Y,
Z)or after (X’, Y’, Z’) three-dimensional coordinate conversion.
Signal
Three-dimensional coordinate conversion manual interrupt enable/disable switch signal
NOT3DM<G157#7>
[Classification] Input signal
[Function] Enables or disables the three-dimensional coordinate conversion
manual interrupt function.
[Operation] When this signal is set to 0, the three-dimensional coordinate
conversion manual interrupt function is enabled. When this signal is
set to 1, the three-dimensional coordinate conversion manual interrupt
function is disabled.
Three-dimensional coordinate conversion manual interrupt mode in-progress signal
3DMI<F157#5>
[Classification] Output signal
[Function] Posts notification of the three-dimensional coordinate conversion
manual interrupt state.
[Output condition] This signal is set to 1 when all of the following conditions are satisfied:
1. Simultaneous automatic and manual operation mode
(including handle interrupt) is set.
2. Three-dimensional coordinate conversion mode (that is,
from execution of a G68 block to execution of a G69 block)
is set.
