14.27.8.4 Tool Center Point Rotation Output

Con-
Signal name
tact
A In tool center point rotation
[Function]
This signal informs the operation of the rotation axis of 3-dimensional manual feed (JOG/incremental/handle).
[Operation]
This signal informs that it operates with keeping the positional relationship of tool center point looking from the workpiece,
when the rotation axis of 3-dimensional manual feed (JOG/incremental/handle) is operated.

14.27.9 Precautions

(1) Speed clamp
Apply a speed limit so that the rapid traverse rate or cutting feed clamp speed is not exceeded by the speed calculated by
distributing the travel amount in the hypothetical coordinate system among each machine axis direction.
Clamp the rotary axis feedrate so that the manual feedrate of a linear axis does not exceed the linear axis feedrate of
"Rotation with the tool tip as the center" with the JOG/incremental feed. When using the handle feed, clamp the rotary axis
feedrate so that the linear axis feedrate does not exceed the rapid traverse rate (#2001 rapid) or cutting feed clamp speed
(#2002 clamp).
(2) Acceleration, Deceleration and time constant
Set the same cutting feed acceleration/deceleration type and same time constant for all the axes involved in the 3-
dimensional manual feed (They have to be the same, because the interpolation is made using the travel amounts distributed
to each axis).
(3) Feed amount
The incremental feed amount and handle feed amount by one pulse are expressed with the feed amount in the composite
direction of the selected coordinate system. When Initial inch is selected, the increment is in one inch unit.
(4) Restart after alarm restoration
When the operation error "M01 Multi ax for 5-ax manual feed 0230" or "M01 5-ax manual feed coord sys err 0231" occurs
during axis movement, the moving axis decelerates and stops. The axis does not restart movement even after the alarm has
been cancelled.
If you want to resume the axis movement, give the command to the axis again.
(5) Magnification
The available range of the incremental feed magnification is between 1 and 100000.
The magnification for handle feed is between 1 and 1000. If a speed is clamped, the number of pulses and the axis' travel
amount do not match. In this case, however, the counter display and the machine position value are matched.
(6) Machine lock
For an axis to which the manual machine lock signal is ON, the [Machine position] counter is locked. If a travel command is
given to the manual machine lock axis, axis travel is made by the travel amounts distributed to each axis, but the manual
machine lock axis itself does not move.
