Axis configuration in tool direction handle feed and normal tool direction
handle feed
[Data type] Byte
[Valid data range] 1 to 4
Let A, B, and C be the rotary axes for the basic three axes X, Y, and Z
in the basic coordinate system in tool direction handle feed and
normal tool direction handle feed. If the tool direction is the Z-axis
when the tool on the rotary axes is at the machine zero point, the four
types below are considered according to the machine axis
configuration. For a 4-axis machine, types (1) and (2) are available.
(1) A-C axis type
(2) B-C axis type
(3) A-B axis (A-axis master) type
(4) A-B axis (B-axis master) type
This parameter selects a type. Values of 1 to 4 are assigned to these
types (when bit 0 (TLX) of parameter No. 7104 is set to 1), in order,
from top to bottom. When the X-axis represents the tool direction, the
above types are changed to B-A axis type, C-A axis type, B-C axis
(B-axis master) type, and B-C axis (C-axis master) type.
7121
Axis selection in tool direction handle feed mode
[Data type] Byte
[Valid data range] 1 to number of controlled axes
This parameter sets an axis number for the manual handle feed axis
selection signal for the first manual pulse generator to enable tool
direction handle feed mode. When the value set in this parameter
matches the value of the manual handle feed axis selection signal, tool
direction handle feed mode is enabled.
7141
Axis selection in the X direction for the normal tool direction handle feed
7142
Axis selection in the Y direction for the normal tool direction handle feed
[Data type] Byte
[Valid data range] 1 to 8
These parameters specify the axis selection signal for the first manual
pulse generator used to enable the normal tool direction handle feed.
When the setting of these parameters matches the manual handle feed
axis selection signal, normal tool direction handle feed mode is
enabled.
