ROAx
NOTE
When this parameter is set, the power must be turned off
before operation is continued.
[Data type] Bit axis
ROAx The roll–over function of a rotation axis is
0 : Invalid
1 : Valid
NOTE
ROAx specifies the function only for a rotation axis (for which
ROTx, #0 of parameter No.1006, is set to 1)
RABx In the absolute commands, the axis rotates in the direction
0 : In which the distance to the target is shorter.
1 : Specified by the sign of command value.
NOTE
RABx is valid only when ROAx is 1.
RRLx Relative coordinates are
0 : Not rounded by the amount of the shift per one rotation
1 : Rounded by the amount of the shift per one rotation
NOTE
1 RRLx is valid only when ROAx is 1.
2 Assign the amount of the shift per one rotation in parameter
No.1260.
1010 Number of CNC–controlled axes
NOTE
When this parameter is set, the power must be turned off
before operation is continued.
[Data type] Byte
[Valid data range] 1, 2, 3, ..., the number of controlled axes
Set the maximum number of axes that can be controlled by the CNC.
[Example]
Suppose that the first axis is the X axis, and the second and subsequent axes
are the Y, Z, and A axes in that order, and that they are controlled as follows:
X, Y, and Z axes: Controlled by the CNC
A axis: Controlled by the PMC
Then set this parameter to 3 (total 3: X, Y, and Z)
With this setting, the fifth axis (A axis) is controlled only by the PMC, and
therefore cannot be controlled directly by the CNC.
