PROGRAMMING20. AXIS CONTROL FUNCTIONS
B–63534EN/02
532
This function controls a rotary axis as specified by an absolute command.
With this function, the sign of the value specified in the command is
interpreted as the direction of rotation, and the absolute value of the
specified value is interpreted as the coordinates of the target end position.
This function is valid when rotary axis roll–over is enabled (ROAx bit (bit
0 of parameter 1008) is set to 1).
If the RAAx bit (bit 3 of parameter 1008) is set to 1, an absolute command
specified for the roll–over rotary axis is interpreted as follows: The sign
and absolute value of the value specified in the command represent the
direction of rotation and the end position of movement respectively.
If the RAAx bit (bit 3 of parameter 1008) is set to 0, the setting by the
RABx bit (bit 1 of parameter 1008) becomes significant.
NOTE
1 This function can be used only when the corresponding
option is provided.
2 This function is valid for a roll–over rotary axis.
3 If the RAAx bit (bit 3 of parameter 1008) is set to 1, the RABx
bit (bit 1 of parameter 1008) is ignored. To select a rotary
motion of a shorter travel distance, set both RAAx and RABx
to 0.
4 This function is not supported when the machine coordinate
system of the PMC axis control function is selected.
