Rotary axis control
1.1 ROTARY AXIS CONTROL FUNCTION
Overview
A rotary axis is specified with bit 3 (RAA) of parameter No. 1007. When an
incremental command is specified for a rotary axis, the specified value itself
sets a travel distance.
When an absolute command is specified, the direction of rotation is
determined by the sign of the specified value, and a rotation is made to the
position determined by rounding the absolute value of the specified value to
within one rotation.
An absolute coordinate on a rotary axis is displayed after being rounded to
within a travel distance per rotation set by parameter No. 1260.
This function is optional.
Explanation
• Setting
This function is valid for a rotation axis for which the use of rollover is set.
Set the parameters below to use this function.
・Operation
When an absolute command is specified for an axis set as a rotary axis, the
direction of rotation is determined by the sign of the specified value, and the
end point coordinate is determined by the absolute value of the specified
value.
Example) Operation performed when the B-axis is set as a rotary axis
G90 B0; Moves to the 0-degree position.
G90 B380.; Rotates 20 degrees in the positive direction to move to
the 20-degree position.
G90 B-90.; Rotates 290 degrees in the negative direction to move
to the 90-degree position.
G90 B60.; Rotates 330 degrees in the positive direction to move
to the 60-degree position.
When an incremental command is specified, the specified value itself sets a
travel distance.
By setting bit 5 (G90) of parameter No. 1007 to 1, a rotary axis control
command can be regarded as an absolute command at all times.
・ROT (No.1006#0) = 1 (Rotary axis)
・ROA (No.1008#0) = 1 (Rollover is valid.)
・No.1260 = Travel distance per rotation of
a
rotation axis
Rollover setting
・RAA (No.1007#3) = 1 (Rotary axis control)

For short-cut rotation, set both parameters RAA and RAB to 0. ・ This function has no effect for a machine coordin
