1.11 ROTARY AXIS CONTROL
Overview
A rotary axis is specified with bit 3 (RAAx) 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.
To set the roll over function, set the following parameters:
- Parameter ROTx (No.1006#0) = 1 (Rotary axis)
- Parameter ROAx (No.1008#0) = 1 (Rollover is valid.)
- Parameter No.1260 = Travel distance per rotation of a rotation
axis
To set rotary axis control, set the following parameter:
- Parameter RAAx (No.1007#3) = 1 (Rotary axis control)
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.
