12.4 Activating rotary axes
Procedure
The procedure for activating rotary axes is the same as that for linear axes with a small
number of exceptions. It should be noted that, as soon as the axis is defined as a rotary axis
(MD30300 $MA_IS_ROT_AX = 1), the axis-specific-machine-/setting-data units are
interpreted by the control as follows:
Positions In "degrees"
Velocities In "rev/min"
Accelerations In "rev/sec
2
"
Jerk limitation In "rev/sec
3
"
Special machine data
Special rotary-axis machine data may also have to be entered, depending on the application:
MD30310 $MA_ROT_IS_MODULO Modulo conversion for positioning and
programming
MD30320 $MA_DISPLAY_IS_MODULO Modulo conversion for position display
MD10210 $MN_INT_INCR_PER_DEG Computational resolution for angular positions
The following overview lists the possible combinations of these machine data for a rotary
axis:

Comment
0 0 0 Yes The axis is a linear axis (default).
1 0 0 Yes The axis is a rotary axis; modulo
conversion is not used for positioning, i.e.
the software limit switches are active; the
position display is absolute.
1 0 1 Yes The axis is a rotary axis; modulo
conversion is not used for positioning, i.e.
the software limit switches are active; the
position display is modulo;
Application: for axes with an operating
range of +/-1000°, for example
