Axis Parameters
Chapter 4
4-13
Function
This parameter is available only when configuring a rotary axis (selected
with the F2 option). Typically, for rotary tables, this value represents full
rotation of the axis (normally 360 degrees).

Rotary Axis Rollover Value (configured to rollover at 360 degrees)
Rollover point
90
180
270
0
Starting at 270 ° and moving 180 ° clockwise
puts the axis in the 90 ° position, not the 450 °
position. The rotary axis position rolls over to
zero at the rollover point.

Notes
Assigning a rollover point of 0 degrees disables the rollover feature. When
rollover is disabled the rotary axis is no longer sign dependant in absolute
mode (programming --90 degrees and +90 degrees will position to the same
location since there is no rollover from which to calculate negative angles).
Each of these parameters must be set independently for each rotary axis.
