Machine-data settings
Machine data can be used to define programming and positioning (MD30310
$MA_ROT_IS_MODULO) as well as the position display (MD30320
$MA_DISPLAY_IS_MODULO) individually in modulo 360° for each rotary axis, depending on
the particular machine requirements.
Axis is modulo
MD30310 $MA_ROT_IS_MODULO = 1:
Activation of this machine data allows the special rotary-axis response to be utilized. The
rotary-axis positioning response is thus defined during programming (
G90, AC, ACP, ACN or DC).
A modulo 360° representation is executed within the control after the current zero offsets
have been taken into account. The resulting target position within a revolution is then
approached.
The software limit switches and working-area limitations are inactive, meaning that the
operating range is unlimited (continuously-turning rotary axis).
