Axis designation for axis IV
90
The axis designation for axis I\/ is determined with parameter 90. The selection of designation A, B or C
determines whether the axis is to be used for control or display of a rotary axis. In this case, the axis is
relieved of mm/inch switchover and can operate with another in linear interpolation without tool radius
compensation. If U, V or W are selected, the axis is then programmed as an additional linear axis, it can also be
used with mm/inch and can operate with one of the other axes in linear or circular interpolation with tool
radius compensation.
