Function
The preactivation of protection areas with specification of a position offset is programmed in the part program. The preactivated protection areas can be made operative in the PLC user program via the PLC interface. As a result, the relevant protection area is activated, for example, before a tool probe is swiveled into position in the working area, to see whether the tool or a workpiece is in the path of the swiveling part.
The PLC can put another axis limitation into effect by activating the 2nd software limit switch via a PLC interface signal. This reduction of the working area may become necessary, for example, when a tailstock is swiveled into position. The change is immediately effective and the 1st software limit switch +/- is no longer valid.
