The probe must operate virtually bounce-free. Most sensors can be adjusted mechanically to ensure that they operate in this
manner.
Different types of probes supplied by a variety of manufacturers are available on the market. Probes are therefore divided
into three groups according to the number of directions in which they can be deflected (see figure below).
For probe assignment, see the table below:
Milling and machining centers
Bi-directional X
A mono-probe can also be used for this purpose for milling and machining centers.
Multidirectional probe (3D)
This probe type can be used unconditionally for measuring tool and workpiece dimensions.
This probe type is handled in the same way as a mono probe in milling and machining centers.
This probe type can be used, with only a few restrictions, to take workpiece measurements on milling and machining centers.
The spindle must be capable of being positioned with the
NC function if the measurement is to be carried out in
different axis directions/axes. The probe must therefore be aligned according to the measuring task.
The signal level of the connected probe (deflected/non-deflected condition) must be communicated to the control via the
MD13200 MEAS_PROBE_LOW_ACTIVE[0].
The probe for the control system is connected to pin4 (DI1) and pin5 (DI2) of X21. The actually used pin is determined by
the relevant macro command. Thus, all measuring inputs of the axis drive modules are operated whose axes are involved in
measuring. For the probe, use an external voltage (24 V) whose reference potential should be connected to X21, pin 10.
To ensure optimum interference immunity when connecting probes, lines must be used.
