Probing from OEM

With FN17:SYSWRITE ID990 NR1, adjust the approach behavior. If the input

value = 0, the setup clearance from MP6140 and the effective radius are

accounted for. If the input value > 0, the workpiece is approached as if the

effective radius and setup clearance were zero. This function can be used,

for example, for measuring small holes.

If you use the TS 632 infrared touch probe, you must orient the touch probe

before the measuring process in order to align the touch probe and the

receiver unit. Define an M function for automatically orienting the probe to a

specific position before probing. If the ready signal of the touch probe is

already available, the touch probe is not oriented.

In MP6161, enter the number of the M function.

Enter the orientation angle in MP6162.

In MP6163, enter a minimum angle difference for orienting with the defined
