Switching performance
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].
13.2.2
Probe connection
The probe for SINUMERIK 802D sl is connected to the terminals of X20. The particular
assignment is determined by the macro you are using. 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 must be connected to X20, pin 12.
To ensure optimum interference immunity when connecting probes, shielded lines must be
used.

Channel-specific measuring
13.3.1
Measuring mode
Measuring commands MEAS and MEAW
The measuring operation is activated from the part program. A trigger event and a
measuring mode are programmed. Two different measuring modes are available:
●
MEAS: Measurement with deletion of distance-to-go
Example:
N10 G1 F300 X300 Z200 MEAS=-1
Trigger event is the falling edge (-) of probe 1: from deflected to non-deflected status.
●
MEAW: Measurement without deletion of distance-to-go
Example:
N20 G1 F300 X300 Y100 MEAW=1
Trigger event is the rising edge of probe 1: from non-deflected to deflected status.
The measurement block is terminated when the probe signal has arrived or the programmed
position has been reached. The measurement job can be cancelled with RESET.
