# Number of probing input (P-AXIS-00517)

P-AXIS-00517 | Number of probing input
Description | The parameter defines the measuring channel which is used during a measurement travel. When the DRIVE measurement method is set (see P-AXIS-00516), it must also be parameterised in the drive (see [FCT-C4]). The parameter replaces the setting antr.probing_input_nbr (P-AXIS-00430).
Parameter | kenngr.measure.input
Data type | UNS08
Data range | Valid probing inputs dependent on drive type and probing signal source (see table below):
Measurement methods P-AXIS-00516 | Drive type P-AXIS-00020 | Probing inputs
PLC_EXT_LATCH_CONTROL | all | 1 to 255
EXT_PROBE_WITH_DRIVE | all | 1 to 2
DRIVE | SERCOS CANopen PROFIDRIVE MC | 1 to 2
Conventional Beckhoff Lightbus +-10V via Feldbus Real-time (RT)-Ethernet CAN-Bus | 1
Axis types | T, R, S
Dimension | T: ---- | R,S: ----
Default value | 0 **
Drive types | ----
Remarks | *All probing signals which are not listed in the table above do not use the parameter 'Input' for the probing input. **If the parameter P-AXIS-00517 is not specified, the setting in P-AXIS-00430is used for reasons of backward compatibility.
