Operating modes
6.5.1
DM – Individual distance measurement
The LDM52 OEM will perform exactly one measurement and then wait for new instructions.
The duration of the measurement depends on the number of preset measuring values SA and
the preset measuring frequency MF.
Input:
DM
Typical parameter settings
MF0, SA1, DM
Execute single measurement, allowing for a sufficient period of time as needed to determine the
distance to a static (during the measurement) target object.
MFx, SA1, DM
Execute single measurement, allowing for a period of time of maximally 1 / x seconds to reliably
determine the distance to a static (during the measurement) target object.
6.5.2
DT – Continuous distance measurement (distance tracking)
The LDM52 OEM performs a continuous measurement.
The measurement can be interrupted by a command:
ESC (Escape)
= 0x1B
SDT
= 0x53 0x44 0x54
The output frequency of the measured values depends on the selected parameters MF and SA.
The DT mode works with high measuring stability in the collection of the measured values, even
in case of beam interruptions and discontinuous motion sequences of the target.
Input: DT
Full measurement (new adjustment of frequencies to define the unambiguous range)
will be forced after beam interruptions.
