About the Probes
Probes are an option. This machine contains a
Length Probe
and an
Edge Lock Probe (Option).
This machine may be equipped with quadrature encoders.
Quadrature encoders provide high speed bi-directional informa-
tion. Incremental encoders can provide a once-per-revolution
pulse (often called index, marker, or reference) that occurs at the
same mechanical point of encoder shaft revolution. This refer-
ence is used as a comparative point resulting in a highly accurate
measurement. The
encoder assembly
is identified as a
probe
.
Important:
If calibrating, calibrate the probes first.
See Chapter 3 in this manual.

About the Probe Assemblies
The probe assemblies use encoders to get accurate measurements of the door. The measurement
results are fed back to the KvalCAM software.
Edge Lock Probe (Option):
The feeler extends to touch the edge of the
door to calculate the width of the door.
Door Length Probe:
The feeler extends to touch the edge of the
door to calculate the length of the door.
