Question
What is the positional variation range with
respect to the machine axis of the emitter
beam spot?
After the response time is changed, is it
necessary to re-execute smart tuning?
If using a different bank for the first time, is it
necessary to execute smart tuning?
For the line beam type, is it possible to detect
beam-spot-internal steps?
Is it possible to add additional extension
cables between the Sensor Head and
Amplifier Unit?
About how much signal input and open time is
required for each input operation?
Can calculations be performed when Sensor
Heads that have different measurement
ranges are connected to two Amplifier Units?
How can I prevent an incorrect value being
measured and output due to the shape of the
workpiece?
Does the sensor need to be warmed up after
canceling LD-OFF input?
Can the sensor head of a diffuse-reflective
model be tilted like that of a regular-reflective
model?

Answer
The range is ±0.5° of the ideal emitter axis in
the dimensional drawing on page 138.
Yes. After the response time is changed, the
smart tuning results are cleared. Therefore,
re-execute tuning.
Yes. The smart tuning results are not applied
to other banks. If using a different bank for the
first time, execute smart tuning.
Spot-internal steps cannot be measured. Use
the line beam spot so that it is at only one
height.
Regardless of the length, only one extension
cable can be added. It is not possible to add
multiple extension cables.
These times can be checked using the timing
charts in this manual (on page 144).
Yes. This is possible without specifying any
special settings.
If the incorrect measurement is caused by
multireflection due to the shape of the
workpiece, setting the detection surface
selection to MAX might improve the
measurement accuracy. (See page 120.)
Yes. The sensor must be warmed up for at
least 10 minutes in the same way as when
turning on the power.
Yes it can, but because the sensor is tilted,
the actual measurement distance between
the sensor and the workpiece will differ from
the distance displayed.
In this case, use a regular-reflective model
whose linearity has been optimized by using
regular-reflective optics.
