Precautions for Correct Use
Communication with High-order Device
• After confirming that this product is started up, communicate with the high-order device. When this
product has started up, an indefinite signal may be output from the high-order interface. To avoid this
problem, clear the receiving buffer of your device at initial operations.
Fail-Safe Measures
• When controlling stages and robots using the measurement results from the Sensor Controller (axis
movement output based on calibration and alignment measurement), always take fail-safe measures
within the stage and robot systems, such as checking whether the data obtained from the measure-
ment results is within the range of movement of the stages and robots.
• On a FH Sensor Controller side, supplementary use operations and branches of the Sensor Control-
ler to configure a check flow such as "data should not be externally provide if the data is in a range
from -XXXXX to XXXXX" based on the stage/robots range of movement.
Connecting the Sensor Controller and Monitor with a Switcher and
Splitter (FH/FZ5 series)
• Do not use devices that make the Sensor Controller recognize the monitor again when switching
operation is performed. Re-recognition process in switching operation has an effect such as a delay
in measurement time.
Beam (FHV series)
• The beam center may vary product by product. When mounting this module, be sure to confirm the
center position of the video on the monitor.
The beam center of this product may vary over a couple of pixels due to the variation of ambient tem-
perature because of the material characteristics.
• Select the model by confirming the field of view and camera installation distance on the optical dia-
gram. In addition, the field of view may vary product by product.
When mounting this product, be sure to confirm video using the monitor.
Image Sensor (FHV series)
• For this product, a line may appear depending on the measurement condition or sensitivity because
of the specification of the image sensor.
However, this is not a fault or failure of the product. In addition, although there may be multiple defec-
tive pixels, this is not a fault or failure of the product. Use the product as confirming the actual image.
Communications with Upper Equipment (FHV series)
• Implement communications with upper equipment after confirming that this product has been started
up. In addition, when this product is being started up, unstable signals may be issued by the upper
interface. In the initial operation, take action such as clearing the receiving buffer of the equipment
used.
