Fail-Safe Measures
The fail-safe measures are the same for each series. Confirm the following instructions.
WARNING
Please take external safety measures so that the system as a whole should be on the safe
side even if a failure of a Sensor Controller
, a failure of a 3D Vision Sensor, or an error due
to an external factor occurred. An abnormal operation may result in serious accident.
Please take fail-safe measures on your side in preparation for an abnormal signal due to sig-
nal conductor disconnection and/or momentary power interruption.
Precautions for Safe Use
• Be sure to take fail-safe measures externally when controlling stages and robots by using the
measurement results of the Sensor Controller (axis movement output by calibration and
alignment measurement).
Precautions for Correct Use
Fail-Safe Measures
•
Be sure to take fail-safe measures externally when controlling stages and robots by using the
measurement results of the Sensor Controller (axis movement output by calibration and
alignment measurement).
• On a Sensor Controller side, supplementary use operations and branches of the Sensor Con-
troller 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.
Communication with High-order Device
• After confirming that the product is started up, communicate with the high-order device. Since
uncertain signals may be output from the high-order interface at the product start-up, take
measures such as clearing the reception buffer of your device at the initial stage.
