5-2 Fail-Safe Measures
The fail-safe measures are the same for each series. Confirm the following instructions.
• If you wish to operate a stage and/or a robot using a measurement result from a FH Sensor
Controller (e.g. axis movement amount output based on calibration/alignment measure
-
ment), always take safety measures before operation so that measurement results are
r
e-checked by the stage/robot if it is within the range of movement of the stage/robot.
Precautions for Correct Use
Fail-Safe Measures
• When controlling stages and robots using the measurement results from the Sensor Control-
ler (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 measurement results is within the range of movement of the stages and
robots.
• On the Sensor Controller side, use logical operation
s and conditional branches in a comple-
mentary way to add a check process based on the range of movement of the stages and
robot
s, for example, "data is not externally output if in a range of -XXXXX to XXXXX."
Communication with High-order Device
After confirming that this product is started up,
communicate with the high-order device. During
start-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.
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 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.
An abnormal operation may result in a serious accident.
