5-2 Fail-Safe Measures

The fail-safe measures are the same for each series. Confirm the following instructions.

Precautions for Safe Use

• 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

re-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 operations and conditional branches in a comple-

mentary way to add a check process based on the range of movement of the stages and

robots, 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.
