User's Manual
The range of cut-off frequency to be effective in operation varies depending on the setting of measurement
cycle.
The relationship between the measurement cycle and the cut-off frequency range is shown in the table below.
• If a value outside of the appropriate range is set, the frequency filter will be applied with the values included in the
range.
• If the cut-off frequency values (upper/lower limits) are too close, the frequency bandwidth to be detected cannot be
properly detected.
• If changing the extension fiber cable length setting causes the setting value of the cutoff frequency to fall outside the
upper/lower limit value, the setting value is automatically changed to the value within the limit.
Frequency filter is applicable the measurement result executed TRIG input/Sync0 signal even if select the External/
PDO synchronous measurement mode. In this case, the sampling interval of measured result is used the
measurement cycle value which has been set and executed external TRIG input/Sync0 signal.
The value is not dependent on the interval which is actually executed TRIG input/Sync0 signal.

The frequency filter can also be set by the operating keys on the Sensor Controller.
