Adjusting the O2-L Terminal
* Below is the ratio from -10 to 10 V.
-10 to 0 V: -100% to 0%
0 to 10 V: 0% to 100%
• For example, to input voltage ranging from -5 to 5 V on the
O2-L terminal, set A113 to -50%, and A114 to 50%.
O, O2, OI Sampling
•You can set the built-in filter applied to frequency setting signals of the external voltage/current
input.
•Helps remove noise in the frequency setting circuit.
•Set a larger data value if stable operation cannot be secured because of noise.
Note that the larger the data value is, the slower the response time. This parameter specifies a filter
time constant for a set value of 1 to 30 (× 2 ms).
•When "31." is selected, a filter time constant of 500 ms and a hysteresis of ±0.1 Hz are set. (Factory
