Analog Input Filter (Fv, Fi Sampling) - Omron 3G3MX2 User Manual

If an analog input is used for the frequency reference, current/voltage switch is performed as
follows.

Analog Input Filter (FV, FI Sampling)

Helps remove noise in the frequency setting circuit.
If the frequency reference is specified using an external analog signal, a sampling time can be
set for voltage input or current input.
Set a larger data value if stable operation cannot be secured because of noise.
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 data "31" is selected, a filter time parameter of 500 ms and a hysteresis of ±0.1 Hz are
set.
Parameter
