Input filter time constant (Pr. 74)

4.2.29 Input filter time constant (Pr. 74)
Pr. 74 "filter time constant"
You can set the input section's internal filter constant for an external voltage or current
frequency setting signal.
y Effective for eliminating noise in the frequency setting circuit.
y Increase the filter time constant if steady operation cannot be performed due to
noise. A larger setting results in slower response. (The time constant can be set
between approximately 1ms to 1s with the setting of 0 to 8. A larger setting results in
a larger filter time constant.)
