Input Filter Time Constant (Pr. 74) - Mitsubishi Electric FR-E700 Series Instruction Manual

Frequency setting by analog input (terminal 2, 4)
6.16.2

Input filter time constant (Pr. 74)

If the set point signal (terminal 2 or 4) is an unstable signal or contains noise you can filter out the in-
stability or noise by increasing the setting value of Pr. 74.
Pr. No. Name
74
Input filter time constant
The above parameters can be set when Pr. 160 "User group read selection" = 0.
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 5ms to 1s with the
setting of 0 to 8.)

Setting
Initial Value Description
Range

1 0–8 log input.
A larger setting results in a larger filter.
