Input Terminal Filter

Filter constant of control circuit terminals (No.2 to No.8) can be set in the
inverter to effectively remove interference of external signal input.
Setting value (times)
・If the setting value is too high, the interference resistance capability will be
enhanced, but response speed of control input terminals will decrease.
・If the setting value is too low, the interference resistance capability will be
weakened, but response speed of control input terminals will increase.
・When start/stop, forward run and reverse run signal (terminal No.2 and No.3)
are used to operate the inverter, internal processing time of the inverter will
become longer even if the setting value is low. In this case, response speed of
control input terminals will be slower than other terminals.
