Settings -500.0~500.0%
Parameters 03-03 to 03-14 are used when the source of frequency command is the analog
voltage/current signal.
Analog Input Filter Time (AVI)
Analog Input Filter Time (ACI)
Analog Input Filter Time (AUI)
Settings 0.00~2.00 sec
These input delays can be used to filter noisy analog signal.
When the setting of the time constant is too large, the control will be stable but the control response
will be slow. When the setting of time constant is too small, the control response will be faster but
the control may be unstable. To find the optimal setting, please adjust the setting according to the
control stable or response status.
Addition Function of the Analog Input
Settings 0: Disable (AVI, ACI, AUI)
When Pr.03-18 is set to 0 and the analog input setting is the same, the priority for AVI, ACI and AUI
are AVI>ACI>AUI.
Frequ ency
Treatment to 4-20mA Analog Input Signal Loss
Settings 0: Disable
This parameter determines the behavior when 4~20mA signal is loss, when AVI(Pr.03-28=2) or ACI
(03-29=0).
When Pr.03-28 is not set to 2, it means the voltage input to AVI terminal is 0-10V or 0-20mA. At this
moment, Pr.03-19 will be invalid.
When Pr.03-29 is set to 1, it means the voltage input to ACI terminal is for 0-10V. At this moment,
Pr.03-19 will be invalid.
When setting is 1 or 2, it will display warning code "AnL" on the keypad. It will be blinking until the
