Chapter 12 Description of Parameter SettingsCFP2000
Analog Input Gain (AVI1)
Analog Input Gain (ACI)
Analog Positive Input Gain (AVI2)
Analog Negative Input Gain (AVI2)
Settings
Use Pr.03-03–Pr.03-14 when the frequency command source is the analog voltage or current
signal.
Analog Input Filter Time (AVI1)
Analog Input Filter Time (ACI)
Analog Input Filter Time (AVI2)
Settings
Use these input delays to filter a noisy analog signal.
When the time constant setting is too large, the control is stable but the control response is slow.
When the time constant setting is too small, the control response is be faster but the control may
be unstable. For optimal setting, adjust the setting based on the control stability or the control
response.
Analog Input Addition Function
Settings
When Pr.03-18 is set to 1:
EX1: Pr.03-00=Pr.03-01=1, Frequency command= AVI1+ACI
EX2: Pr.03-00=Pr.03-01=Pr.03-02=1, Frequency command = AVI1+ACI+AVI2
EX3: Pr.03-00=Pr.03-02=1, Frequency command = AVI1+AVI2
EX4: Pr.03-01=Pr.03-02=1, Frequency command = ACI+AVI2
When Pr.03-18 is set to 0 and the analog input setting is the same, the priority for AVI1, ACI and
AVI2 are AVI1>ACI>AVI2.
