Chapter 12 Description of Parameter SettingsME300
Analog Input Filter Time (AVI)
Analog Input Filter Time (ACI)
Default: 0.01
Settings
0.00–20.00 sec.
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 faster but the control
may be unstable. For optimal setting, adjust the setting based on the control stability or the
control response.
Signal Loss Selection for the Analog Input 4–20 mA
Default: 0
Settings 0: Disable
1: Continue operation at the last frequency
2: Decelerate to 0 Hz
3: Stop immediately and display “ACE”
Determines the treatment when the 4–20 mA signal is lost, when ACIc (Pr.03-28 = 0).
When Pr.03-28 ≠ 2, the voltage input to AVI terminal is 0–10 V or 0–20 mA, and Pr.03-19 is invalid.
When the setting is 1 or 2, the keypad displays the warning code “ANL”. It keeps blinking until the
ACI signal is recovered.
When the motor drive stops, the warning condition does not continue to exist, so the warning
disappears.
AFM Analog Output Selection
Default: 0
