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
Factory Setting: 0
Settings 0: Disable (AVI1, ACI, AVI2)
1: Enable
 When Pr03-18 is set to 1:
EX1: Pr03-00=Pr03-01=1 Frequency command= AVI1+ACI
EX2: Pr03-00=Pr03-01=Pr03-02=1 Frequency command = AVI1+ACI+AVI2
EX3: Pr03-00=Pr03-02=1 Frequency command = AVI1+AVI2
EX4: Pr03-01=Pr03-02=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.

Treatment to 4-20mA Analog Input Signal Loss
Factory Setting: 0
Settings 0: Disable
1: Continue operation at the last frequency
2: Decelerate to stop
3: Stop immediately and display ACE
 This parameter determines the behavior when 4~20mA signal is loss, when AVIc(Pr.03-28=2) or
ACIc (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
loss of the ACI signal is recovered.
 When the motor drive stops, the condition of warning does not exist, then the warning will
disappear.
