● When you use analog input as the PID reference target input, you must set Pr.00-20 to 2 (external analog
input).
– Setting method 1: Pr.03-00–03-01 set 1 as PID reference target input.
– Setting method 2: Pr.03-00–03-01 set 4 as PID reference target input.
● If the setting value 1 and setting value 4 exist at the same time, the AVI input has highest priority to become the
PID reference target input value.
● When you use analog input as the PID compensation value, you must set Pr.08-16 to 1 (source of PID
compensation value is analog input). You can see the compensation value with Pr.08-17.
● When using the Frequency command, the corresponding value for 0–10 V / 4–20 mA is 0–maximum operation
frequency (Pr.01-00).
● When using the torque command, the corresponding value for 0–10 V / 4–20 mA is 0–maximum output torque
(Pr.11-27).
● When using torque compensation, the corresponding value for 0–10 V / 4–20 mA is 0–the motor’s rated torque.
● If the settings for Pr.03-00–Pr.03-01 are the same, the AVI input has priority over the ACI input.
