12-

03 Analog Input/Output Parameter  This parameter can be set during operation.



Analog Input Selection (AVI)

Factory Setting: 1



Analog Input Selection (ACI)

Factory Setting: 0



Analog Input Selection (AUI)

Factory Setting: 0

Settings

0: No function

1: Frequency command (speed limit under torque control mode)

2: Torque command (torque limit under speed mode)

3: Torque compensation command

4: PID target value

5: PID feedback signal

6: PTC thermistor input value

7: Positive torque limit

8: Negative torque limit

9: Regenerative torque limit

10: Positive/negative torque limit

11: PT100 thermistor input value

12: Reserved

13: PID compensation value

14~17: Reserved

 When use analog input as PID reference value, Pr00-20 must set 2(analog input).

Setting method 1: Pr03-00~03-02 set 1 as PID reference input

Setting method 2: Pr03-00~03-02 set 4 as PID reference input

If the setting value 1 and set value 4 existed at the same time, AVI input has highest priority to

become PID reference input.

 When use analog input as PID compensation value, Pr08-16 must set 1(Source of PID

compensation is analog input). The compensation value can be observed via Pr08-17.

 When it is frequency command or TQC speed limit, the corresponding value for 0~±10V/4~20mA is

0 – max. output frequency(Pr.01-00)

 When it is torque command or torque limit, the corresponding value for 0~±10V/4~20mA is 0 – max.

output torque (Pr.11-27).

 When it is torque compensation, the corresponding value for 0~±10V/4~20mA is 0 – rated torque.
