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 (torque 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 Offset (%) (h.)
14~20: 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.
