Settings
0: No function
1: Frequency command
2: Torque command (torque limit in speed mode)
3: Torque compensation command
4: PID target value
5: PID feedback signal
6: Thermistor input value (PTC)
7: Positive torque limit
8: Negative torque limit
9: Regenerative torque limit
10: Positive / negative torque limit
11: PT100 thermistor input value
12: Auxiliary frequency input
13: PID compensation value
14: Tension PID feedback signal
15: Line speed
16: Reel diameter
17: Tension PID target value

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 frequency command.
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 you use the frequency command, the corresponding value for 0– ±10 V / 4–20 mA is 0–
maximum operation frequency (Pr.01-00).
When you use the torque command, the corresponding value for 0– ±10 V / 4–20 mA is 0–
maximum output torque (Pr.11-27).
When you use torque compensation, the corresponding value for 0– ±10 V / 4–20 mA is 0–the
rated torque.
