84 Chapter 6 Parameter Descriptions
Curve 3 have a linear correspondence and curve 4 have four-point correspondence.
The input analog characteristics curve as shown in the following figure. Curve 4 is described as an
example here.
Curves 3 and 4 convert the externally input analog into the internal value. All the AI and DI inputs will be
converted to percentage. The maximum analog input or maximum pulse frequency input corresponding
T00.0% per unit value.
The function of per unit value is determined by the analog channel function selection P6.TT.
Figure 6−T4 Input analog characteristics curve
P6.TT is used to select functions of AIT, AIT, AI3 and DI input. The using methods of AIT, AIT, AI3 and DI
are identical.

0: Open loop frequency reference, analog close loop reference, close loop feedback.
For open loop frequency reference, refer to the parameter description of P0.04.
For analog close loop reference, refer to the parameter description of PT.0T, PT.03.
For analog close loop feedback, refer to the parameter description of PT.05, PT.06.
5: Motor temperature feedback: It is used together with parameter P9.T7 for motorthermal protection.

Note:
If the analog channel function is set a non−zero value, please make sure that different analog channels
have different functions.
