6.7 Analog Reference Parameters (Group P6)
This function is used to define the analog input range and target range. Four curves are provided for
users. Three of curves have a linear correspondence and one curve have four-point correspondence.
The setting should according actual requirement.
P6.00 AIT to AI3 and DI input curve selection
Ones place
AIT input curve selection:
0: Reference frequency determined by curve T (P6.0T ~ P6.04)
T: Reference frequency determined by curve T (P6.05 ~ P6.08)
T: Per unit value determined by curve 3 (P6.09 to P6.TT)
3: Per unit value determined by curve 4 (P6.T3 to P6.T0)
4: NONE
Tens place AIT input curve selection: Same as above
Hundreds place AI3 input curve selection: Same as above
Thousands place DI input curve selection: Same as above
Curve T can be used to directly realize the corresponding relationship between the analog input value
and the reference frequency.
Curve T and curve T are the same usage method.
Curve 3 and curve 4 can be used to convert the externally input analog value into internal per unit value.
All the input analog functions are programmable setting by P6.TT.
Note:

AIT ~ AI3 and DI values can be displayed through setting PT.0T or PT.03, DI displayed unit is %, the
maximum input pulse frequency P5.T0 corresponding to T00.0%.

When analog curve “NONE” is selected, the maximum analog input or maximum pulse frequency
input corresponding to the maximum output frequency P0.TT or T00.0% per unit value.
Since the using methods of curve T and curve T are identical, Curve T is described as an example here.
Both curve T and curve T can be used as process open loop frequency reference, and the reference
frequency can be determined by the analog values AIT, AIT, AI3 or DI pulse frequency. The relationship
between analog value and setup frequency is as shown in the following figures.
