User Manual

Parameters p0777 … p0780 are assigned to an analog output via their index, e.g. parameters
p0777[0] … p0770[0] belong to analog output 0.
Table 6-7 Parameters for the scaling characteristic
Parameter Description
p0777 x coordinate of the 1st characteristic point [% of p200x]
p200x are the parameters of the reference variables, e.g. p2000 is the reference speed.
p0778 y coordinate of the 1st characteristic point [V or mA]
p0779 x coordinate of the 2nd characteristic point [% of p200x]
p0780 y coordinate of the 2nd characteristic point [V or mA]
Setting the characteristic
You must define your own characteristic if none of the default types match your particular
application.
Application example
Via analog output 0, the inverter should convert a signal in the value range 0 % … 100 % into
an output signal 6 mA … 12 mA.

Figure 6-9 Characteristics for the application example
Procedure
1. Set p0776[0] = 2
This defines analog output 0 as a current output.
2. Set p0777[0] = 0.0 (x1)
3. Set p0778[0] = 6.0 (y1)
4. Set p0779[0] = 100.0 (x2)
5. Set p0780[0] = 12.0 (y2)
The characteristic for the application example is set.
