6.3 Adapt the default setting of the terminal strip
Parameters p0777 ... p0780 are assigned to an analog output via their index, e.g. parameters
p0777[0] ... p0770[0] belong to analog output 0.

Setting the characteristic
You must define your own characteristic if none of the default types match your particular
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.
Procedure
Defining the function of an analog output
You define the analog output function by interconnecting parameter p0771 with a connector
output of your choice. Parameter p0771 is assigned to the particular analog output via its index,
e.g. parameter p0771[0] is assigned to analog output 0.

Parameters for the scaling characteristic
Description
x coordinate of the 1st characteristic point [% of p200x]
p200x are the parameters of the reference variables, e.g. p2000 is the reference speed.
y coordinate of the 1st characteristic point [V or mA]
x coordinate of the 2nd characteristic point [% of p200x]
y coordinate of the 2nd characteristic point [V or mA]
Connector outputs (CO) of the inverter (selection)
Meaning
Actual speed smoothed
Output frequency, smoothed
Output voltage smoothed
Set the following parameters to set the characteristic to
match the example:
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)
CO Meaning
r0026 DC link voltage smoothed
r0027 Absolute actual current smoothed
