Setting the characteristic of the analog output
You must define your own characteristic if none of the default types match your particular
application.
Example:
The inverter should convert a signal in the value range -100% ... 100% into a
6 mA ... 12 mA output signal via analog output 0.
Procedure
Proceed as follows to adapt the characteristic to match the example:
1. Set p0776[0] = 2.
You have defined analog output 0 as current output.
After changing p0776 = 2, the inverter sets the scaling characteristic parameters to the
following values:
p0777[0] = 0.0; p0778[0] = 4.0; p0779[0] = 100.0; p0780[0] = 20.0
2. Adapt the characteristic:
You have adapted the characteristic of the analog output to match the example.

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]
p0777[0] = 0.0 Analog output, characteristic (x
0.0% corresponds to 6 mA
p0778[0] = 6.0
p0779[0] = 100.0 Analog output, characteristic (x
100% corresponds to 12 mA
p0780[0] = 12.0
