Description:
It determines the analog outputs gain according to the equations of Table 12.4 on page 12-8 .
P253 - AO1 Signal
P256 - AO2 Signal
Adjustable
Range:
0 = 0 to 10 V
1 = 0 to 20 mA
2 = 4 to 20 mA
3 = 10 to 0 V
4 = 20 to 0 mA
5 = 20 to 4 mA Factory
Setting:
0
Properties:
Description:
These parameters configures if the analog outputs signal will be in current or voltage, with direct or reverse
reference.
Table 12.4 on page 12-8 below summarizes the configuration and equation of the analog output, where the
relationship between the analog output function and the full scale is defined by P251 (AO1) or P256 (AO2), as
per
Table 12.3 on page 12-7 .
