Scaling the User-configurable Analog Output
You define the scaling for the analog output by entering analog output voltages
into Analog Out1 Lo and Analog Out1 Hi. These two output voltages
correspond to the bottom and top of the possible range covered by the quantity
being output. The output voltage varies linearly with the quantity being output.
The analog output voltage does not go outside the limits defined by Analog Out1
Lo and Analog Out 1 Hi. See
Table 8 .
Table 8 - Analog Output Scaling
If Analog Out1 Sel (342) is set to Application (14), and the drive is a Frame 3
drive (firmware version 1.x), then the source of the analog output value is the
value in Appl Analog Out (31), and the values entered in that parameter can
range from 4.000 mA (resulting in an analog output level corresponding to
Analog Out1 Lo) to 20.000 mA (resulting in an analog output level
corresponding to Analog Out1 Hi).
If Analog Out1 Sel (342) is set to Application (14), and the drive is a Frame 4
drive (firmware version 2.x), then the value entered in Appl Analog Out (31) is
output directly on the analog output, irrespective of the values of Analog Out1
Hi (343) and Analog Out1 Lo (344).
Options Analog Out1 Lo Value Corresponds to: Analog Out 1 Hi (343)
Value Corresponds to:
Analog Out Absolut
(341) = Disabled Analog Out Absolut
(341) = Enabled
