section Drive A1 submenu on page 30.
Analog Outputs
The Quattro DC has two programmable
differential analog output channels. The two
analog output channels were designed for
diagnostic help.
For more information on
programming the analog output channels, see
Analog Outputs C4 submenu on page 65.
The connection of these two outputs is shown in
Figure 12: Analog Outputs.
The analog output channels are bipolar and
have a voltage range of
±10VDC and current
draw of +/- 4mA.
Available with the analog channels is multiplier
gain parameters (ANA 1 OUT GAIN and ANA 2
OUT GAIN) and a bias or offset parameters
(ANA 1 OUT OFFSET and ANA 2 OUT
OFFSET). These parameters are used to scale
the user’s analog outputs to the proper range
for the drive software. The formula below
shows the scaling effects of these two
parameters.
