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 83.
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.
