Analog Inputs
The Quattro DC has two non-programmable
differential analog input channels.
 Analog input channel 1 is reserved for the
speed command (if used).
 Analog input channel 2 is reserved for the
pre-torque command (if used) or torque
command source (if used).
The analog input channels are bipolar and have
a voltage range of 10VDC.
Available with the analog channels is multiplier
gain parameters (SPD COMMAND MULT and
EXT TORQUE MULT) and bias parameters
(SPD COMMAND BIAS and EXT TORQUE
BIAS). These parameters are used to scale the
user’s analog command to the proper range for
the drive software. The formula below shows
the scaling effects of these two parameters.
