7.4.2 Parameters For Analog Torque Mode
SV200 series DC servo drives have 2 12-bit analog A/D converters. When single-ended input signals are used, analog input 1 (ANA1)
is used for the velocity command, and analog input 2 (ANA2) is used for the rotating toque command. Differential input via ANA1/
ANA2 is also available. In addition, a low pass filter, analog offsets and deadband values can be set to the drive.
