Encoder Driver Module

Instructions

Quadrature Encoder/ Impedance Isolation – Figure 3 depicts a single

quadrature encoder used for impedance isolation of the drive feedback

input signal on an AC drive. In this case, the feedback input signal of a

1399 AC drive is isolated from other controllers using the same encoder

signals, which are creating common loops resulting in noise interference

with the feedback signals of the 1399 drive.
