7.13 Motor feedback sensor
7.13.1. General
To minimize the possibility of electrical noise coupling into motor feedback sensor wires, avoid routing cables
next to conductors carrying high currents or high current pulses. Noise immunity may also be improved by
using twisted conductor cable for the motor feedback sensor cables from motor to the motor controller.
NOTE
Wiring of feedback sensor and the relationship between feedback sensor vs. rotational
direction depends upon feedback sensor installation in the motor. Contact the motor
manufacturer to get the correct wiring and relationship between rotational direction and
feedback sensor signals. Swapping the channels from feedback sensor will lead to improper
motor operation.
CAUTION
ESD - risk of damage to equipment
The motor feedback sensor may be ESD sensitive; see ESD related system design suggestions in
chapter 12.3.
7.13.2. Sinusoidal Motor Speed Sensor Input
The sinusoidal sensor for synchronous motors provides position, speed and direction feedback for the motor
controller. The sinusoidal analog sensor produces a single-ended two-phase sinusoidal wave output (see
Figure 13).
