Motor connectIons: encoder & resolVer
Motor connections are of three types: phase, feedback, and thermal sensor. The phase connections carry the drive output currents that
drive the motor to produce motion. A thermal sensor that indicates motor overtemperature is used to shut down the drive to protect the
motor. Feedback can be digital quad A/B encoder, analog sin/cos encoder, resolver or digital Halls, depending on the version of the drive.
QUAD A/B EnCoDER WiTH FAUlT PRoTECTion
Encoders with differential line-driver outputs are required (single-ended encoders are not supported) and provide incremental position feedback via
the A/B signals and the optional index signal (x) gives a once per revolution position mark. The MAx3097 receiver has differential inputs with fault
protections for the following conditions:
Short-circuits line-line:
Open-circuit condition:
Low differential voltage detection:
±15kV ESD protection:
Extended common-mode range:

Double-shielded cable is recommended for resolvers and analog sin/cos encoders. The outer shield connects to the motor and drive
frames. The inner shield(s) should only connect to the Signal Ground at the drive. The inner shields shown here are for individually
shielded twisted-pair cables. If the inner shield is a single one, it connects to Signal Ground at the drive.
The inner shield should have no connection at the motor, or the the outer shield. Double-shielding is used less frequently for digital
encoders, but the connections are shown here and on following pages for completeness.
ANAlOG SIN/COS INCREMENTAl ENCODER
The sin/cos/idx inputs are differential with 121 Ω terminating
resistors and accept 1 Vp-p signals in the format used by
incremental encoders with analog outputs, or with
motors.

PLUS
This produces a near-zero voltage between A & /A which is below the differential fault threshold.
The 121Ω terminator resistor will pull the inputs together if either side (or both) is open.
This will produce the same fault condition as a short-circuit across the inputs.
This is possible with very long cable runs and a fault will occur if the differential input voltage is < 200mV.
The 3097E has protection against high-voltage discharges using the Human Body Model.
A fault occurs if the input common-mode voltage is outside of the range of -10V to +13.2V
