MoToR ConnECTionS
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 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:

ANALOG SIN/COS INCREMENTAL ENCODER
The sin/cos/index 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
ServoTube motors.

Xenus
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

RESOLVER (-R MODELS)
Connections to the resolver should be made with
shielded cable that uses three twisted-pairs. once
connected, resolver set up, motor phasing, and other
commissioning adjustments are made with CME 2
software. There are no hardware adjustments.
