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.

ANALOG ENCODER (-S MODELS)
Xenus supports analog encoder signals for position feedback. The Sin and Cos inputs
are differential with 121 Ω terminating resistors and accept 1.0 Vp-p signals in the
A/B format used by encoders with analog outputs such as Heidenhain, Stegman,
and Renishaw. When Copley’s ServoTube motors are used the analog encoder
supplies both commutation and incremental position feedback.
DIGITAL ENCODERS
The quad A/B encoder interface is a differential line-receiver with R-C ltering on
the inputs. Encoders with differential outputs are required because they are less
susceptible to noise that can degrade single-ended outputs. Encoder cables should
use twisted-pairs for each signal pair: A & /A, B & /B, X & /X. An overall shield
should be used, and for longer cables, shields for individual pairs may be necessary
to guarantee signal integrity.

MOTOR TEMPERATURE SENSOR
Digital input [IN5] is for use with a motor overtemperature switch. The input should
be programmed as a pull-up to +5 Vdc if the motor switch is grounded when cold,
and open or high-impedance when over-heating.

for CE compliance
BRAKE OUTPUT [OUT4]
This output is an open-drain MOSFET with an internal yback diode connected to
the +24 Vdc input. It can sink up to 1A from a motor brake connected to the +24
Vdc supply.
The operation of the brake is programmable with CME 2. It can also be programmed
as a general-purpose digital output.
