MOTOR CONNECTIONS (CONT'D)
DIGITAL ENCODERS
The quad A/B encoder interface is a differential line-receiver with R-C filtering 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.
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.
ANALOG HALLS (-S MODELS) + DIGITAL ENCODER
For position feedback with higher resolution than is possible
by interpolating analog Halls, a digital incremental encoder
is connected to the multi-mode port. The Halls are then used
for commutation and the multi-mode port is programmed as a
differential input for the Secondary Incremental motor encoder.
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.
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.
BRAKE OUTPUT [OUT4]
This output is an open-drain MOSFET with an internal flyback 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.
