Copley offers a complete range of high-power density digital
drives for brushless, brush and stepper motors. Both AC- and DC-powered
versions are available. Xenus, Accelnet and Stepnet feature
CANopen for distributed control. PLUS versions incorporate EtherCAT as
well as CANopen and offer expanded feedback options.
PLUS drives feature high resolution A/D converters
for optimal current control as well as fast, hardware-based position capture
and setpoint trigger output.
Feedback- Incremental Encoders Digital incremental encoder
and Halls are the standard interface on all drives with position mode
capability. Xenus and Accelnet feature an analog encoder option and incorporate
a wake-and-wiggle algorithm for commutation without Halls.
- Resolvers Resolvers are the feedback of
choice for rugged environments. Available as an option on Xenus and Accelnet,
Copley’s proprietary interface delivers 14- bit resolution up to 10,000 RPM.
- Absolute Encoders Select Copley drives are
available with a range of open standard absolute encoder interfaces including
EnDat, BiSS and SSI.
Safe Torque Off
The Safe Torque Off
capability of PLUS Panel drives eliminates the expensive contactors and complex
wiring traditionally used in safety critical applications. Safe Torque Off
provides two drive enable inputs facilitating system conformance to SIL 3 (IEC
61800-5-2) & Category 3 PLd (ISO 13849-1).
