Copley Controls: Xenus Panel XES-230-36

The Xenus Panel XES provides 100% digital control of brushless or brush motors in an off-line powered package. It can operate from single or three-phase mains with continuous power output to 4 kW.
Xenus operates as a Motion Control Device under the DSP-402 protocol of the CANopen over EtherCAT (CoE). The DSP-402 mode supports the following protocols:

• Profile Position • Profile Torque • Profile Velocity • Interpolated Position (PVT) • Homing

The Profile Position mode does a complete motion index on command with S-curve acceleration and deceleration, top speed, and distance programmable. In PVT mode, the drive uses cubic polynomial interpolation to “connect the dots” such that the motor reaches each point (Position) at the specified velocity (Velocity) at the prescribed time (Time). Cyclic Synchronous Position (CSP) mode.

Drive commissioning is fast and simple using CME software operating under Windows® communicating with Xenus via EtherCAT or an RS232 link. Address Alies selection is used by a rotary switch. Additional address bits needed can originate from programmable inputs, or they can be set in flash memory.

Three programmable logic outputs are used for reporting a drive fault or other status indications. A fourth optically-isolated output can drive a motor brake from the external +24 Vdc power supply or can be programmed as a logic output.

In addition to EtherCAT motion commands, Xenus can operate as a stand-alone drive. Current and velocity modes accept ±10 Vdc analog, digital 50% PWM or PWM/polarity inputs. In Position mode, inputs can be incremental position commands from step-motor controllers in Pulse/Direction or CW/CCW format, ±10 Vdc analog, or they can be A/B quadrature commands from a master-encoder. Pulse to position ratio is programmable for electronic gearing.

The power output of the drive varies with the input power which can range from 100 to 240 Vac, and from 47 to 63 Hz. Either single or three phase mains can be used giving Xenus the ability to work in the widest possible range of industrial settings. Signal and control circuits are isolated from the high-voltage power supply and inverter stage that connect to the mains. The +24 Vdc input powers control circuits for keep-alive operation permitting the drive power stage to be completely powered down without losing position information or communications with the control system.
