Networked Offline Servo Amp Drives Motors To 5 kW



Canton, MA, May 21, 2003 -Copley Controls announces the Xenus family of high power (5 kW) CANopen networking servo amplifiers for driving brushless and brush motors, including linear motors. Built-in power supply enables the amplifiers to dispense with separate DC supply, runs on single or three-phase 85 - 264VAC. Xenus amplifiers permit sinusoidal or trapezoidal motor commutation and will also drive DC brush motors. The new amplifiers strengthen Copley's family of networked servo amplifiers by extending drive power beyond the range of Copley's recently announced Accelnet(TM) amplifiers. Motors driven by Xenus amplifiers are supported by software that's fully tested with third party communications cards and I/O. Besides their networked operating mode, the amplifiers work as stand-alone drives for single axis motion control. As stand alone drivers, Xenus amplifiers respond to a variety of input formats, including step-and-direction commands for upgrading from stepper motors to high torque servomotors.

Built In DC Supply
Xenus amplifiers have a built-in DC supply that operates from 50/60 Hz supply at 85V - 264V. single or 3-phase. This offline operation simplifies multi axis automation, in which one high power motor may work with a host of smaller drives. (Multiple smaller motors perform assembly operations; a single larger motor positions heavy parts;). Most drives would run on a common low voltage DC supply, while the higher power drive would ordinarily require its own high voltage supply. However, with its plug-into-the-wall powering, the Xenus amplifier makes a separate DC supply unnecessary. In stand-alone operation too, power supply elimination is a major cost saving.

Xenus Networking Benefits
Networked all-digital Xenus(TM) amplifiers close the local feedback loop within the amplifier itself, which eliminates the need for a separate motion controller. Also eliminated are multi-conductor cables-their labor-intensive connections- between controller and individual amplifiers. Instead, with networked control of multi-axis motion, a low cost two-wire CAN bus provides the link between amplifiers and control PC. Cost saving amount to 30% - 50% of traditional analog multi-axis systems

Software Libraries Speed System Implementation
Copley Controls has developed extensive libraries of motion control software (Copley Motion Libraries) and software COM objects (COM) to make system development fast and simple. The development of low level code to control a CANopen network of intelligent drives is eliminated. All network housekeeping is taken care of automatically by a few simple commands linked into the user's Visual Basic, Labview or C++ application program.

Stand Alone Operation
Besides their role in networked multi-axis motion control, Xenus amplifiers also function in stand-alone mode for single axis automation, including stepper to servo upgrade. With no need for a DC power supply, Xenus amplifiers provide economy and simplicity for high power single axis applications.

Xenus amplifiers also give the user a wide range of stand-alone control options. In position mode, the amplifiers accept CW/CCW inputs, pulse & direction inputs, and quadrature encoder inputs for electronic gearing. For torque and velocity mode operation, the amplifiers respond to ±10v analog commands, PWM signals with polarity information, and direct 50% PWM modulation of the power semiconductors.

CME 2(TM) Software Automates System Setup
Xenus(TM) users automate otherwise time-consuming system setup and commissioning functions with Copley's CME 2(TM) software. The software, loaded into the user's computer, provides auto tuning of the amplifier's current loop and auto phasing of the motor's Hall sensors. With setup and tuning completed, the software settings are stored in the amplifier's non-volatile flash memory.

Specifications
Xenus(TM) amplifiers use the advanced carrier cancellation modulation (CCM) for utmost zero crossing linearity. A further benefit of carrier cancellation modulation is ultra low ripple current, which occurs at twice the carrier (PWM) frequency. Ripple frequency is 28 kHz. Current loop bandwidth is 2.5 kHz. The amplifier provides 15 kHz current loop update rate (67 µs) and 3 kHz (333 µs) position and velocity loop update rate. Xenus amplifiers are available for peak current from 18A to 40A, and operate from 85 - 264VAC single or three-phase line voltages.

Mechanical Design, Protection
Xenus(TM) servo amplifiers are built in metal enclosed packages measuring 2.55" high x 5.4" wide x 7.55" long. The amplifiers are protected against over-current, over-temperature, and incorrect operating voltages. They are further protected from short circuits between outputs, from output to ground, against over-current, over-temperature, and against incorrect operating voltages. In addition, protection circuits guard against loss of signal from either the encoder or the motor's Hall sensors. Built-in computation algorithms monitor the I2oT heating effect of load current, enable motor to run safely at its outer performance envelope.

Applications
Xenus(TM) servo amplifiers drive high power motors (to 3 kW) in stand alone operation, and in multi axis networked automation. A built in DC supply that operates from single phase or three phase 50/60 AC simplifies system design.
