Servoamplifiers provide all-digital, multi-axis motion control.
Press Release Summary:
Accelnet(TM) networked servoamplifiers communicate with control PC and with each other via 2-wire CAN bus. They drive brush and brushless servomotors and close position and velocity feedback loops locally, eliminating dedicated motion controller. Five versions operate from 55 V at 18 A peak to 180 V at 20 A peak. Amplifiers provide sinusoidally commutated motor drive, as well as Field Oriented Motor control. Software libraries speed system creation and commissioning.
Original Press Release:
Networked Servoamplifiers Change Face of Multi Axis Motion Control, Cut Cost, Simplify Design of Automation Systems
Networked servoamplifiers pioneer new all-digital multi-axis motion control architecture, slash system cost and complexity. Software libraries eliminate "wheel reinventing," speed system creation and commissioning
Motion Control Innovation
Canton, MA, March 18, 2003 -- Copley Controls' networked Accelnet(TM) servoamplifiers change the way equipment builders design automation systems involving multiple drive motors. Networked all-digital servoamplifiers communicate with control PC-and with each other-via simple 2-wire CAN bus. Accelnet(TM) servoamplifiers eliminate traditional dedicated motion controller by closing individual servo loops within the amplifier itself. Eliminating the controller, as well as unwieldy and labor intensive cabling, slashes cost, bulk and complexity of multi-axis automation. Technicians--rather than engineers--can now handle installation, debugging and system commissioning.
Applications
Accelnet(TM) servoamplifiers cut cost of multi-axis motion controls in a wide range of robotics and automation systems. Examples include semiconductor fabrication, testing and packaging. Assembly lines for PCBs and hand held electronic devices are ideal candidates for networked simplification. Genome research is emerging as a potent application for high performance pick and place automation.
Benefits
o The all-digital servoamplifier, networked by simple 2-wire bus, and commanded by libraries of networking software, transform creation of multi-axis drive into plug-and-play function. Technicians rather than EEs, can now handle installation, debugging, and system commissioning
o Eliminating the rats nest of bulky cables, controllers, and connection boxes leads to a simpler and physically smaller machine.
o More (smaller) machines can be built in a given facility...no need to move to a larger plant as sales expand
o Fewer workers needed to build new pick-and-place designs, reducing cost, enhancing sales
o Smaller, simpler machines are built faster, cutting cost, speeding delivery, and capturing market share
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 commissioning 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. Reduced system complexity brings important cost and performance benefits to assembly, fabrication, test, and inspection automation.
Servoamplifier Highlights
Accelnet(TM) servoamplifiers drive brush and brushless servomotors, including modern linear types. The amplifiers are compatible with the CANopen networking protocol, which enables them to be linked via a common 2-wire bus and CAN communications card. The Accelnet(TM) servoamplifiers close position and velocity feedback loops locally, eliminating dedicated motion controller. The amplifiers are controlled by a PC that delivers motion commands over the CAN bus.

Specifications
The Accelnet(TM) servoamplifier family covers five versions that operate from 55V at 18A peak to 180V at 20A peak. The amplifiers provide sinusoidally commutated motor drive, as well as Field Oriented Motor control. DSP-based technology puts powerful setup and system configuration benefits at the user's fingertips.
Accelnet(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 14 kHz current loop update rate (71.4 µs) and 3.5 kHz (286 µs) position and velocity loop update rate.
Mechanical Design, Protection
Accelnet(TM) servoamplifiers are designed with solderless power and signal connections, and are built in PCB-mounting packages measuring 2.62" (66.5) wide x 4.05" (102.7) wide x 0.98" (24.9) high. 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 I2*T heating effect of load current, enable motor to run safely at its outer performance envelope.
Automated Setup And Commissioning
Accelnet(TM) users invoke CME 2 software to perform automatic current loop and voltage loop tuning. A further user-initiated algorithm performs motor, Hall, and encoder phasing. All CME 2 programming commands are stored in the amplifier's non-volatile flash memory.
