DESCRIPTION
Accelus is a 100% digital servoamplifier in a panel-mount
package with a family of power options to 12A continuous
and 36A peak. This new series offers sinusoidal commutation
of brushless motors in torque, velocity, or position modes
and fast, easy set up with CME 2™ software.
CME 2™ software communicates with Accelus through an
RS-232 link for complete amplifier setup. Auto-phasing
and auto-tuning algorithms in CME 2™ slash set up times
for fast system commissioning and eliminate “re-wire and
try” so common in brushless motor installations. CME 2™
automates current loop tuning, as well as motor, Hall,
and encoder phasing. A powerful oscilloscope and signal
generator display amplifier performance for fine tuning
thereafter. Amplifier control parameters are saved in nonvolatile
flash memory. OEM’s can inventory one part, and
configure amplifiers on-site to each axis in a machine.
Advanced field-oriented-control ensures the highest motor
torque over a wide speed range, minimizing motor heating
and maximizing efficiency. Digital control algorithms
transform stator currents into direct and quadrature
components. The torque-producing quadrature current is
controlled by the current loop, and the direct component is
driven to zero eliminating losses from current that doesn’t
produce torque. Space-vector modulation produces higher
speeds than sine-pwm modulation from the same power
supply.
Accelus works with motion controllers that close positionloops
using incremental encoder feedback and process
the position error in a PID filter to produce an amplifier
command for torque, force, or velocity. Only one ±10V
analog, or a one or two-wire digital PWM/DIR control signal
is required. All commutation is done in the amplifier.
In position-mode, Accelus accepts two-wire digital stepmotor
control signals (CW/CCW, or Count/Direction),
or operates as a slave from a master encoder. The ratio
between input position pulses and motor position is
programmable.
Velocity control is derived from motor encoder signals.
Velocity mode is useful not only for speed-setpoint
applications, but enables operation with PLC’s or controllers
that output position-error signals with no PID filtering.
All amplifier circuits are DC coupled and operate from
unregulated transformer-isolated DC power supplies, or
regulated switching power supplies.
The panel-mount package is compatible with the mounting
footprint of Copley’s 5xx1 series trapezoidal brushless
amplifiers, offering an easy upgrade to sinusoidal
commutation with digital control.

description
The Accelus™ servoamplifier drives DC brushless motors
in position, velocity, or torque modes with 100% digital
control. Commutation is sinusoidal using encoder feedback
from the motor. Hall signals are used for phase-initialization
and phase-correction eliminating motor hunting after
power-up.
Advanced field-oriented-control ensures the highest motor
torque over a wide speed range, minimizing motor heating
and maximizing efficiency. Digital control algorithms
transform AC stator currents into direct and quadrature
components. The torque-producing quadrature current is
controlled by the current loop, and the direct component is
driven to zero eliminating losses from current that doesn’t
produce torque. Space-vector modulation produces higher
speeds than sine-pwm modulation from the same buss
voltage.
CME 2™ software communicates with Accelus through an
RS-232 link for complete amplifier setup. Auto-phasing
and auto-tuning algorithms in CME 2™ slash set up times

Accelus™ works with motion controllers that close positionloops
using incremental encoder feedback and process the
position error in a PID filter to produce an amplifier command
for torque, force, or velocity. Only one +/-10V analog,
or a one or two-wire digital PWM/(DIR) control signal is
required. All commutation is done in the amplifier.
In position-mode, Accelus™ accepts two-wire digital stepmotor
control signals (CW/CCW, or Count/Direction), or
operates as a slave from a master encoder. The ratio between
input position pulses and motor position is programmable.
Velocity control is derived from motor encoder signals. Velocity
mode is useful not only for speed-setpoint applications,
but enables operation with PLC’s or controllers that output
position-error signals with no PID filtering.
All amplifier circuits are DC coupled and operate from
unregulated transformer-isolated DC power supplies, or
regulated switching power supplies.
The package is a single board with no heatplate. Solderless
mating connectors on pc boards mount Accelus™ at 0° or
90°. Installation and replacement is fast and doesn’t damage
amplifier connections. A Development Kit is available that
mounts 1~4 Accelus™ amplifiers and provides unregulated
DC power from an isolation step-down transformer
