Design Features

Introduction

Aerotech’s Soloist® PWM series are single-axis servo controllers that combine a power supply, amplifier, and position controller in a single package. The Soloist can control up to five tasks simultaneously, as well as handle variables and manage I/O, making it well-suited for demanding production applications. The Soloist has high-speed position latch inputs and advanced data logging capabilities, making it ideal for laboratory, test instrument, and industrial applications. The advanced software architecture shortens customer development time, while including support for C#, VB.Net, C, and LabVIEW®, combined with our full IDE and multitasking operating system. Host-mode operation allows you to send commands with your PC via Ethernet or USB for immediate execution.

The Soloist MP offers the same advanced software as the CP but in a smaller package designed for OEMs that can supply bus power from existing power supplies.

The Soloist HPe can be used for larger systems requiring up to 150 A peak current.

Motion Composer, the common integrated development environment for all Aerotech controllers, provides users with Windows®-based software with powerful diagnostic, debug, and analysis tools for OEMs and end users alike.

Allen-Bradley Interface

Combine proven PLC with proven motion control for easier integration, startup, and maintenance of medium- and highend automation projects. The Aerotech EtherNet/IP™ interface enables AB PLCs (MicroLogix, CompactLogix™, or ControlLogix) to be integrated directly with the Soloist. Motion can be directly programmed in the RSLogix 5000 environment or separate programs can be written on the controller and triggered from the AB PLC. Aerotech has two interfaces: ASCII and Register. Choose the PLC, motion controller, and interface that best fits your application needs.

Total Solution

The controllers are fully tested and ready to run right out of the box. Aerotech can integrate the Soloist into a complete motion system, removing the burden of parameter setup and axis tuning.

Practical Power

Each series is capable of driving a wide range of motors including brushless, DC servo, and steppers. Brushless motors are sinusoidally commutated to minimize torque ripple.

Using a digital servo loop with feedforward, the Soloist tightly tracks velocity and position trajectories with virtually zero error. On-board autotuning and built-in calculators make servo tuning simple.

Variables, Math and More

With variables and math capability, one program can be used to produce a variety of parts by simply prompting the user for new application data.

Application Versatility

The Soloist has other built-in features such as axis calibration and backlash compensation, so you can maximize your machine’s accuracy and precision. The “user units” feature makes it easy to customize the Soloist to your specific machine, allowing custom units for both linear and rotary applications. The controller is equipped with dual encoder inputs, so you can tackle master-slave applications or achieve higher accuracies with dual-loop control. Precise registration-based moves are also possible because of the fast 0.1 microsecond acknowledge time of the Soloist. The Soloist easily handles complex functions such as output-on-the-fly and velocity profiling.

  1. For stepper motors only, one-half of bus voltage is applied across the motor (e.g., 80 VDC supply results in 40 VDC across stepper motor).

  2. "Keep Alive" supply.

  3. Output voltage dependent upon input voltage.

  4. Peak value of the sine wave; rms current for AC motors is 0.707 * A pk.

  5. Requires I/O option.

  6. Requires external relay to remove motor supply power.
