Parker Releases Aries Drive with Resolver Feedback


Rohnert Park, CA, October 29, 2006 - Parker Automation announces the release of a resolver feedback option in its successful Aries family of low-cost, all-digital servo drives. The addition of resolver feedback increases the versatility of the Aries drive platform. Now users can choose the versatile Aries drive for use with resolver feedback in addition to smart encoders, quadrature encoders and Heidenhain EnDat absolute encoders.

The new resolver option adds the capability of solving applications requiring the advantages that rugged resolver technology can offer. A resolver feedback device is essentially made out of the same materials as the motor and contains no electronics; thus, a resolver- equipped motor is less susceptible to the effects of temperature, humidity, dust, vibration and shock.

In addition, the Aries family now features a total of seven distinct power levels ranging from 100W up to 3000W of continuous motor shaft power. That equates to 16A RMS continuous and 48A RMS peak current to quickly accelerate even the largest loads.

Every Aries drive contains the same standard features and benefits, including Smart Encoder feedback to automatically set up the drive, support for Endat multi-turn absolute encoders to dispense with limit switches and homing routines, and an innovative DriveTalk feature to communicate with the Aries drive without a serial connection.

All Aries drives ship with the feature-packed Aries Support Tool (AST) software package.

The AST program provides easy and intuitive diagnostic screens, graphical tuning utilities, an OS download tool and a configuration wizard for use with non-Smart Encoder motors. The AST package is provided free of charge and may be downloaded from the Parker Electromechanical Automation Web site, www.parkermotion.com. The latest release of AST is version 3.0, which offers such enhancements as the new System SnapShot feature to simplify and speed drive diagnostics; improvements to the graphical current, velocity, and notch filter tuning utilities; and improved and expanded status panel information.
