Aerotech spindle controller offers high precision

An Aerotech product story
Edited by the Engineeringtalk editorial team Aug 4, 2009

Aerotech's Soloist SC spindle controller is an integrated control, drive and power supply for high-accuracy single-axis speed control applications.

With dual 32MHz encoder input capability and speed up to 30,000rev/min, the Soloist SC can return a velocity regulation specification of better than 0.0001 per cent.

To maintain this high precision, the Soloist SC makes full use of Aerotech's linear amplifier power stage technology, which has improved linearity and bandwidth potential than PWM drive stage alternatives.

This DSP-based linear amplifier type is already used for nanometre-level positioning applications with high rate stability and quiet EMC characteristics that are also of high importance for exacting speed control applications for metrology, test and ultra-high-precision machining in microelectronics and optical component manufacturing.

The Soloist SC can run standalone for pre-programmed velocity control or in host mode where speed and related commands are sent through integral Ethernet or USB ports from a host PC.

The SC can also provide full networking access in this way.

Aerotech's Windows-based IDE (Integrated Development Environment) software is included with the Soloist SC, providing diagnostics and program development tools for speed control.

The Soloist SC also includes a direct-on-line power supply for an 85-240V AC input.

The 10A peak, 5A continuous current drive also includes fault, brake and relay outputs and will interface with step and direction clock sources.

Aerotech's Soloist SC may be used with third-party brushless-motor-driven spindles or supplied complete with Aerotech's range of direct drive, air bearing spindles for disk drive testing, imaging and precision wafer inspection applications.
