Aerotech's new Soloist SC spindle controller is an integrated control, drive and power supply for high accuracy single axis speed control applications. With dual 32 MHz encoder input capability and speed up to 30,000 rpm, the Soloist SC can return a velocity regulation specification of better than 0.0001%.
To maintain such high precision, the Soloist SC makes full use of Aerotech's linear amplifier power stage technology which has a much improved linearity and bandwidth potential than PWM drive stage alternatives. This DSP based linear amplifier type is already used extensively for nanometre level positioning applications with excellent rate stability and extremely 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 stand-alone 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 powerful diagnostics and program development tools for speed control.
The Soloist SC also includes a direct-on-line power supply for an 85-240 VAC 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 own range of direct drive, air bearing spindles for disk drive testing, imaging and precision wafer inspection applications. |
