Single axis controller
September 21, 2008 by Manufacturing AUTOMATION
Danaher Motion has introduced the Dover DMM-101 Single Axis Controller and ST1 Air Bearing Spindle product set. The DMM-101 and ST1 are engineered to form a perfectly matched and easily integrated sub-system solution for hard disk drive (HDD) applications, but can also be sold separately. The DMM-101 single axis controller delivers velocity stability performance (0.0006 per cent at 7200 RPM) to provide a stable test platform for increased aereal track densities. Its flexible connector interface accepts both MCS-LA2000 and MFM-BDC-610 connections, making it well suited as a drop-in replacement in todayÃs media testers. User adjustable PID gain adjustments optimize performance with any payload. Additionally, the DMM-101 can position the spindle to any encoder count within one revolution relative to the index, while enabling users to simplify commutation by eliminating the need to align the encoder index to a motor pole.
