Omron SIGMA LINEAR AXIS DATASHEET
LETLA-@-F@
Sigma linear axis
Linear servo axis ready to use
• Highly enclosed construction avoids falling parts
into the magnets and bearings area
• Plug and drive, shorten start-up time
• Long durability, reliable and constant performance
after years of use
• Designed for an easy servicing
• Direct control of the axis using XtraDrive and
Sigma-II drives
• Extremely energy efficient, due to its optimised
magnetic circuitry design and high-density winding
• For special lenghts, special specifications and XY
systems contact your OMRON sales office
Ratings
• 230 VAC Single-phase 80 to 560 N (1200 N peak)
• 400 VAC Three-phase 80 to 1200 N (2400 N peak)
