Controllers & Drivers – AC Servo DriversLE’s AC servo motors offer higher speeds and accelerations than DC types, as well as higher torques for larger actuators. Incremental and absolute pulse input drivers are available, as well as network models for CC-Link fieldbus protocol and Mitsubishi’s SSCNET.
SMC's LECS series is an AC servo motor controller, available in incremental or absolute encoder compatible types. The LECSA is a pulse input, positioning type for an incremental encoder, and the LECSB is a pulse input type for an absolute encoder. Also available in the series are the LECSC, CC-Link direct input type for an absolute encoder, and the LECSS, SSCNETlll type for an absolute encoder.
SMC's LECYM/U series is an AC servo motor controller, with a 20-bit absolute encoder. The LECYM/U has a power supply voltage of 200 to 230 VAC with a motor capacity of 100W, 200W, and 400W. The Fieldbus protocol used are MECHATROLINK-II and MECHATROLINK III type for an absolute encoder.
