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.
