LECSS, AC Servo Motor Driver, SSCNET Protocols

The LECSS drivers are compatible with the Mitsubishi's servo system controller network, or SSCNET.  LECSS-S drives an AC servo motor with an 18-bit absolute encoder and is compatible with SSCNETIII at up to 50 Mbps bidirectional transmission speed.  LECSS-T drives an AC servo motor with a 22-bit absolute encoder, and is compatible with SSCENTIII/H, offering an even higher 150 Mbps bidirectional transmission speed.  LECSS-T also adds the STO safety function, improved noise reduction and C-UL-US listing.  Both driver types offer pushing operations and are capable of sychronous motion in multi-axis applications.
