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.
- Compatible motors (W): 100/200/400
- Power supply voltage (VAC, 50/60Hz): 100~120V no longer available; 200~230 (LECSS-S); 200~240 (LECSS-T)
- Display and settings buttons for direct input and status monitoring
- LEC-MRC2 Configuration software required (sold separately)
- C-UL-US listed (LECSS2-T only)
