Logix 1-7
1756-M08SE 8-Axis SERCOS Interface Servo Module
The 1756-M08SE ICP 8-Axis SERCOS interface module provides a fiber-optic
link between the ControlLogix platform and servo drives. The
communication link between the module and the drive(s) is via IEC 61491
and EN-61491 Serial Real-time Communication System (SERCOS) using a
fiber-optic medium. This fiber-optic medium ensures reliable high-speed
data transmission with excellent noise immunity, improved communication
speed, and interconnect wiring between the drive and motion module.
The SERCOS interface module features:
• Drive and motor setup and configuration using RSLogix 5000 software.
• Real-time optical serial interface from ControlLogix to 1394 SERCOS interface systems and Ultra3000
drives for parameter updates.
• Support for eight servo drive axes for greater application flexibility.
• Support for up to 32 meters of plastic fiber-optic cable and 200 meters of glass fiber-optic cable for
distributed, convenient drive support and an overall reduction of wiring.
• Support for high-resolution motor position feedback for superior performance.
• Support for single- and multi-turn absolute feedback for elimination of costly downtime and homing as
a result of power outages.
