Introduction Environmentals and Certifications SERCOS Interface Example Configurations
SERCOS Interface

The 1768-L4x and -L4xS controllers support integrated motion. You can communicate directly to a servo drive using a motion interface or over a network.

With this controller You can have
1768-L43
1768-L43S
• Four axis
• Two feedback axis
• Six virtual axis
1768-L45
1768-L45S
• Eight axis
• Four feedback axis
• Six virtual axis
  

The SERCOS interface modules can connect to these servo drives.
