Servo Node Setup Guide

This setup manual will guide you through the basic steps to get your SOMANET Servo Node 400/1000/2000 EtherCAT running.

Contents of your Evaluation Kit

Open your box and verify that it contains the following:

  • SOMANET Servo Drive node (assembled) consisting of 3 modules: Com EtherCAT, Core C2X and Drive 400/1000/2000

  • Ethernet Cable STP 2 m RJ45 (or PicoBlade) to PicoBlade 5-pin plug

  • IO Cable Kit consisting of:
    • 1 x 8 wire GPIO cable
    • 1 x 12 wire GPIO cable
    • 2 x 10 wire encoder flat cable


For proper functionality of the current sensors the Servo Node must not be exposed to external magnetic fields.

Attaching the cables

Attach your EtherCAT cable (RJ45-to-PicoBlade cable) to your node and to your PC.


Details about EtherCAT Connectors.


The Pin-Out of the Drive module differs depending on the version. Please check the version indicated on top of your Drive module:


Wiring instructions for Drive 1000 Rev. C.4

Wiring instructions for Drive 400/1000 Rev. D.3/D.4

Wiring instructions for Drive 400/1000/2000 Rev. E.1


If your Node is running Bootloader v1.0 you may find the LED fading in rainbow colors indicating that the bootloader is active.

SOMANET Servo Nodes are densely packed with high-performance components. Even at idle/torque off, several components such as power supplies, cause the Node to get hot, especially when it’s not connected to any heat conducting structure. The SOMANET Servo Nodes’ power stages and control algorithms were optimized for efficiency at high power output and actually make them one of the most efficient servo drives available. The heat generation is not linear, which makes it actually more noticable at idle or low power. Please ensure by design of your mounting situation that the heat interface is connected to sufficient structure to appropriately dissipate generated heat.

LED Indicators

SOMANET Servo Nodes have several LEDs showing the state of the node and indicating errors.
