1.2 Wiring instructions

The motor and power cables must be twisted for EMC reasons.

Note

SOMANET servo drives are densely packed with high-performance components. Even at

idle/torque off, several components such as power supplies, cause the servo drive to get warm,

especially when it’s not connected to any heat conducting structure. The servo drives’ 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.

1.2.1 Using a PELV or SELV power supply

It’s recommanded to use a protected extra-low voltage supply (PELV) instead of a safety extra-low

voltage supply (SELV).

If a SELV is used, it’s possible that the isolation from the earth can be violated through our drive (e.g.

through heatsink or mechanical mountings) and the supply becomes PELV.



1.2.2 Warning about using contactors behind the power

supply

Attention

Our servo drives are designed for voltages between 12 V and 48 V (60 V Max), they should be

run with an appropriate extra-low voltage supply. Please

In case you are running several servo drives behind a contactor, please use an uni-directional TVS

diode on each drive because of the inductances of the wiring.

1.4 Grounding and connecting a brake

Please make sure you ground the board properly.

Your configuration will look like this:

In case you have additional Logic Supply, please wire your module like this:

Hardware Manuals / SOMANET Node / SOMANET Node rev.

D.3/D.4 / Installation Guide

1.4.1 Connecting a Brake

If your system has an attached brake, please connect the brake cables to Phase D and Ground. These

two threads should be twisted together or at least be paired to have a minimum area between them.

By default, Logic Supply is deactivated, it is therefore recommended to use Logic Ground (pin 7 of the

Main Supply Connector) for the brake.

If Logic Supply is active, Ground of the brake can be connected to the Ground cable of the 48V power

supply in a spot close to the board or it can be connected together with the Ground of the 48V supply

to the pin 5 of the Main Supply connector if they fit in there.

For mounting please refer to our mounting instructions:

Hardware Manuals / SOMANET Node / SOMANET Node rev.

D.3/D.4 / Installation Guide

1.5 Mounting instructions

1.5.1 Heat dissipation

For correct functioning, the servo drive must be installed on a sufficiantly dimensioned heat

conducting surface made of a suitable material, such as aluminum.

Ensure that the servo drive is screwed properly to the heat conducting surface to facilitate the heat

transfer.

1.5.2 Dimensions

Hardware Manuals / SOMANET Node / SOMANET Node rev.

D.3/D.4 / Installation Guide

Note

Please ensure to use as much of the available thread length as possible for tightening the Node to

prevent damage to the thread.

1.5.3 Interference with magnetic fields

Please consider the placement of the servo drive carefully when designing the motion control

application. It has become evident that the motor’s magnetic field has an impact on the drive’s

performance.

These are the preferred arrangements:

1. At any position but shielded with a Faraday’s cage

2. Behind the motor

3. Beside the motor but shielded from the motor’s magnetic field with a plate consisting of a magnetic

shielding material such as steel or Mu-Metal.

That’s it! The next step is commissioning and tuning your drive:
