Brake control power output 0-48 V PWM Phase D ***

* These values can be achieved with a motor that is typical for robotic applications, reaching its

maximum power at 60% of its RPM maximum.

This case is used as a realistic assumption to specify the datasheet value for power. Beyond that, the

servo drive itself is able to provide higher power, as it is able to drive its maximum voltage and its

maximum current at the same time.

In reality, no motor can consume both maximum values at the same time, so there is no operating point

of the overall system (motor + drive) that would actually use the theoretical maximum power of the drive.

As the calculation bases on a reference motor, there are setups with large motors that are able to even

exceed the values shown here.

The maximum continuous output power and phase currents are highly dependent on the cooling

situation. Please refer to our Thermal mounting considerations for details.

** The operating voltage is 12-48 V DC. The maximum supply voltage is only for buffering peaks when

braking. The minimum voltage is for configuration purposes only. Please refer to our power supply

instructions for details.

*** This is a fourth phase that can also be used for other purposes (see Manually controlling phase D

voltage) it has a maximum current of 10 A.

1.3 Installation Guide

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

running.

Attention

When dealing with electronic devices, always consider

these handling instructions!

Important

For proper functionality of the current sensors the servo drive must not be exposed to external

magnetic fields, see our

mounting instructions

for details.

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

noticeable 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.

1.3.1.2.1.1 Notes about choosing the supply voltage

The indicated minimal supply voltage of 8 V is enough to power on the servo drive for configuration but

for turning a motor, a voltage above 12 V is required.

Note

Due to voltage drop from power supply to the servo drive is it not recommended to supply the servo

drive at absolute minimal voltages. If your system does not run at 12 V, increasing this value slightly

may be necessary.

1.3.1.2.1.2 Using a PELV or SELV power supply

It’s recommended 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.

Hardware Manuals / SOMANET Node / SOMANET Node rev. E.1

1.3.1.2.1.3 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

do not use contactors behind the power

supply

since the transient-voltage-suppression diodes could get damaged due to the power-up

voltage increase (Surge). This is likely to happen when the power up occurs fast and

can lead to

complete failure

of your servo drive.

If contactors behind the power supply are used, it’s necessary to

include an uni-directional TVS

diode type 1.5KE62A-E3/54

* between Main Power Supply and Ground of the terminal.

* this model has been successfully tested by Synapticon. Other products with the same

specifications may also be appropriate but can’t be recommended.

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.

Hardware Manuals / SOMANET Node / SOMANET Node rev. E.1

1.3.1.2.2 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.

Important

Please make sure the servo drive is properly grounded. You can connect the heatsink to ground.
