Important
The cable length for Main Power Supply (12-48 V) must not exceed 30 m.

* Maximum current carrying capacity: 10 A
Note
** this additional logic supply is not connected by default. It is not required for normal operation.
For additional information, please contact [e-mail]
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.
1.2.1.1 Notes about choosing the supply voltage
The indicated minimal supply voltage of 10 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.

1.2.1.2 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.
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.

1.2.2 Connecting a Brake
Attention
When using a safe brake in combination with Node Safety, use SBC Out instead of Phase D.
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.

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