The motor and power cables must be twisted for EMC reasons.
No reverse polarity protection! Always ensure that the power cables are connected correctly, otherwise the Drive may be damaged beyond repair!
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 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.
Use a protected extra-low voltage (PELV) power supply.
Our servo drives are designed for voltages between 24 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.
If your system has an attached brake, please connect the brake cables to the brake connector. These two threads should be twisted together or at least be paired to have a minimum area between them.
This brake integrates Safe Brake Control functionality (SBC).
Please make sure the servo drive is properly grounded.
