Important
The motor and power cables must be twisted for EMC reasons.
Attention
No reverse polarity protection! Always ensure that the power cables are connected correctly, otherwise
the Drive may be damaged beyond repair!
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.
Note
Use a protected extra-low voltage (PELV) power supply.
1.2.2.1.1.1.1 Warning about using contactors behind the power supply
Attention
Our servo drives are designed for voltages between 24 V and 48 V (55 V ; Max,cont 60 V
Max,peak), 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.
