SMPS Option
This option describes a topology with a main power without regeneration, but with limited
Braking capabilities dependent on additional capacitance.
The C
external
can be mounted on the Integration Board if there are no space limitations.
Minimum capacitance of the Power supply:
C
external
> “Drive’s Rated Current” *20uF
Figure 17: SMPS Option: Separate VP and VL Power Supplies Connection Diagram
The (+) of the control power supply is connected to the VL+ terminal, while the (-) of the control
power supply is connected directly to the (-) of the DC bus power supply. This connection avoids
high current ground loops due to poor wiring (Figure 17).
