10.1 Interlocking Power Supply Unit and
DC-AC Servo Drives
The following example shows how the Power Supply Unit can be connected to the
DC-AC Servo Drives used in the multi-axis system such that the entire multi-axis system
is shut down in the event of a fault.
In the normal case the DC-AC Servo Drives feed power back to the mains via the Power
Supply Unit in regenerative operation. On the failure of the Power Supply Unit or the
mains, the energy is fed to the braking resistor. To protect against overloading the Power
Supply Unit's brake chopper, the Power Supply Unit can be connected to the DC-AC
Servo Drives and configu ed as follows. As soon as the Power Supply Unit is no longer
actively regulated, the enable for the power stage (ENPO) is withdrawn from the
DC-AC Servo Drives.
Connect the Power Supply Unit to the DC-AC Servo Drives connected as shown in Figure 10.1.
Assign the output REL (X4/23,24) on the Power Supply Unit the function "Regulation in operation"
(value 2, OUTPUT_FS_ACTIV).
You will find further functions in the Operation Manual MSD Power Supply Unit.
