ATTENTION! With high currents flowing through the ground terminals a high
resistance isolation from the device ground is required. This may cause incor-
rect response of the drive (avoid ring currents in the wiring).
NOTE: Note that in the event of a fault the supply unit may no longer be able
to feed regenerative power from the DC-AC servo drives back into the grid.
In order to prevent destruction of the supply unit braking resistor in sustained
regenerative mode, the DC-AC servo drives and power supply unit can be
mutually locked via X4. For more information and an example of circuit con-
figuration refer to appendix on page 83.
