2.1.3 Multi-axis
drive
In the case of multi-axis drives (see Fig. 2-3 on page 2-4) with more
than 3 axes, several inverters are connected to the line voltage via a
common rectifier unit.
An external power supply is required for the 24 V supply voltage for the
inverter electronics.
The regenerative energy originating in one axis can be used by the
other motors, stored in the capacitor module or dissipated in the
braking resistor.
