10 ADL500 • Quick installation guide - Specifications and connection
The inverter converts the constant frequency and voltage of an existing three-phase network into DC voltage, from
which it obtains a new three-phase network with variable voltage and frequency. With this variable three-phase network
the speed of three-phase asynchronous and synchronous motors can be controlled continuously.
1. Mains supply voltage
2. Mains choke (see chapter "5.2 Input chokes" on page 18).
Converts AC voltage into DC voltage via a three-phase full wave bridge.
4. Intermediate circuit
With pre-load resistor and levelling capacitors DC voltage (U)
5. IGBT inverter bridge
Converts DC voltage into three-phase AC voltage with variable amplitude and frequency
Cards for controlling and regulating the closed and open-loop power section. Commands, references and reactions
are connected to these.
7. Output voltage
Three-phase AC voltage.
8. Speed feedback encoder (see section "7.3.3 Feedback Connection" on page 31).
