3.2.2 Swap Behavior of the Inverter

Swap behavior of the inverter

The SINAMICS G120 inverter comprises of Power Modules (PM) and Control Units (CU)

Both, PM and CU, can be replaced e.g. to change a defective component. The exchange of

either a PM or a CU is called a "swap".

The following swaps are possible:

• PM hotswap with powered CU (CU is powered via external 24 V source)

• CU swap

• PM swap, including a CU power cycle

Note

A standard CU will not accept a parameter set from a CU with fail-safe functions and vice

versa.
