SIMOVERT P (6SE20/21), MICROMASTER, SINAMICS G120 (CU2x0x): Successsor, replacement inverter.

  • Entry
  • Associated product(s)
This FAQ applies only to the SIMOVERT P (6SE20/21), MICROMASTER, SINAMICS G120 (CU2x0x) inverters. Description.

Where can I find a replacement for my old SIMOVERT P, MICROMASTER or SINAMICS G120 (CU2x0x) inverter?

Description
If you want to replace an old inverter with an equivalent one you can use the "DT-Configurator" tool with following link www.siemens.com/dt-configurator .
It is also possible to select an equivalent inverter by using the SIEMENS SIZER tool; Entry-ID: 54992004

For this methode you only need some characteristical data of the old inverter. It is possible to get this data with the PMD Tool (only Siemens internal) or with the following listed characteristical data. As an example the order number 6SE3114-0DC40:

Further information
Today's MICROMASTER 4 as well as SINAMICS G120 (CU2x0x) can, in most cases, be replaced by SINAMICS G120 (CU2x0-2).
SINAMICS G120 (CU2x0-2) onwards are compatible from a functional perspective; however they are not compatible from a spare part perspective – i.e. the parameterization must be appropriately adapted.

Generally, older inverters have an integrated, basic (simple) operator panel. This is no longer the case for newer inverter types. Operator panels and additional accessories can be found in the “Configurator” under the “Accessories” tab.
