Decoding the order code

6EW1 — the Siemens order-number group for modular power supply units.

890 — the unit type number within the 6EW1 modular power supply range.

0AB — the execution and version code identifying this build.

G1 — the power supply designation used in the SIMODRIVE 650 AC main-spindle drive documentation.

Host converters

The G1 power supply is the electronics supply for the SIMODRIVE 650 AC main-spindle drive converters 6SC6504-4A, 6SC6506-4A, 6SC6508-4A and 6SC6512-4A. Compatible With: 6SC6504-4A, 6SC6506-4A, 6SC6508-4A, 6SC6512-4A.

What these specs mean in practice

A main-spindle drive keeps its control electronics on a supply that is separate from the power section, so the G1 board is the part that has to be sound before the converter will run up, report status or accept a speed reference at all. Replacing the supply board is the usual route to returning a 6SC65 converter to service without exchanging the whole unit.

Mounting data

Mounting Type: plug-in board mounted inside the SIMODRIVE 650 converter chassis. Form Factor: single printed circuit board assembly.

Quantity and configuration

Unit Quantity: 1 Pc. Board only. Condition: new takeout, tested.

Interchange guidance

Searchable forms of the number: 6EW1890-0AB, 6EW1 890-0AB, 6-EW-1890-0AB and 6EW18900AB. The trailing 0AB execution code is the element to match; sibling boards in the same 6EW1 890 family carry different execution codes and are built for different converter ranges.
