DEAR FRIENDS and BUSINESS PARTNERS WORLDWIDE,

MANY OF YOU HELP ME WITH DETAILS TO COMPLETE PARTS NEEDED TO TEST INVERTER.

I FINALLY FIX AND REPAIR SIEMENS SIMOVERT 6SV1 LONG INVERTER AFTER ALL HARD WORK INVERTER WORKING WITHOUT ANY PROBLEM.

IT WAS GREAT TROUBLE FINDING PROPER FEMALE X1 CONNECTOR FOR THIS X1 MALE CONNECTOR VISIBLE FROM OUTSIDE OF INVERTER AND MAKE PROPER CABLE AND MAKE SWITCHES FOR CONTROL AND CONNECTING ALL THIS AS IS ON THIS IMAGE FROM INSTRUCTION MANUAL IMAGE FROM METRIC MIND AND BEGGING MANY PEOPLE WORLDWIDE TO HELP FOR INFORMATION TO COMPLETE AND TEST AND REPAIR THIS UNIT.

HERE IS ORIGINAL GOLF A3 CONNECTION DRAWING FROM X1 CONNECTOR

I TRY TO GET INFORMATION FROM DIFFERENT SIEMENS companies and THEY REFUSE TO HELP ME ON ALL LEVELS. Answer was: SIEMENS can not give these documents to me due to legal reasons.

AC drives, inverters, and adjustable frequency drives are all terms that are used to refer to equipment designed to control the speed of an AC motor. The term SIMOVERT is used by SIEMENS to identify a SIMOVERT = SIemens MOtor inVERTer (AC drive).

Due to the special requirements in a vehicle a high power to weight ratio, a good degree of efficiency and a low price are extremely important for the electric drive.

In 1995 Volkswagen launched the Golf CityStromer as a pure electric vehicle developed and manufactured under real serial conditions. Nevertheless, sales volume did not exceed 150 vehicles due to lacking customer acceptance related to higher costs and lower performance compared to conventional cars.

For Siemens systems it is for instance motor-inverter matching parameters, i.e. motor's stator winding parameters and magnetic characteristics are stored in inverter's EEPROM to maximize performance and efficiency working with that particular motor.

The inverter is able to control permanent magnet synchronous electric motor, 20 KW, 27 HP used in VW Golf A3 and asynchronous motor drives with the same hardware. See image of this motor. model 1FV5104-6WS09-Z

See here label data for permanent magnet synchronous electric motor, 20 KW, 27 HP

See here rotor speed sensors inside permanent magnet synchronous electric motor.

Low weight and volume of inverter is reached by water-cooling of the power semiconductors and capacitors.

A good efficiency is obtained with low saturation IGBTs.

It is possible to connect a PC to a serial interface for commissioning, monitoring and diagnostics via interface PCB.

In addition a DC/DC power converter for the 12 V system is integrated in the inverter housing.
