    Default Kollmorgen S603

    Does anyone know the circuit design for supplying power to the IGBT driver stages?
    I seem to be missing the power.....I get 0V across the gates of all the stages to and bottom. I was expecting about -5V to -10V. I cannot trace the tracks because of the PCB.
    Has anyone drawn the circuit out......I've tried with limited success!

    HI ! Rich
    I am AMIT PATEL from INDIA running my own workshop ,dealing in component level repairs from last 28 years , now involved Mainly in KOLLMORGEN servo drives repairs. I have handle many such drive in 600 series i.e. 601 , 603 ,606,610 620, 640 & S748.

    About the drive you need to check first whether DC 300+ is getting generated from 3 phase given, next that 300v DC is reaching to IGBT , Enable the drive with all necessary hardware etc. connected , then.... you can run the motor connected. If there is any problem you need to trace U V W circuit problems near IGBT on component level . I can repair it for you or in the extreme case provide you entire drive at a reasonable price.

    I was looking for the same thing all around the web, i have an almost clean PCB board but is still hard to trace connections due to multi layer layout
