    How to get the firmware from a MR-J2S-B servo amplifier?

    Hi,
    I have several bad MR-J2S-B servo amplifers and I do not really want to give up them. I judge the trouble reason is that the firmware of main controller---SH7065 had been lost. Fortunately, I have some good amplifers in hand with the same model. Can I get the firmware from a good one and re-programme those bad? or where can I downlaod the firmware I need?
    Please help!

    Thanks and Regards,
    greatwall2

    you can reflash them with SHflash.exe utility which comes with SETUP161E. when it asks to set the boot mode short pins 5-6 of the CON6 connector and switch on the power. the 7-seg LED display should stay blank. PM me with you email and i will send you a firmware image.

    aha, i see.

    it is possible to do if:
    1. you have a working MR-J2S-350A-S011 drive to read the firmware from.
    2. your standard MR-J2S-350A has a FLASH CPU. see http://yurtaev.com/mr-j-faq.html

    drop me an email at the above link, i will send you a utility which can read the firmware. you'll need a windows pc with MR-CPCATCBL serial cable (the same used for MR Configurator)

    if the firmware can be read, i will convert it fo intel hex format which can be used with SHFlash utility to flash the new drive

    also, you need to read all 255 parameters from the -S011 drive using MR Configurator. to do it, set param No.19 to "ABCD", reboot the drive, read params and save em to a file

    Thank you very much for your reply.
    I have read this article before, but I don't know how to operate the process.
    I will read correctly about the parameters.
    But can you tell me the correct read firmware process?
    And how to write the firmware process correctly?
    You are my savior

    Hello sir,
    I have the same problem with MR-J2S-70B.
    I need to unload firmware and parameters from the old and load it to the new servo amplifier.
    Is it possible that another firmware version in the same servo amplifier won´t work with CPU controller correctly?

    Thank you
