KAWASAKI D controller Error D1512

    Yes, I suppose it's worth swapping the 1GM to eliminate that.

    D2026 is the usual error produced for a mismatched 1GM board during bootup

    The fault is more likely to be the actual 1KB/1RB though.

    Maybe worth inspecting the battery, but I doubt this to be the root cause.

    Electronic components do not have infinite life and often can fail.

    You have an old system possibly >10 years so electronic 'parkinsons/alzheimers' can set in.

    Capacitors drift/transistors internal gains start to drift and not until you power cycle, do these symptoms reveal themselves.

    TV's, PC's, washing machines.....anything can suddenly stop working for no other reason but component failure....it happens.

    The document attached by you is very useful. According to this I can conclude that the 1KB / 1RB board is defective.

    Do you have any idea what the difference is between the two 1KB / 1RB boards, the first one has the yellow tabs and the second one has the red tabs. These tabs can be seen in the attached picture.

    Another difference exists between the identification codes 50999-2824R00 the one with the yellow tabs and 50999-2824R11 the one with the red tabs.

    Thank you!

    Regards.

    2 Versions of D Controller exist.

    1. D: Uses 1KA and 1KB (Red Tabs) - Initial D Controller

    2. D+: Uses 1RA and 1RB (Yellow Tabs) - Additional version increased accuracy, velocity and processing.

    Red and Yellow tab boards cannot be mixed.

    AS and SV software versions are different between D and D+ Controllers.

    D+ Controllers had increased base memory (I think).

    I think from memory D+ Controllers had Ethernet port as standard, whereas D Controller was optional.

    Hi everyone,

    I have the D1590 error and I can not move the robot. I can't turn on the motor. The manual says that it could be produced for:

    1.-A drop in the AC primary power voltage or shut-off of the breaker

    2.-Failure of the power/6-axis amplifier board

    3.-Failure of the servo board

    4.-Failure of the power sequence board

    The recommended measures are:

    1.-Check to make sure that the AC primary power voltage has not dropped or is not shut off.

    2.-Replace the power/6-axis amplifier board.

    3.-Replace the servo board.

    4.-Replace the power sequence board.

    Does anyone know why that could happened?

    Or does anyone know a less generic solution?

    Thank you very much.

    Welcome to the forum........... :beerchug:

    Please create a new thread in future as this error is not related to this thread at all.

    There is no error, that error is produced each time you power cycle the controller.

    - Check the date and timestamp, it will tie in with you power cycling.

    The reason you cannot get motor power is that there is an active emergency stop - seen in red on the right side of the teach pendant screenshot.

    - Check Teach Pendant.

    - Check Operation Panel.

    - Check External emergency stops wired into connector X7 on 1KP board.

    Hi kwakisaki,

    Thank you for your answer. Sorry I'm new in Kawasaki and I thought that the D1512 and the D1590 might be relationated.

    I have checked all that you said and the error continues.

    By the way, I have opened a thread to talk about it.
