Brake current too low for A4, A5 and A6

    hi guys,

    I'm working with KRC5 and KR16 R1610-2 robot on the field for 3 days.

    Today, I got a strange error after power cut. It says "Ackn error: Brake current too low (KSP-600-6S)" for A4, A5 and A6.

    I can't move the robot because of this problem.

    I checked the ground cable between the robot and controller. It seems it's ok.

    I checked the power on the automation board and the power on the robot. They all seems fine.

    I searched it on the web but can't find a solution yet.

    Is there anyone who can help me about it?

    Thanks all

    Hello GoodFellas41,

    Did you happen to find a resolution to this problem? I just encountered the same problem. I called KUKA support and we were able to find the cause in our case. We believe for ours that an internal cable inside the base of the robot must be missing, unplugged, or damaged. We are working with a KUKA tech to replace the cable.

    Along the way, we checked the XD 20.1 and XD 202.2 connections on the KRC5 Micro to make sure they were securely plugged in. If they are not properly plugged in, this issue can happen. KUKA suggests zip tying these cables in place to provide some strain relief. We also checked the X30 connector on the base of the robot to make sure it was securely plugged in.

    Hey SethFreemanSISU,

    Yeah, i solved this problem long time ago. I don't know why I did get this problem but here's how you can solve it,

    1. Try to unplugg and plug again the motor cables.

    2. Unmaster A4,A5 and A6 and master them again.

    3. Check the power source.

    One of these 3 ways need to help you.

    Some of the connectors can be difficult at times. my pet peeve is the Yellock type as used for robot motors on KRC4 compact. just wheel training cell from one room into another and one is likely to have a problem so - better reseat the X20/X30 connectors.

    others too could need reconnecting, btw. motor brakes tend to be bunched together meaning that single poor contact in the brake circuit can affect multiple axes.
