Roboclaw 2X7A

Hi everyone,

I am currently testing a Roboclaw 2x7A motion controller and am having an error message, expressed by the LEDs and the ION Motion PC software, which states that I have an “M1 Driver Fault”. Before getting in the explanation, I want to say that I power all of the setup from an old PC power supply at 12V 15A. Here is what happened:

  1. I was driving using output 1 and everything went fine for ~ 10 seconds.
    1.5. I could hear a buzzing coming from the Roboclaw
    1.75. The screen monitor connected on the same outlet as the PC power supply started flickering.

  2. I turn everything off as I notice something is wrong.

  3. I can smell the fume of burnt electronic components coming from the Roboclaw.

  4. If powered again, the controller returns M1 Driver Fault error message and will not let me use M2 output which is I assume a safety feature not doccumented in the manual (???).

I can see a burnt 88537N N-channel mosfet IC on the PCB (the one associated to Output 1, the closest to the PCB edge.).

I am therefore wondering:

  1. Is the 88537N IC likely the only damaged component ? (upon visual inspection it is the only one with the distinctive bubble on it)
    Or have the damages spread along the board and damaged components common to both channels ? Which would explain why I can’t use Output 2.
  2. Do Robotshop (Montreal) happen to have any 88537N IC, normally used for repairs, that could be shipped along with my next Roboclaw order ?

Best regards,

pFortin

Hi,

]As we understand, you are powering a screen monitor from the same power supply that you power your motor with. Is that correct ? If so, what is its power consumption ratings ? (screen monitor) /:m]
]What are the electrical specifications of the DC Motor you are driving ? (current consumption)/:m]
]Did you try to remove your screen monitor and power only the Roboclaw+DC Motor ?/:m]We can’t know if other components have been damaged on the Roboclaw. In this case, we suggest you to contact directly the manufacturer here.
At this time, we unfortunately don’t have the 88537N IC.

Regards,
