Hi, i recently ordered two 2x200A roboclaw controllers, installed them on our 36V (8KWh battery capacity) robots, and after a few days of successful operation, they both stop enumerating on the USB bus, and have *no* status LEDs illuminated.
We have experience with about 8 different brands of DC motor controllers but here is our setup for reference:
- Roboclaw in dual channel configuration is connected to 36V SLA battery bank
- Marine grade disconnect switch on the positive line
- USB in packet serial mode used for control, from a raspberry PI
The controllers where "verified" by using the Ion Control studio windows app, verified current limit set to 2x200, then installed on our robots (dual channel configuration, one controller per robot).
We drove around both robots for several days, no issues, using USB in packet serial mode.
As of this morning however, neither controller shows any status indicator lights (verified voltage is still 40V across battery terminals to controller) and no longer enumerates on the USB bus. Robots were indoors, unheated space (about 38 deg F)
There are NO linux kernel logs when we plug in the roboclaw controllers anymore, the controllers are completely dead.
Any hints, suggestions? I tried plugging them in to a windows laptop, powering them using a DC power supply at 30V, and they still do not show up on USB, no status LED present.
Again, they worked fine for several days and they were both idle overnight Thursday, and both worked, before we tried using them Friday (March 8th 2019) in the morning.
our order was BM-2102.
