Re: Concerns over circuit protection with 2x160 34VDC Roboclaw

HAHAHA
I only bought about 3 extra crimps per holes on the connector so I do hope I can get it right the first time.
I'm glad to hear that my approach on safety will make us better off, in the event that something can go wrong.
Just gotta remember steady hands, steady hands, steady hands!

Re: Concerns over circuit protection with 2x160 34VDC Roboclaw

Well at most we only want to see right below the stall current of the motors, which combined is 320A. So your assessment of about 300A being the blowing point of the fuse is spot on. We don't expect to reach that level of current though. I suspect we will see around 40-60A continuous current, even o...

Re: Concerns over circuit protection with 2x160 34VDC Roboclaw

The application in question is a robot for competition. The robot will have to drive around for 5-10 minutes at a time between it's rounds. The robot itself will be just under 140lbs, so it's quite the load.

Re: Concerns over circuit protection with 2x160 34VDC Roboclaw

I'm glad to hear that I'm on the right track with picking out these components.
I'll be sure to make a user-project post once it's all done.

Thanks for the quick response!

Concerns over circuit protection with 2x160 34VDC Roboclaw

Hello All, I'm inquiring as to recommendations on the fuse, power diode and pre-charged resistor for this circuit. I'd be using the 2x160A 34VDC Roboclaw Motor Controller UPDATED CIRCUIT SCHEMATIC Circuit.PNG Motor Specs: MMP D40-675C-24V GP81-014 Rated DC Voltage -> 24VDC Rated Continuous Current -...

Re: Multi-Mode Packet Serial

Thank you for the quick response! It turns out that I mistakenly set up the same serial pins on the Arduino to both Roboclaws, in this case I was using pins 16 (Tx2) and 17(Rx2) on the Mega which were then jumped to a breadboard and I sent lines in parallel to the switch 1 and switch 2 for both robo...

Multi-Mode Packet Serial

List of parts: Two roboclaw 2x30A in multi-mode packet serial. Arduino Mega as the MCU. 2 32 RPM Premium Planetary Gear Motors with Encoders. Using a 12 V 30 A DC power supply in voltage clamp setting. I'm having trouble getting the multi-mode to work correctly. My arduino code runs with one robocla...
