Re: E Stop with Packetized Serial on Arduino

I would recommend retrying the command if it failes at least some number of times. The Roboclaw arduino library currentl will only retry the command 3 times internally before giving up and I beleive the pythin library leaves retries up to the user altogether. In the situation where you are unable to...

Re: Wire size and motor type

Yes. Twisting the power wires will reduce the inductance of the wire. However long runs of wires will still have a fairly high inductance. I would recommend testing(carefully) to see if the length you need to run will work peroperly.

Re: Buffered drive

1. No, there is no way to get the actual command that is executing. You have to keep track of what commands you buffered and then you can use the current number from the GetBuffers command to determine what command is executing. 2. Yes. non-buffered commands will immediately clear that motors buffer...

Re: What's the best command to free-wheel?

Just to be clear the Save Settings command is called "WriteNVM".

Re: Roboclaw takes too long to execute movement commands / packet serial over USB

Please be more specific about the "driver is telling me there is a problem". If the roboclaw is communicating(even just some times) you probably have it wired correctly. S1 is the receive pin and S2 is the transmit pin. The roboclaw requires TTL serial signals(0 to 5v max). If oyu are conn...

Re: E Stop with Packetized Serial on Arduino

The E-STOP and HOME signals are active low(eg pull the pin low to e-stop/home). However e-stop is not really appropriate for you since you want to home the motors after an error. If you mean an error in the roboclaw you shouldnt be moving the motors after a Roboclaw error(Roboclaw errors are only ov...

Re: Wire size and motor type

Motors are already high inductance so inductance in the wires to them usually isnt a problem. In your situtation running the motor wires the full length would be best and keep the battery right next to the controller. As for the cutoff just run a e-stop switch form the S3 pin(set the pin to e-stop m...

Re: Powering RoboClaw from boost converter

can should have been can't If the regen isnt sunk by the regen accu the voltage will start to rise instead. When using systems that cant sink the regen current(eg power supplies) you usually need to burn the energy off with an active switch to engage a large wattage resistor across B+-. Storing the ...

Re: What's the best command to free-wheel?

No. Only to ram. EEPROM is only written when you specifically send a Save Settings command.

Re: Wire size and motor type

1. 8 awg will fit and in a pinch you can get 6 awg to fit. 2. Inductance in the wire. If the inductance is high enough it takes a long time(relatively speaking) for current to rise and fall. When that happens you will get wild swings in voltage which will cause excesive current ripple on the large f...
