Re: Need help for basic RoboClaw 2x30A wirings.

1. I do recommend going with 12awg but if the wires is short the 13awg will probably be fine. To tell if there is a problem see if the wire is getting warm. If it gets too warm(eg hot) then you need a larger wire). 2. The motor wire should be fine though I would probably go 14awg. 14awg and 12awg is...

Re: Fail to update the firmware and connection lost

1. make sure you power the board from the main power conntions. USB will NOT power the board properly. USB power is only used to detect the connection and only some parasitic power may bleed through. 2. Power cycle the board. 3. Check Windows Device manager to see fi the Roboclaw shows up under Port...

Re: Save custom settings to EEPROM

100,000 cycles(at 85C) is the rated write cycles for each location. If you are running over 85C alot you will need to take that into account. The eeprom is rated for 30,000 cycles at 105C.

Re: Connecting Roboclaw controller to myRIO

You need to install the Windows USB driver as well. Then you need to write VIs to talk to the Roboclaw or use the LabView device interface we wrote. But you will probably need to modify our interface for the MyRio.

Re: Equivalent command for CL HIL Write in Roboclaw

I found this: http://quanser-update.azurewebsites.net ... _read.html

It appears CL HIL is a group of VI commands, not a single command.

Re: Need help for basic RoboClaw 2x30A wirings.

If you are not planning on using encoders you should be able to run all 4 motors from one Roboclaw 2x30. You will connect two motors in parrelel to each motor channel. 1 to 3 Looks fine 4. Yes 5. The different wiring diagrams are simplified. A fuse and diode across the fuse with an optional power sw...

Re: Motor command to be used to just accelerate the motor

I beleive it is the right way. You are effectively building your own PID externally) and only need to control power through the Roboclaw. Yes, constant current in a DC motor effectively translates to constant force however you dont need to control corrent in your application. Controlling current wil...

Re: Motor command to be used to just accelerate the motor

You just have to think about the duty re: force differently. If you want zero force, you need to stop changing the duty, not zero the duty. If you want more forward force you increase duty from where it is at and if you want less force or reverse force you decrease duty. You will need to deal with p...

Re: Clearing homing status manually

Even fi you dont have a motor on the second channel you can send a command to "move" the motor. The homing signal will clear if you move the motor channel forward and release the signal input.

Re: Voltage clamp circuit connection

For MCP boards there are two options. Use a DOUT pin directly connected through a power resistor(2 to 10ohms 50watts or more) to B+. This will work for disipation upto 3.5 amps per DOUT pin. Second option is using an external mosfet(like the one we recommend for Roboclaw voltage clamp circuits). The...
