Controlling frequency of current from roboclaw 2x7A

Hi I am using the roboclaw 2x7A motor controller to supply a sinusoidal current to two Helmholtz coils. I have been able to command a sinusoid but now I want to control its frequency to measure the frequency response of a system. Currently, I have the following parameters in my code 1) time = np.arr...

Roboclaw motor driver not responding with python after using ionstudio

Hi Recently, I was controlling current in a roboclaw 2x45A motor driver using python script from usb. I was able to command a desired current using simple pwm python script. Later, for basic testing, I opened Ionstudio app and then tried controlling currents which also worked. However, when I switch...

Sinusoidal current control for solenoid

Hello My name is Jackie, I am a student in CMU. I am interested in controlling current in a pair of solenoids, which are facing each other as in a Helmholtz coil setup. The idea is to create a time varying magnetic field in the center of the workspace. I have one roboclaw 2x60A motor driver connecte...
