	Basic Troubleshooting for Motor Drivers STATUS LED is not coming on. Make sure you have at least the minimum input voltage specified for the motor driver at the driver's B+/B- terminals. If minimum voltage is present, there may be a problem... Which motor driver works best with wheelchair motors? Wheelchair motors require sufficient terminal blocks to hold the wiring safely. For this reason, we do NOT recommend using the following drivers with wheelchair motors: Sabertooth 2x5RC, 2x5, 2x12RC, ... Kangaroo Tuning Using DEScribe Software To tune Kangaroo using DEscribe software: Go to the DEscribe "Help" menu for wiring instructions. Click on the "Connect and Download Settings" button. Click "Detect" so the softwa Kangaroo Tuning with Radio Control or Analog Joystick If you're not able to manually push your robot for tuning, these are the steps for "unlocking" Drive Mode to use an RC transmitter or analog joystick for open-loop control:   1- Press and hold the Kan... Kangaroo "Wiring Error," or "No feedback detected" & Limit Switch errors The most common error while tuning the Kangaroo is "wiring error" (one flash of the LED), or "No Feedback Detected" (when using DEscribe). Encoder signals are very susceptible to noise or interferenc... 3D models for Sabertooth IGS files are available for Sabertooth 2x32 and 2x60 Filtered PWM in Analog Mode If you are using a filtered PWM signal from a microcontroller to generate the analog voltage, an R/C filter Do I need a fuse between the battery connection and the Sabertooth/Syren? If this is more of a hobby project instead of an industrial product, most people do not use fuses. The Sabertooth has built-in current limiting. We prefer that you fuse the motors rather than the batt... What to do with regenerative current while driver is un-powered but the motors are turned Sometimes you will want to move your robot or vehicle while it is unpowered. The current generated when the motors spin could have the potential to harm the Sabertooth or SyRen motor driver. To allevi... Disable R/C autocalibration without turning off the signal timeout on a Sabertooth? Sabertooth motor drivers (excepting RC-only versions) require a software setting to use a fixed RC servo range along with the timeout/failsafe feature. Go to the RC page in DEScribe and check "Use cus... Using 4 pole motors with Sabertooth/SyRen 4 pole motors are compatible with our motor drivers if installed properly. You will need a standard 60-100V, 3A diode for each motor. See attached wiring diagram. Wheelchair Brake Wiring Wheelchair brakes are directly compatible with Sabertooth 2x32 when wired properly (see 2x32 datasheet for details and software setup). Using brakes with all other Sabertooth and Syren motor drivers r... Jerky movement or noisy feedback when using Kangaroo w/ actuators Feedback potentiometers in some linear actuators often produce an unstable signal. This can often be remedied by installing a 10uF capacitor between the signal (A) and ground pins (B), then re-tuning ... Arduino examples for Kangaroo Simplified Serial Arduino examples for Kangaroo Simplified Serial Bricked 2x32, Error On during/after firmware update An interruption of power or communication during a firmware update might cause 2x32 to get stuck in an error state. Power down the 2x32 completely so that the LEDs are off. Then reconnect the USB to D... Battery size for Sabertooth dual motor drivers Minimum battery capacity (amp hours) recommendations are as follows:   2x12RC:  5000mAh 2x25:  18Ah 2x60:  35Ah Maximum wire size for Syren 50? Here is the wire size recommendation for Syren 50.   Signal terminal block (smaller block): 14AWG down to 30AWG Battery/Motor terminal block: The maximum size wire that can be used here is 8AWG.
