	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... 3D models for Sabertooth IGS files are available for Sabertooth 2x32 and 2x60 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 interference... 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 with component values 10k ohms and at least .1uf is recommended, as shown in the attached fi... 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 un-powered. The current generated when the motors spin could have the potential to harm the Sabertooth or SyRen motor driver. To allev... Battery size for Sabertooth dual motor drivers Minimum battery capacity (amp hours) recommendations are as follows:   2x12RC:  5000mAh (typical, 8000mAh) 2x32:  20Ah (typical, 35-55Ah) 2x60:  35Ah (typical, 85Ah)     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... 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, ... DEScribe connection issues A few points if you're having trouble connecting to DEScribe. Be sure to allow sufficient time for drivers to install (if applicable) when a new product is connected via USB. The Sabertooth, Syren or... 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 ... 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.
