Basic Troubleshooting for Motor Drivers Article rated 3.3/5.0
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...
Do I need a fuse between the battery connection and the Sabertooth/Syren? Article rated 3.4/5.0
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 Article rated 3.4/5.0
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...
Wheelchair Brake Wiring Article rated 3.9/5.0
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...
How do I disable R/C autocalibration without turning off the signal timeout on a Sabertooth? Article rated 3.0/5.0
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 Article rated 3.0/5.0
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.
Kangaroo Tuning with Radio Control or Analog Joystick Article rated 3.0/5.0
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 Tuning Using DEScribe Software Article rated 3.4/5.0
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 "Wiring Error," or "No feedback detected" & Limit Switch errors Article rated 3.4/5.0
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...
Jerky movement or noisy feedback when using Kangaroo w/ actuators Article rated 3.4/5.0
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 Article rated 3.0/5.0
Arduino examples for Kangaroo Simplified Serial
3D models for Sabertooth 2x32 and 2x60 Article rated 3.0/5.0
3D models for Sabertooth 2x32 and 2x60
Filtered PWM in Analog Mode Article rated 3.4/5.0
If you are using a filtered PWM signal from a microcontroller to generate the analog voltage, an R/C filter
Bricked 2x32, Error On during/after firmware update Article rated 3.4/5.0
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...
