Proper installation and operation of the RoboClaw motor controller is critical for both device safety and operator safety. Incorrect wiring can result in permanent damage to the controller and connected equipment. Furthermore, any system involving mechanical movement presents inherent safety risks that require careful consideration of emergency scenarios. Please note the following warnings.
Disconnecting the negative terminal while I/O devices or a USB cable are connected can create ground loops and damage the motor controller or attached devices. Always disconnect the positive lead first when powering down.
Brushed DC motors act as generators when in motion. If a robot is pushed or allowed to coast, the motors can generate sufficient voltage to intermittently power RoboClaw’s logic circuits, creating an unsafe operating state.
RoboClaw requires a stable minimum voltage to operate. Under heavy loads, voltage drops may cause brownouts or erratic behavior. In these situations a separate logic battery is recommended for reliable operation.
Never reverse battery polarity. Doing so will permanently damage the motor controller.
Never disconnect the motors while they are running. Doing so can generate voltage spikes that may damage the motor controller or other connected electronics.
