Warnings
There are several warnings that should be noted before getting started. Damage can easily result
by not properly wiring RoboClaw. Harm can also result by not properly planning emergency
situations. Any time mechanical movement is involved the potential for harm is present. The
following information can help avoid damage to RoboClaw, connected devices and help reduce
the potential for harm or bodily injury.
Disconnecting the negative power terminal is not the proper way to shut down a
motor controller. Any connected I/O to RoboClaw will create a ground loop and
cause damage to RoboClaw and attached devices.
Brushed DC motors are generators when spun. A robot being pushed or coasting can
create enough voltage to power RoboClaws logic intermittenly creating an unsafe
state. Always stop the motors before powering down RoboClaw.
RoboClaw has a minimum power requirement. Under heavy loads, without a logic
battery and, brownouts can happen. This will cause erratic behavior. A logic battery
should be used in these situations.
Never reverse the main battery wires Roboclaw will be permenantly damaged.
Never disconnect the motors from RoboClaw when under power. Damage will result.
