Status and Error LEDs
The MCP motor controller has three LEDs for in eld diagnostic. Two status LEDs labeled STAT1 and STAT2 and an error LED labeled
ERR. When the motor controller is rst powered on all 3 LEDs should ash briey to indicate all LEDs are functional. The LEDs will
behave differently depending on the mode. During normal operation the status 1 LED will remain on continuously or blink when data
is received in RC Mode or Serial Modes. The status 2 LED will light when either drive stage is active.
Error and Warning States
When an error occurs both motor channel outputs will be disabled and RoboClaw will stop any further actions until the unit is reset,
or in the case of non-latching E-Stops, the error state is cleared. When warnings occur both motor channel outputs will be controlled
automatically depending on the warning condition(s).

temperature.
Error LED blinks once with
short delay. Other LEDs off.
Over 100°C Temperature Error Motors freewheel while condition exist.
Error LED lit while condition
is active.
Over Current Warning Motor power is automatically limited.
Error LED blinking twice.
STAT1 or STAT2 indicates
channel.
