Abstract: Methods and systems for determining operational health of a top drive. A method may include commencing operation of a processing device to determine operational health of a top drive for rotating a drill string at a wellsite. The processing device may then output a first control command to a first motor of the top drive to cause the first motor to perform a rotational operation, output a second control command to a second motor of the top drive to cause the second motor to impart a load to the first motor, receive a sensor measurement indicative of an operational parameter of the top drive, and determine operational health of the top drive based on the sensor measurement.
