Abstract
In a method of detecting the health of a motion axis in a radiation system including a motor operable to move a load between a first end and a second end, data on an electrical parameter of the motor is collected as the motor moves in the certain range. At least one indicator of the electrical parameter including a maximum, a minimum, an average, and a standard deviation of the electrical parameter is determined and compared with a provided value or range of values indicative of the health of the axis. The health of the motion axis is determined using the comparison of the at least one indicator and the provided value or range of values.
