摘要： A method is provided for detecting a stall condition in a stepping motor. The stepping motor has two coils and a rotor, and is micro-stepped by substantially continuously driving both of the two coils with out-of-phase time varying voltages. The method includes stepping the stepping motor to a next micro-step. It is then determined when a predetermined motor parameter of a first coil of the two coils is to be sampled. To sample the predetermined motor parameter of, for example, the first coil, the first coil is opened for a predetermined period, wherein the predetermined period is less than or equal to a micro-step. Then the first coil is sampled during the predetermined period and the result of sampling is integrated and used to increment or decrement an accumulated value. If the accumulated value is less than a preset value, then a stall condition exists.

摘要： Stepped rotary motion is imparted to the rotor of a stepping motor by alternately driving at least first and second coils which interact with a plurality of magnetic poles on the rotor. When each of the coils transitions from a driven to a non-driven state, the continued motion of the rotor causes a back electro-motive force to be generated in the coil. The electro-motive forces produced by the coils are rectified, integrated, and then compared with a threshold to determine if a motor stall condition exists.

摘要： The arrangement and method for sputtering material onto a workpiece and cleaning a target of the sputtering chamber includes exposing a target to an electromagnetic field of a strength sufficient to remove particles from the target. The electromagnetic field is generated by an electromagnetic device that is positioned in proximity to the target and generates a strength greater than a strength of a cathode magnetic field behind the target to safely remove the contaminating particulates from the target, which may be made of a strong magnetic material.

摘要： A system and methods are provided for calibrating timing in a remote device to timing in a source device. The source device dictates timing signals to be generated in the remote device. A calibration routine is processed to calibrate timing in the remote device to timing in the source device. The source device provides a reference signal that dictates a period of time to the remote device. The remote device tracks a number of local clock cycles generated for the duration of the dictated period of time. The remote device then establishes a time base for translating a number of clock cycles dictated by the source device to a number of clock cycles generated within the remote device.
