摘要： A dead-time generating circuit includes a first gate for generating a gate signal corresponding to a predetermined cutting width, and a second gate for cutting an input signal to be cut by the gate signal by the predetermined cutting width determined by a user and outputting the result. Therefore, an arbitrary block of a pulse width modulated (PWM) signal (whatever it may be in a logic "high" or "low") applied to the inverter of an AC servo driving circuit can be cut constantly by a predetermined cutting width. Also, the cutting width can be adjusted easily by the user.

摘要： The present invention relates to a resolver excitation signal generating apparatus for supplying a reference excitation signal to a resolver attached to a motor for driving a robot or a computer numerical control machine. When a sine-wave signal is transferred from a signal generator to the resolver, the signal is filtered by a low pass filter, amplified up to the rated voltage by means of a line driver and supplied to the resolver, thereby allowing the position of the motor to be controlled exactly.
