This paper proposes a new method of multi-axle control for numerical controller. By adopting this method, pulse series for real-time control can be easily generated, and driving velocity for multi-axle with the non-orthogonal coordinate also can be easily realize. Command pulse can be modified in real time by introducing the sensor signal into the feedback loop of controller. Simulation of six joints...
This paper proposes a new algorithm of generating command pulses for numerical controller. Different from the presently used NC pulse generating method, pulse train with automatically changed frequency following reference displacement commands can be generated using the proposed algorithm, and the generated command pulses can be modified in real time according to the reference signal. Moreover, by...
This paper proposes a numerical controller with a new algorithm for V-F transformation. Unlike the existing models which operate with a fixed frequency, the proposed controller could generate pulse series with arbitrary intervals so that the velocity of the motor can be changed in real time according to requirements. Moreover, the error of the controller can be compensated by employing a feedforward...
The BIA has now 15 years of experience with the certification of complex electronic systems for safety-related applications in the machinery sector. Using the example of machining centres, this presentation will show the systematic procedure for verifying and validating control systems using Application Specific Integrated Circuits (ASICs) and microcomputers for safety functions. One section will...
