The Application of Frequency Converter in Large Scale Bearing Internal and External Raceway Exceeds Grinding Machine

This paper has introduced two methods of digital control and analog control of the SIEMENS frequency converter,through the application in large scale bearing internal and external raceway exceeds grinding machine,and introduced in detail the two method and actual effect that controls workpiece axle generator rotational speed with the digital control of frequency converter and controls vibration generator rotational speed with analog control of frequency converter.
