The blade speed is maintained constant by a variable frequency motor powering the spindle motor. The operator selects the blade speed from 3 to 85 RPM, which is maintained by the variable frequency drive. The feed rate is the variable that is controlled by the PLC, by which the load current of the spindle motor is maintained relatively constant.
