Abstract

PURPOSE: To control the power rerunning by setting a limit value of frequency according to the handle position of the master controller and by making the slip frequency zero to stop the notch when the rotation frequency of the induction motor is more than a specified control value of the master controller.
CONSTITUTION: An output signal of the pulse generator 2 that detects the number of rotation of the induction motor 1 is converted by the frequency voltage converter 3. When the value of converted signal exceeds the voltage fp set by the master controller 11 and the notching circuit 16, the comparator 15 provides a positive output, the slip frequency pattern SP is reduced by the subtracter 12. Output of the subtracter is fed to the adder 4 through the limiter 13 and diode 14. Since the output signal of adder is provided to the frequency control block 6 to control the inverter 5, the output frequency of inverter is not made less than the rotation frequency of induction motor during power running, aregenerative state is not produced even in power rerunning after speeding, up, the operation can smoothly be performed.
