Abstract

PURPOSE:To prevent occurrence of regeneration from an electric motor to a transducer, by making frequency varying rate commanding execute compensating action to such an effect as to enable current flow to be supplied from the transducer to the electric motor at all times. CONSTITUTION:An inclination signal generator 10's output V14 as a voltage commanding signal and a voltage sensor 9's output as a real value signal are put into a voltage controller 6, and the output Vc is put into a current controller 5, as a current commanding signal, together with the real value signal from a current sensor 8. Further, by providing an inclination control signal generator 11 which detects direction of the transducer's power and also detects an extremely small variation immediately before a converter 1's output current command Vc becomes zero and amplifies it, the output V15 is subtractively added to an original frequency varying rate command V13 as an additional frequency varying rate command. It is possible, by doing so, to control the frequency varying rate command and also to prevent the transducer from shifting to regeneration mode.
