Abstract:
When a power conversion apparatus and safety function unit are integrated, costs of component and development are expensive and the product price increases. A power conversion system includes a power conversion apparatus for driving a motor and a safety function unit for executing a safety function. Upon receiving a safety request signal, the safety function unit outputs a deceleration indication signal to decelerate the motor and outputs a torque-off signal for turning off torque applied to the motor when the motor speed exceeds a predetermined value.
