the dc servo motor controller of frequency converter external option is what/when the servo motor controller inverter in the harmonic requirements for electrical equipment using high power environment, or servo motor inverter selecting the regenerative braking unit, or power factor compensation capacitors are installed on power lines and other occasions, there may be a big wave surge current should be equipped with ac reactor. Ac reactor. Inverter ac reactor used to suppress the servo motor controller of higher harmonic and improve power factor of dc servo motor controller, reduce the influence of harmonic on the power grid at the same time, also can prevent grid impact influence on servo motor controller inverter instantaneous power compensation unit. Instantaneous power compensation unit is connected to the dc bus, it can use a large capacity of the capacitor, the instantaneous power failure makes the dc bus voltage can keep more than 2 s. In line with the motor controller side filter. In line with the motor controller side installation filter electromagnetic interference, zero phase reactor can inhibit the line in addition, keep the power line and the distance between the line of control, adopt the shielded cable grounding, according to the regulation requirements, to reduce the 4 M carrier frequencies of the servo motor frequency converter is also the effective measures to eliminate electromagnetic interference. Built-in option part, servo motor controller manufacturers servo motor controller controller external option for servo motor controller inverter control protection or used to improve the performance of certain aspects of the device, user can configure in principle, but also can be provided by the company of form a complete set; Dc servo motor controller built-in option installed directly in the frequency converter, servo motor controller need to choose the company matching products. http://www。 tcmotor。 Com foshan electrical and mechanical equipment co. , LTD. , brushless motor controller, brushless dc motor controller, dc servo motor controller, planetary reducer, brushless drive, electrical and mechanical, foshan electrical and mechanical equipment co. , LTD
