Inovance MDBUN Series Braking Unit User ManualPrefaceThank you for purchasing Inovance MDBUN series braking unit.Inovance MDBUN series braking unit applies to the applications where an AC drive orservo drive (hereinafter referred to as "drive")needs to perfomm deceleration,positioningor braking operation.When the drive performs braking,kinetic energy is converted toelectric energy which is fed back to the drive due to the mechanical inertia of the load.This will cause rising of the DC bus voltage of the drive.Therefore,a braking unit isrequired to ensure normal running of the drive.The regenerative energy is consumed bythe braking resistor,preventing the drive from stopping or even being damaged due toovervoltage protection.Inovance MDBUN series braking unit provides full protection functions,such asovercurrent,overheat,and braking unit open-circuit and short-circuit protection.Itsupports the setting of parameters including braking start/stop voltage,and braking rate.Multiple braking units can be deployed in master/slave mode to meet the brakingrequirements of high power drive.Inovance MDBUN braking unit also applies to large-inertia applications that requiresudden stop,for example,such as elevators,textile machines,paper making machines,centrifuges,wire drawing machines,winding machines,proportional linkage systems,andcrown blocks.Before performing installation,wiring,operation,maintenance,and inspection,read andunderstand this manual thoroughly and follow the instructions.Failure to observe theinstructions may result in personal injury or even death.Note●The drawings in this manual are sometimes shown without cover or protective guard.Remember to install the cover or protective guard as specified first,and then performoperations in accordance with the instructions.●The drawings in this manual are shown for description only and may not match theproduct that you have purchased.The instructions are subject to change due to product upgrade,specificationmodification,as well as the efforts to increase the accuracy and convenience of themanualContact the regional agent or customer service center of Inovance if the manualdelivered is lost or damaged.Contact the customer service center of Inovance if you have problems during the use.Page 1 of 24
