Application Guide | VACON® NXP DCGuard™ Introduction 1.1 Purpose of this Application Guide This Application Guide provides information for configuring the system, controlling the AC drive, accessing parameters, programming, and troubleshooting of the AC drive. It is intended for use by qualified personnel. To use the drive safely and professionally, read and follow the instructions. Pay particular attention to the safety instructions and general warnings that are provided in this manual and other documentation delivered with the drive. The VACON® NXP DCGuard™ application software and this...

Application Guide | VACON® NXP DCGuard™ Introduction Illustration 1: Parameter Table Reading Guide 1.5 Application Functionality VACON® NXP DCGuard™ is a fast DC current cutter device that detects and cuts off an outgoing short-circuit current. The main function is to isolate the faulty DC grid from the healthy DC grid, before that fault affects the healthy DC grid. Two inverter units in a DCGuard peer-to-peer topology are required to be able to cut off short-circuit current both ways. VACON® NXP DCGuard™ consist of VACON® NXP inverter units and application software ADFIF102. To ensure the...

Application Guide | VACON® NXP DCGuard™ NXP3 control board VB761 revision D or newer. System software version NXP00002V193 or newer. 1.7 System Integrator Responsibilities The VACON® NXP DCGuard™ is developed to be used as a component in a common-DC system. System design and control must be done by the system integrator. The VACON® NXP DCGuard™ peer-to-peer system is made of two independent DCGuard units, although they operate as a pair. It is the responsibility of the system integrator to implement the two DCGuard units in to the system, to ensure correct functionality, and to ensure...
