Description Danfoss 178B8577 - Compact General Purpose Inverter Drives Advanced and versatile, the VLT 2800 is an ideal general purpose inverter drive. 178B8577 is a Three Phase, 1.7A, 0.55 kW inverter drive with a 380...480V AC supply. These modular AC drives consist of a power module and a control module and mountable side-by-side saving you installation space and money. For the low power market, the VLT 2800 range is ideal. Smart and safe to benefit your application Product safety A number of safety features are included such as 100% earth fault protection and mains transient protection. Other safety features include galvanic isolation and both switching on input and output. Intelligent 178B8577 enjoys a number of features that make it an intelligent part of your system. Bus communication, precise stop, pump and wobble functions make it suitable for many industrial applications. Bus communications Bus communications including DeviceNet, Profibus DP, Modbus RTU and Metasys allow your 0.55 kW inverter drive to communicate with other devices in your system. Applications for your Danfoss 0.55 kW inverter drive The whole VLT 2800 series is designed for stable operation in industrial environments. You can use your 0.55 kW AC drives in many applications including: Pump Fan Conveyor Extruder Mixer Wrapper Gantry crane (small loads) Cutting Rotor spinning Winder Wobble Dedication to your application The VLT 2800 family has a selection of additional features that are designed to optimise operation and protection of system components for typical applications. Built-in wobble function On a textile winder the wobble function is used for the traverse function. {part num} operates a motor, which turns a grooved drum. During winding, the grooved drum places the thread in a diamond pattern in the correct position on the bobbin. When the traverse drum operates at a constant speed, the thread crosses at the same position for each pass, which results in loose and less compact winding on the bobbin. Precise stop On a conventional inverter drive, digital inputs are scanned periodically - this initiates the Stop command. With a periodical scan, uneven delays can be caused as the drive scans all other parts of the program. VLT 2800 solves this problem as the Stop command is an interrupt rather than part of the scan, typically reducing deviation from ±10 mm to ±1 mm Counter precise stop After the start signal is received the VLT 2800 operates until the number of of pulses is seen at terminal 33. A Stop signal is generated and the normal stop ramp is used. The counter stop signal is then re-armed and ready again for a new start command. The pulse input is designed to handle 24 V push-pull pulses from an encoder with up to 1024 ppr. The maximum pulse rate is 67,600 Hz.
