VLT 2800 Quick Guide 1 Quick Guide Connect all earthing systems to ensure the lowest possible conductor impedance. The lowest possible conductor impedance is achieved by keeping the conductor as short as possible and by grounding with the greatest possible surface area. If multiple drives are installed in a cabinet, the cabinet backplate, which must be made of metal, should be used as a joint earth reference plate. -

Three phase VLT frequency converters require an RCD type B. If an RFI filter is mounted in the drive and either the switch of the RCD or a manually operated switch is used to connect the drive to the mains voltage, a time delay of minimum 40 ms is required (RCD type B). -

Настройку параметров
преобразователя частоты VLT2800
производят, используяпанель местного
управления.Панель местного управлениярасположена непосредственно на передней
крышке преобразователя частотыVLT2800.
Внешний видпанели местного управленияприведен на рис. 2.1.
Рис.
2.1. Панель местного управления
Панель управления
разделена на четыре функциональные
части:
-
Шестиразрядный
светодиодный дисплей. -
Кнопки для изменения
параметров и выбора функции отображения. -
Светодиодные
индикаторы. -
Кнопки для местного
управления.
Все данные
отображаются на шестиразрядном
светодиодном дисплее, позволяющем
непрерывно отображать один из рабочих
параметров во время нормальной работы
преобразователя частоты. Кроме дисплея
на панели местного управления установлены
три светодиодных индикатора, указывающие
включение питания (ON),
наличие предупреждения (WARNING)
и аварийного сигнала (ALARM).
Большинство параметров преобразователя
частоты можно изменить с панели
управления, если только для параметра
018Блокировка изменения параметровне было задано значение 1 –Заблокировано.
Кнопка «QUICKMENU» обеспечивает доступ
к параметрам, используемым в быстром
меню.
Кнопка «CHANGEDATE» используется как для
изменения значения параметра, так и для
подтверждения изменения значения
параметра.
Кнопки «+» и «–»
используются для выбора параметров и
для изменения значения параметров. Эти
кнопки используются также в режиме
отображения для выбора рабочих параметров.
Для получения
доступа ко всем параметрам кнопки «QUICKMENUи +» следует нажать
одновременно.
Кнопка «STOPRESET» используется для
останова подключенного двигателя или
для сброса преобразователя частоты
после отключения. Кнопка может быть
выбрана какАктивная«1», так иНеактивная«0» в параметре 014Местный
останов/сброс. В режиме отображения
при включении функции останова изображение
на дисплее будет мигать. Если в параметре
014Местный останов/сброскнопка
«STOPRESET»
выбрана какНеактивная«0» и команда
останова не поступает на дискретные
входы или по последовательному каналу
связи, то двигатель может быть остановлен
только путем отключения преобразователя
частоты от сети электропитания.
Кнопка «START»
используется для запуска преобразователя
частоты. Эта кнопка всегда активна.
После
перепрограммирования преобразователь
частоты можно возвратить в исходное
состояние. Для этого необходимо отключить
сетевое напряжение. Удерживая три кнопки
«QUICKMENU», +
и «CHANGEDATE»
нажатыми, включите напряжение сети.
Отпустите кнопки. Теперь преобразователь
частоты снова запрограммирован на
заводские установки.
Программировать
преобразователь частоты VLT2800
можно также, используя выноснуюместную
панель управленияпреобразователя
частотыDanfossFC– 302. Для этого случая последовательность
действий описана в лабораторной работе
№2.
2.1. Режим вывода данных на светодиодный дисплей
При нормальной
работе по выбору оператора на дисплее
может непрерывно отображаться один из
рабочих параметров. С помощью кнопок
«+» и «–» в режиме отображения могут
выводиться следующие физические
величины:
-
Выходная частота
преобразователя, Гц; -
Выходной ток, А;
-
Выходное напряжение,
В; -
Напряжение
промежуточного звена постоянного тока,
В; -
Выходная мощность,
кВт; -
Масштабированная
выходная частота, о.е.
Например, при
выборе физической величины «Выходная
частота преобразователя» на экране
дисплея появится сообщение:
