Omron varispeed v7 ошибка ol2

6 минут назад, Ruslan68 сказал:

Кто нибудь знает что еще настроить?

Пользую такой же частотник 18квт. Брал б/у. Не с того ни с сего стала выскакивать ошибка КЗ на землю. Все перепробовал, и настройки, и провода менял, и мотор мегометром смотрели.

Потом вскрыл частотник, крепеж весь был расслаблен, откинул верхнюю плату, чтоб подобраться к остальным болтам. Один из болтов прикручивающий провод какого то датчика почти открутился, видимо от вибрации пропадал контакт. Ошибка возникала раз-два в сутки, хаотично.

Протянув весь крепеж, проблема ушла. И уже пол-года не проявляет себя. Может и у вас проблема где то в незатянутом крепеже.

Стандартные ошибки и проблемы

  1. Параметр не может быть изменён.

Возможные причины:

  • Параметр заблокирован. Это означает, что в настройках ПЧ была активирована защита от изменения параметров. Для деактивации этой защиты необходимо присвоить параметру Pb18 (у устройств Innovert ISD mini и mini PLUS этот параметр отвечает за блокировку доступа к параметрам). значение «0». В случае, если при работе с mini PLUS невозможно присвоить параметру Pb01, который отвечает за способ установки заданной частоты, определенное значение (канал Х), то это означает, что такое значение уже выставлено по другому каналу и необходимо проверить его настройку, просмотрев значение параметра Pb20 (канал Y).
  • Неправильная передача данных. Для решения этой проблемы необходимо перепроверить соединительные провода и подключить их заново к клеммам, отключив предварительно питание.
  • Двигатель работает. У ПЧ существует защита от изменения значений параметров при работе двигателя, поэтому для изменения параметров необходимо предварительно остановить двигатель.
  1. Перегрев двигателя.

Возможные причины:

  • Температура окружающей среды превышает допустимую. Решение: принятие мер для её понижения
  • Нагрузка на двигатель превышает номинальный вращающий момент. Решение: уменьшить нагрузку, поставить редуктора или заменить двигатель на более мощный.
  • Повреждение изоляции двигателя. Решение: замена двигателя.
  • Большое расстояние между двигателем и ПЧ. Решение: уменьшение расстояния между ПЧ и двигателем, а также установка дросселя переменного тока.
  • «Жёсткий режим» запуска двигателя. При включении двигателя по его обмоткам протекает большой ток. Решение: уменьшение величины максимального кратковременного тока, замена двигателя на более подходящий.
  • Двигатель работает на низкой скорости. Решение: установка понижающего редуктора, чтобы обеспечить работу двигателя на более высокой скорости.
  1. Двигатель не запускается при нажатии кнопки «ПУСК» на внешнем пульте управления.

Возможные причины:

  • Установлен неправильный режим работы. Решение: проверить параметр Pb02, ему должна быть присвоена «1».
  • Нет задания частоты или заданная частота меньше, чем пусковая. Решение: повышение частоты.
  • Двигатель не подключен. Решение: проверка подключения двигателя.
  • Неправильно запрограммирована функция входной клеммы, внешний соединительный провод подключен к другой клемме. Решение: необходимо проверить параметры Pd15 – Pd22 (у ISD mini) или параметры Pd15-Pd18 (у ISD mini PLUS).
  • ПЧ находится под действием защиты. Решение: отключить ПЧ, устранить причину, которая вызвала срабатывание защиты и только после её устранения запустить ПЧ.
  • Двигатель неисправен. Решение: проверка двигателя.
  • ПЧ неисправен: Решение: проверка работы ПЧ на заведомо исправном двигателе, контролируя его фазный ток.
  1. Двигатель вибрирует или шумит.

Возможные причины:

  • Заклинивание ротора двигателя или отсутствие смазки. Решение: проверка нагрузки двигателя, проверка смазки.
  • Резонансная вибрация двигателя. Решение: изменение частоты ШИМ, изменение времени ускорения/торможения, установка антивибрационных прокладок, установка зоны пропуска частоты, совпадающей с резонансной.
  1. Двигатель не работает в режиме реверса.

Возможные причины:

  • Возможность вращения назад у двигателя – заблокирована.

Решение:

  • Параметру Pb04 присвоить значение «1», предварительно уточнив безопасность реверсивного пуска.
  1. Двигатель работает в режиме реверса.

Возможные причины:

  • Перепутан порядок подключения выходных клемм двигателя.
  • Задан соответствующий управляющий сигнал.

Решение:

  • изменение управляющего сигнала.
  • изменение порядка подключения выходных клемм двигателя
  1. Запуск ПЧ нарушает работу других устройств.

Возможные причины:

  • ПЧ выступает в качестве источника электромагнитных помех.

Решения:

  • Уменьшение частоты ШИМ.
  • Правильное заземление ПЧ и двигателя отдельными толстыми медными проводами.
  • Соединение ПЧ и двигателя экранированным кабелем, экран которого должен надёжно соединяться с корпусом двигателя, а с другой стороны кабеля – с монтажной металлической панелью, на которой установлен ПЧ. Панель должна быть надежно заземлена.
  • Установка выходного дросселя переменного тока на силовом выходе ПЧ.
  • Установка специального высокочастотного фильтра на силовом входе ПЧ.
  • Проложить проводку силового кабеля не ближе 10 см от проводки управляющего контура.

Коды ошибок частотного преобразователя INVTЧастотные преобразователи относятся к сложной промышленной электронике достаточно дорогой и в тоже время широко распространенной по всему миру. На сегодняшний день трудно себе даже представить какое-либо производство, на котором бы не работало данное промышленное оборудование.

К сожалению, в процессе эксплуатации выходит из строя даже самое надежное промышленное оборудование. В данной статье мы разберем частотный преобразователь INVT, точнее ошибки частотного преобразователя INVT серии GDXXX, коды ошибок и их расшифровка. Частотники в наше время нашли широкое применения в абсолютно всех сферах промышленности управляя как мини моторами в оргтехнике, так и гигантскими двигателями в горнодобывающей промышленности.

Предупреждение (несущественная неисправность) выводится при возникновении ненормальных условий работы, вследствие чего преобразователь частоты может выдать сигнал предупреждения. Предупреждение не влияет на работоспособность преобразователя частоты: двигатель продолжает работу, если запущен или его можно запустить, если он остановлен. Предупреждение сбрасывается автоматически при устранении причины.

Преобразователь частоты может иметь следующие неисправности в процессе использования, поэтому, пожалуйста, обратитесь к следующим методам для простого анализа неисправностей: Нет индикации для включения: Проверка, соответствует ли входная мощность номинальному напряжению данного устройства с помощью мультиметра. Пожалуйста, проверьте и устраните проблемы с питанием, если таковые имеются. Проверка, не поврежден ли трехфазный выпрямительный мост. Если выпрямительный мост был взорван, обратитесь за помощью. Воздушный выключатель отключается при включении питания: проверяется, есть ли заземление или короткое замыкание между входным источником питания, и устраняет проблему. Проверьте, не поврежден ли выпрямительный мост, и, если так, обратитесь в сервисную службу. электродвигатель не вращается после работы преобразователя частоты: Проверьте, есть ли сбалансированное трехфазное выходное напряжение между U, V и W. Если это так, линия электродвигателя или она повреждена, или ротор электродвигателя заблокирован по механическим причинам. Пожалуйста, исключите их. Выходное напряжение U, V и W, но трехфазное несбалансированное, это должно быть из-за повреждения платы привода ПЧ или модуля вывода, поэтому обратитесь за помощью. Если выходное напряжение отсутствует, плата водителя или выходной модуль могут быть повреждены, обратитесь за помощью. Преобразователь частоты с включенным питанием отображается нормально, а воздушный выключатель сработал после срабатывания: Проверьте, нет ли короткого замыкания между выходным модулем. Если это так, пожалуйста, обратитесь в службу поддержки. Проверьте, нет ли короткого замыкания или заземления между выводами электродвигателя. Если так, пожалуйста, исключите это. Если операция отключения происходит время от времени и расстояние между электродвигателем и инвертором относительно велико, рассмотрите возможность добавления реактора переменного тока.

Ошибки частотных преобразователей: примеры и коды ошибок

Частотные преобразователи — это электронные или электротехнические устройства, предназначенные для изменения и регулировки частоты электрического напряжения. Сфера их использования очень широка: насосные станции, системы тепло- и водоснабжения, линии производства, конвейеры, лифты, центрифуги, мельницы, металлургические агрегаты, буровое оборудование и т. д.

Использование частотных преобразователей на промышленных объектах дает следующие преимущества:

  • Возможность отказаться от регулирующего оборудования: дросселей, вариаторов, редукторов и др. Это существенно упрощает работу механической системы, снижает расходы на эксплуатацию и повышает ее надежность.
  • Плавный разгон управляемого двигателя, защищающий его от механических ударов и пусковых токов, что продлевает срок его службы.
  • Частотные преобразователи в паре с асинхронными двигателями можно использовать в качестве альтернативы для приводов постоянного тока.
  • Максимально рациональное регулирование скорости контролируемых двигателей и связанных с этим технологических процедур.
  • Экономия электроэнергии, благодаря устранению ее неоправданных трат.

Но, несмотря на свою надежность и эффективность, частотные преобразователи, как и любые электронные приборы, подвержены износу. Инженерная компания 555 специализируется на ремонте промышленной электроники, и в частности — на устранении ошибок частотных преобразователей. Наши специалисты готовы отремонтировать вышедшее из строя оборудование в кратчайшие сроки.

Основные виды и причины неисправностей

Опознать неисправности частотников позволяют коды ошибок, высвечивающиеся на мониторе устройства. Каждая такая комбинация символов указывает на совершенно конкретную проблему, и это помогает специалистам выработать правильную стратегию ремонта. Для начала рассмотрим типовые виды ошибок частотных преобразователей:

  1. Over Current или OC. Данный сигнал на мониторе устройства свидетельствует о его перегрузке. Если подобная проблема возникла при тестовом запуске, необходимо проверить соответствие токов регулятора и электрической машины, а также исправность электроцепей управляемого двигателя. Следует учесть, что некоторые модели частотников высвечивают ошибку Over Current при торможении, работе и запуске электродвигателя.
  2. Over Heat или ОН. Это сообщение указывает на превышение номинально допустимой температуры частотного преобразователя. Проще говоря — на его перегрев. Устранить проблему можно посредством чистки внутреннего вентилятора или установки дополнительной вентиляционной системы в бокс, где располагается преобразователь. В качестве профилактики следует размещать частотник в месте, гарантирующем эффективный отвод тепла.
  3. Over Load или OL. Такая ошибка преобразователя может быть вызвана двумя обстоятельствами: превышением на валу момента силы или перегревом управляемого двигателя. Чтобы устранить проблему, необходимо выполнить корректную настройку тепловой защиты. Для этого во время программирования устройства нужно задать требуемую величину тока и время срабатывания защитной функции.
  4. Low Voltage или LV. Ошибка высвечивается при снижении напряжения питания или обрыве фаз (одной или двух). Существует два варианта решения этой проблемы: «насильственная» остановка двигателя или настройка его работы в однофазном режиме.
  5. Over Voltage или OV. Такую надпись можно увидеть на мониторе при замедлении вращения двигателя. Для устранения неисправности необходимо воспользоваться одним из трех способов: переводом устройства в режим генератора, активацией тормозного резистора или перенастройкой системы защиты от повышенного напряжения.

Среди других типовых неисправностей преобразователя следует выделить вращение двигателя в неправильном направлении, невозможность его запуска, проблемы с торможением и разгоном и т. д. Каждое повреждение имеет под собой конкретные причины. Например, если двигатель разгоняется очень медленно, скорее всего, дело в срабатывании функции токоограничения в момент разгона.

В число наиболее распространенных причин неисправностей входят:

  1. Заводской брак. Как правило, фабричные дефекты дают о себе знать в течение гарантийного срока. Поэтому для их устранения следует обращаться к поставщику или в брендовый сервисный центр.
  2. Ошибки при монтаже. Чаще всего причиной неисправностей становится некорректная сборка схемы привода или установка частотника в неподходящем месте.
  3. Нарушение норм эксплуатации. Регламент технического обслуживания изложен в инструкции, прилагаемой к устройству. Игнорирование регламента может привести к выходу из строя полупроводниковых элементов, перегреванию частотного регулятора и другим неисправностям.
  4. Несоответствие частотного преобразователя условиям его эксплуатации. Основные критерии выбора частотника — электрические характеристики двигателя, исполнение, набор функций и т. д. Несоответствие параметров условиям его эксплуатации приводит к некорректной работе устройства, выходу из строя и многочисленным поломкам.

Теперь поговорим об ошибках преобразователя частоты более подробно и предметно. В качестве примера рассмотрим привод известного китайского бренда INVT ELECTRIC CO, серии GDXXX. Предлагаем вашему вниманию таблицу, в которой представлены коды ошибок устройства, их расшифровка, вероятные причины неисправностей, а также способы их устранения.

Код ошибки Расшифровка Вероятные причины Способы устранения
OUt1, 2, 3 Ошибка фазы. Отсутствие заземления или контакта при подсоединении кабеля; слишком маленькое время разгона. Увеличение времени разгона;
замена модуля IGBT; устранение неисправностей внешнего оборудования; переподключение кабеля.
OC1, 2, 3 Токовая перегрузка при разгоне, торможении или постоянной скорости. Чрезмерное время торможения или разгона; слишком высокое напряжение в сети; недостаточная мощность привода;
потеря фазы или короткое замыкание «на землю»; воздействие внешнего фактора.		 Сокращение времени разгона;
оптимизация питающего напряжения;
приобретение привода с более высокой мощностью; проверка конфигурации выхода;
устранение внешних помех.
OV1, 2, 3 Сверхнапряжение при разгоне, торможении или постоянной скорости. Напряжение на входе не соответствует параметрам привода;

  • Page 150
    Deceleration to Stop If the stop command is input (the run command is turned OFF) when b1-03 is set to 0, the motor decelerates to stop according to the deceleration time that has been set. (Factory setting: C1-02 (Deceleration Time 1)). If the output frequency when decelerating to stop falls below b2-01, the DC injection brake will be applied using the DC current set in b2-02 for the time set in b2-04.

    Error Check Errors during communications are detected using CRC-16 (cyclic redundancy check, checksum method). The result of the checksum calculation is stored in a data-word (16 bit), which starting value is FFFH. The value of this word is manipulated using Exclusive OR- and SHIFT operations together with the data package that should be sent (slave address, function code, data) and the fixed value A001H.
  • Page 210
    The following example clarifies the calculation method. It shows the calculation of a CRC-16 code with the slave address 02H (0000 0010) and the function code 03H (0000 0011). The resulting CRC-16 code is D1H for the lower and 40H for the higher byte. The example calculation in this example is not done completely (normally data would follow the function code).
