Неисправности преобразователя частоты. Распространённые поломки
Лёгкость эксплуатации и простота конструкции, позволило частотным преобразователям стать самыми распространёнными электротехническими устройствами в различных сферах жизнедеятельности человека. Однако поломки преобразователя частоты – не редкое явление. При их возникновении следует знать: в чём заключаются ошибки частотника, что к этому привело, и как эту проблему решить.
Распространённые виды неисправностей
Ввиду особенностей условий эксплуатации, выработанного ресурса и качества используемого инвертора, могут возникнуть различные неисправности.
Распознать их можно по дополнительным характеристикам подконтрольного устройства – электродвигателя. Лишь оценивая реакцию (либо её отсутствие), температуру, или параметры вращения подключённой электрической машины, можно констатировать факт неисправности частотного преобразователя.
Распространённые неполадки:
Не вращается двигатель;
Перегрев двигателя;
Вращение двигателя с неизменной скоростью;
Отсутствие восприятия частотником органов управления.
Причины поломок
Убедившись по реакции двигателя, что проблема именно в преобразователе, следующим верным шагом будет определение причин, вызвавших неполадку. Процесс диагностирования большинства неисправностей требует вскрытие защитного корпуса и частичной разборки инвертора.
Вероятные причины:
Осевшая пыль нарушает процесс охлаждения. В результате происходит перегрев и сокращение срока службы частотника. Токопроводящая пыль может вызвать пробой изоляции. Замыкание управляющей платы, способно спровоцировать ошибки частотного преобразователя.
2. Масляные загрязнения и эрозия. Машинное и трансформаторное масло способно причинить серьёзный ущерб преобразователю. Попавшее на электронные детали и управляющие платы инвертора масло, со временем разрушает отдельные элементы, что может привести к возгоранию и взрыву агрегата.
Самый верный способ продлить эксплуатационный ресурс устройства, это установка специального защитного корпуса. Он предотвратит попадание горюче-смазочных материалов внутрь конструкции.
3. Нарушение правил монтажа. В процессе установки и подключения преобразователя, часто встречаются следующие упущения:
— толщина сечения монтажного провода или жил кабеля менее допустимых значений;
— неправильное подключение электропроводки;
— наличие плохого электрического контакта в месте подсоединения клемм и проводов;
— нарушение изоляции жил кабеля или монтажных проводов (появляется возможность касания оголённых проводов о корпус устройства).
4. Неисправности многофункциональных клемм входа/выхода. Этот вид неполадок вызван чрезмерным износом разъёмов и клемм агрегата. Несоответствие технических условий эксплуатации также может вызвать эту проблему. При значительном превышении рабочего ресурса разъёмов, рабочие цепи входа/выхода на питающей плате могут попросту выгореть.
Типовые коды ошибок
Современные преобразователи частоты имеют собственную внутреннюю память. Она предназначена для записи всех контролируемых параметров в процессе функционирования инвертора. Имея достаточное количество данных, управляющая система способна сравнивать и анализировать собственные рабочие показатели.
На основе собранных данных, эта функция позволяет сформировать определённый код неисправности и записать его в журнал ошибок внутренней памяти. Для удобства мониторинга и диагностики неполадок, ошибки частотника выводятся на дисплей устройства. По значению кода определяют вид неисправности и пути её ликвидации.
Закодированные ошибки частотного преобразователя :
Способ устранения: настройка тепловой зашиты инвертора, методом понижения значения тока в цепи и регулировки времени срабатывания;
Способ устранения: принятие мер по поиску места обрыва недостающих фаз(ы). Для установок, где остановка двигателя недопустима, следует незамедлительно перенастроить режим работы частотника в однофазный режим;
Способ устранения: настройка и перепрограммирование номинальных токов электродвигателя и регулятора;
Способ устранения: следует добавить в цепь «тормозной» резистор, перевести работу преобразовательного устройства в режим генератора, либо перенастроить функцию защиты от перенапряжения;
Способ устранения: очистка лопастей охлаждающего вентилятора, установка дополнительного вентилятора, либо замена существующего на более мощный. Решить проблему может и установка преобразователя в более подходящее место для эффективного отвода тепла от агрегата.
Большинство программируемых инверторов при возникновении неполадок отключают управляемый электродвигатель. Однако электрические машины аварийных систем питания, преднамеренно программируют на непрерывную работу в случае любой поломки преобразователя частоты.

В процессе эксплуатации преобразователя частоты (ПЧ) рано или поздно возникают проблемы, связанные с его корректной работой. Ошибки и сбои могут происходить как при включении (настройке) частотника, так и при его эксплуатации.
При возникновении большинства ошибок преобразователь прекращает работу. Реакцию на некоторые ошибки можно программировать. Например, при возникновении сбоя ПЧ может останавливаться либо продолжать работать, выдав сообщение о неисправности. В некоторых частотных преобразователях существует так называемый «пожарный режим», когда ПЧ работает, несмотря на проблемы, вплоть до поломки и возгорания.
Для начала рассмотрим типичные сообщения об авариях и ошибках ПЧ, которые отображаются на экране пользователя. Отметим, что большинство этих сообщений передаются по каналу связи (если он присутствует) в контроллер и соответствующим образом обрабатываются.
1. Перегрузка по току
Код на дисплее: OC (Over Current). Это сообщение говорит о том, что выходной ток преобразователя частоты превысил допустимое значение. Если данная ошибка появилась при первом пуске ПЧ, необходимо проверить соответствие номинального тока частотника номинальному и реальному току двигателя – возможно, произошло замыкание внутри двигателя. В некоторых типах ПЧ перегрузка OC может разделяться на 3 разных ошибки – перегрузка по току при разгоне, при торможении, при работе на постоянной скорости.
2. Перегрузка
Код на дисплее: OL (Over Load). Данное сообщение связано с предыдущим и в некоторой степени дублирует его. Сообщение OL может высвечиваться из-за срабатывания внутренней электронной тепловой защиты двигателя, либо из-за превышения механической нагрузки на двигатель (превышения момента). Уровень перегрузки устанавливается при настройке частотного преобразователя, причем задаются как уровень тока (в амперах или процентах), так и время реакции в секундах.
3. Превышение напряжения
Код на дисплее: OV (Over Voltage). Это сообщение появляется, когда напряжение на звене постоянного тока превышает допустимый порог. В первую очередь данная ошибка возникает во время торможения, когда электродвигатель входит в режим генерации электроэнергии. Эту проблему можно решить несколькими способами – увеличить время торможения, применить тормозной резистор, отключить торможение (остановка двигателя на свободном выбеге), поднять предельный уровень ограничения перенапряжения при наличии соответствующей возможности.
4. Низкое напряжение
Код на дисплее: LV (Low Voltage). Данное сообщение может появиться, когда напряжение на звене постоянного тока падает ниже установленного порога. Возможные причины: пониженное напряжение в сети, пропадание одной из фаз. К слову, частотный преобразователь может продолжать работать без одной или даже двух фаз, если подключенный двигатель допускает работу на пониженной мощности и отключено обнаружение пропадания фазы.
5. Перегрев ПЧ
Код на дисплее: OH (Over Heat). Это сообщение говорит о том, что температура ПЧ слишком высока. В первую очередь следует проверить исправность внутренних вентиляторов преобразователя и прочистить его сжатым воздухом. Также необходимо проверить отвод тепла от ПЧ, температуру и циркуляцию воздуха внутри электрошкафа. Возможно, потребуется установить дополнительное охлаждение или уменьшить нагрузку.
Мы перечислили лишь основные сообщения о неисправностях. Их число может доходить до нескольких десятков, что позволяет точнее настраивать работу преобразователя и диагностировать неисправности. В различных моделях ПЧ эти сообщения могут индицироваться по-разному, например, в частотнике ProStar PR6000 они выглядят как Er01, Er02, и т. д., но смысл имеют аналогичный.
При ряде неисправностей преобразователей частоты сообщения на экране не выводятся. В основном, это связано с проблемами питания или с фатальными сбоями в работе ПЧ. Кроме того, если существуют проблемы с первоначальным запуском, то есть вероятность ошибки в подключении цепей управления (запуска). Рассмотрим подробнее такие неисправности.
6. Двигатель не запускается
Шаг 1. Проверяем подключение питания и электродвигателя. Шаг 2. Проверяем цепи запуска. В некоторых моделях ПЧ для запуска двигателя необходимо активировать более одного входа, например, «Пуск» и «Вперед», а также вход разрешения работы. Шаг 3. Проверяем способ задания частоты. Проще всего активировать и задать скорость вращения в панели управления, а затем, после устранения проблем, переключиться на задание скорости с внешнего источника.
7. Двигатель вращается в неправильном направлении
Чаще всего в приводах используется «правое» вращение двигателя. Изменить направление вращения можно двумя способами.
8. Двигатель не вращается с нужной скоростью
Причиной может быть неверное задание частоты, либо слишком большая нагрузка на двигатель (при неправильной уставке защиты). Также существует вероятность неверной установки значений верхней и нижней границ выходной частоты.
9. Проблемы с разгоном и торможением
Если двигатель слишком медленно разгоняется, и время разгона существенно превышает установленное, есть вероятность, что срабатывает функция токоограничения при разгоне. Если же двигатель слишком долго тормозит, то необходимо проверить в меню преобразователя настройки такого параметра, как ограничение перенапряжения, и убедиться в правильности подключения тормозного резистора.
Перегрев электродвигателя является следствием чрезмерной нагрузки на его валу. Следует принять меры по защите двигателя и частотного преобразователя путем настройки соответствующих параметров через меню.
В общем случае при возникновении неисправностей в работе преобразователя частоты следует обратить внимание на температуру двигателя и сообщения на экране, а также обратиться к руководству по эксплуатации.

Mitsubishi Diamante F27A 3.0 4WD 30R-S › Бортжурнал › Диагностика и коды неисправностей
На Mitsubishi Daimantе первого поколения как и на всех моделях Mitsubishi 1989-1994 г. Устанавливается один 12-контактный диагностический разъем, также на некоторых моделях присутствует дополнительный такой же 12-контактный разъем, но в нем задействовано только три вывода. Основной разъем белого цвета, дополнительный черного.
Основной разъем
1 — MPI
2 — EPS
3 — ECS
4 — ABS
5 — ASC
6 — ELC A/T
7 — A/С
8 — SRS
9 — ETACS
10 — DCT
11 — VSS
12 — GND «масса»
Дополнительный разъем
1 — TCL
2 — 4WS
6 — MPI (дополнительный)
Для считования кодов подключаем стрелочный вольтметр к выводу 12 (GND «масса») и выводу той системы с которой хотим считать коды, и включаем зажигание. Для двигателя 12 (GND «масса») — 1(MPI), для АКПП 12 (GND «масса») — 6(ELC A/Т), и т. д.
Код неисправности состоит из 2 цифр, первая цифра определяется по первоначальной серии колебаний стрелки вольтметра, затем после паузы 2 секунды следует вторая серия колебаний, которая соответствует второй цифре кода. Коды идут в порядки возрастания повторяясь по кругу, между кодами пауза 3 секунды. Если неисправность отсутствует, стрелка колеблется непрерывно с интервалом 0,5 секунд.
