Частотные преобразователи имеют отношение к сложной производственной и промышленной электроники, которая пользуется всемирно известной популярностью по всему миру. Ведь с постоянным развитием и изобретением новых технологий не существует такое промышленное предприятие, на котором бы не работал частотный преобразователь.

Однако при постоянной и непрерывной работе, даже самое надежное оборудование, может ломаться.

Часто возникающие ошибки преобразователей частоты

Преобразователи частоты созданы для управления за двигателями, моторами и полностью оснащены не слишком большими экранами, на которых появляется информация, показывающая коды ошибок. При обнаружении ошибки, пользователь может ее расшифровать и узнать истинную причину возникновения.

Некоторые ошибки преобразователей частоты устраняются автоматически, а некоторые ошибки можно устранить только при обращении в специальный сервис по обслуживанию и ремонту преобразователей.

Расшифровка ошибок

• Е01 — увеличение электрического питания при постоянной скорости вращении.
• Е02 — увеличение электрического питания в период торможения.
• Е03 — увеличение электрического напряжения во время начала работы.
• Е04 — увеличение электрического питания при работе другого режима.

Данные ошибки свидетельствует о том, что возникло замыкание частотного преобразователя, либо был заблокирован вал, либо нагрузка слишком большая. Все это привело к экстренному выключению частотного преобразователя. Причиной также может являться подключение электрических цепей с 2-мя элементами электрического питания.

• Е05 — включилась защита от перегрузки. Данная ошибка возникает при том моменте, когда электрическая функция тепловой защиты обнаружила перегрузка частотного преобразователя. В этом случае необходимо проверить возможность снижения электроэнергии пиковых токов, а также правильность параметров двигателя.
• Е06 — перегрузка тормозного резистора, в этом случае защитная функция выключает выход частотного преобразователя.
• E07 — повышенное электрическое напряжение.
• E08 — повышенная температура окружающей среды либо увеличение радиоволн.
• Е09 — пониженное напряжение приводит перегреванию частотного преобразователя.
• Е11 — сбой.
• Е14 — произошло замыкание на землю.
• Е15 — электрическое напряжение было превышено на входе. Возникает при остановке частотного преобразователя свыше полторы минуты.
• Е21 — повышенная температура теплового датчика.
• Е22 — ошибка при обмене данными между 2-мя частотными преобразователями.
• Е30 — возникает при перегрузке электрического напряжения.
• Е37 — возникает при подаче сигналов безопасного отключения и остановки.
• Е43 — ошибка программе памяти.
• Е45 — ошибка команды лига обнаружения невыполнимой команды.
• Е80 — отсоединение энкодера.
• Е81 — повышенная скорость в работе частотного преобразователя.

Список ошибок

Детализация ошибок

Список заказных кодов

Обнаружение ошибок производится с целью предотвращения повреждения преобразователя частоты. Для работы с ошибками преобразователей частоты фирмы Yaskawa в первую очередь необходимо знать назначение индикаторов модуля ЦПУ.

Для правильного определения мер по устранению проблемы необходимо четко различать ошибки (faults) и предупреждения (alarms).

Когда ПЧ обнаруживает ошибку:

• • На дисплее цифровой панели отображается соответствующий текстовый код ошибки; индикатор «ALM» не погаснет до тех пор, пока ошибка не будет сброшена.
• • С выхода ПЧ снимается напряжение, двигатель останавливается самовыбегом.
• • Для некоторых ошибок пользователь может выбрать способ остановки двигателя.
• • Клеммы выхода сигнализации ошибки MA-MC замыкаются, а клеммы MB-MC размыкаются.

Пока ошибка не устранена, работу преобразователя частоты возобновить невозможно

Когда ПЧ выдает предупреждение или обнаруживает незначительную ошибку:

• • На дисплее цифровой панели отображается соответствующий текстовый код предупреждения или незначительной ошибки; индикатор «ALM» мигает.
• • Как правило, преобразователь не прекращает вращение двигателя, хотя для некоторых предупреждений пользователь может выбрать способ остановки.
• • Если один из многофункциональных релейных выходов сконфигурирован для сигнализации незначительных ошибок (H2- †† = 10), этот выход замыкается (предупреждение к замыканию выхода не приводит).

Для сброса незначительной ошибки или предупреждения следует устранить причину возникновения

• Page 283: Handling

  Handling Observe the following precautions when wiring or performing maintenance for an Inverter. Wiring Check The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W. Check wiring for any mistakes before supplying power. Check all wiring and control sequences carefully. Magnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line.

• Page 284: Motor Application Precautions

  Installation Withstand Voltage If the input voltage is high (480 V or higher) or the wiring distance is long, the motor insulation voltage must be considered. Contact your Omron Yaskawa Motion Control representative for details. Acoustic Noise Noise varies with the carrier frequency. At high carrier frequencies, the noise is almost the same when the motor is operated with a commercial power supply.

с основным прибором. Соедините его пра-

вильно и затем произведите измерение.

• Проверьте,  не  изогнута  ли  резиновая 

трубка,  соединяющая  манжету  с  основ-

ным  прибором.  Выпрямите  ее  и  затем 

произведите измерение.

• Проверьте, плотно ли наложена манжета. 

Наложите ее правильно и затем произве-

дите измерение.

Er2

Сбой в процессе сброса давления.

• Скорость сброса давления в процессе изме-

рения слишком велика.

• Скорость сброса давления в процессе изме-

рения слишком мала.

• Процесс  измерения  не  заканчивается  за  ус-

тановленное время.

• Давление поддерживается более 5 минут.

Er3

Слишком высокое давление.

• Давление в манжете достигает значения бо-

лее 299 мм рт. ст.

• Проверьте,  не  изогнута  ли  резиновая 

трубка,  соединяющая  манжету  с  основ-

ным  прибором.  Выпрямите  ее  и  затем 

произведите измерение.

Er4

Давление нагнетания недостаточно большое.

• Артериальное давление не может быть изме-

рено вследствие недостаточного нагнетания.

• Если  измерение  производится  при  уста-

новке  переключателя  выбора  режимов 

P-SET  в  положение  AUTO,  попросите 

пациента  не  шевелить  рукой  и  сохранять 

неподвижность в процессе нагнетания.

• Если  переключатель  выбора  режимов 

установлен в положение AUTO, поверните 

переключатель  против  часовой  стрелки, 

до щелчка.

• При  помощи  переключателя  P-SET  уста-

новите давление нагнетания на 30 – 40 мм 

рт.  ст.  выше  ожидаемого  систолического 

давления  и  затем  произведите  измере-

ние.

Er5

Невозможно определить артериальное давление.

• Артериальное  давление  невозможно  изме-

рить, несмотря на то, что давление, поданное  

в манжету, достигло заданной величины.

• Проверьте, плотно ли наложена манжета. 

Наложите ее правильно и затем произве-

дите измерение.

Er6

Пульсовая волна слишком слаба.

• Проверьте, плотно ли наложена манжета. 

Наложите ее правильно и затем произве-

дите измерение.

• Не  накладывайте  манжету  на  одежду  из 

плотной  ткани  или  поверх  закатанного 

рукава пиджака или рубашки.

Er7

Ошибка измерения.

• Ненормальное  соотношение  между  систоли-

ческим и диастолическим давлением.

• Проверьте, не страдает ли пациент арит-

мией.

• Попросите пациента не шевелить рукой и 

сохранять неподвижность во время изме-

рения.

Er8

Ошибка в определении пульсовых волн.

• Частота пульса выходит за пределы диапазо-

на 30 – 199 уд/мин.

Er9

Ошибка прибора.

• Неисправность  основного  блока  измерителя 

артериального давления.

• Свяжитесь  с  Вашим  дилером  или  с  бли-

жайшим отделением фирмы OMRON.
