Добрый день подскажите как настроить привод sgdh-01ae-oy, чтобы он работал от сигнала разрешения на пуск и от импульсов внеред-назад?

Павел Русин 06.10.2016

Добрый вечер!
Это ошибка означает «потеря связи с энкодером». Необходимо проверить подключение кабеля датчика обратной связи, либо у Вас повреждён энкодер.

Добрый вечер при запуске серво привода высвечивается ошибка АС9 подскажите что это такое и как с этим боротся

А.И 20.09.2016

Здравствуйте, Виктор! -OY это стандартная версия, -Y12 какая-то специализированная версия, возможно изготовлена под конкретного OEMа.

Александр, Драйвика 07.09.2016

Здравствуйте,

Скажите пожалуйста в чем различие моделей SGDH-15DE-OY и SGDH-15DE-Y12.

Васильчук Виктор 07.09.2016

Добрый день!
Данная ошибка означает, что мотор отключен от преобразователя, либо момент на валу двигателя менее 10% от заданного.

Андреев Юрий, support@driveka.ru 14.10.2015

Здравствуйте, мониторе sgdm-15 не документированная ошибка AF5. Подскажите порядок действий на сообщение.

Как правило,это происходит из-за ошибок энкодера,или проблем с кабелем Начать нужно с проверки кабеля,при этом ,обрати особое внимание на экран!Если кабель лежит рядом с высоковольтными цепями,неизбежны наводки на провода и тут качество экрана и его привязка к корпусу машины очень важна!
Есть еще одна тонкость:-правильная регулировка энкодера на движке!Если обмотки движка жужжат в положении «СТОП»,-это говорит о неправильной регулировке энкодера!Особенно это типично для энкодеров тип «ERN-1381″и всей этой серии Регулировка делается очень просто:-ослабляются крепления корпуса(НЕ ПЫТАЙТЕСЬ ЕГО СНЯТЬ ВНАХАЛКУ,ОТКРУТИВ ЦЕНТРАЛЬНЫЙ БОЛТ!!!ЛОПНЕТ ДИСК! Снять его полностью можно только съемником!)и энкодер потихоньку проворачивают по часовой стрелке,до исчезновения жужжания :-рисуешь на этом месте метку и плавно,без рывков поворачиваешь обратно,до возникновения жужжания и ставишь вторую метку,-расстояние между метками -рабочая зона!Лучше фиксировать болты посредине рабочей зоны!
Вот тут можно кое-что почитать!

Доброе утро страна. На какой скорости вращения проявляется этот дефект? Если брать за ось самого двигателя при самой маленькой скорости вращения биения всегда проявляются.

  • 25 Сен 2014

Это происходит при 0 скорости. И если дать вращение он крутится с сильгной вибрацией.

  • 25 Сен 2014

Доброе утро страна. Сервоблок разбирал? Поменяй кондеры на плате, лучше промой спиртом плату возле кондеров. Ошибка на дисплее сервопака появляется?

Добавлено 25-09-2014 11:44

Плата на сервопаке у тебя SGDH-CB10? Если эта плата проверь резисторы R78, R79. Они выгорают иногда, правда они влияют только на работу вентилятора. Замени кондер С26 на 100 х 25. Стоит 33 планарный.

  • 25 Сен 2014

Сервоблок пока не разбирал.Уменьшил параметр Pn100 с 40 до 30( усиление ОС по скорости)Все заработало. Через неделю снова повторилось. Еще уменьшил с 30 до 20. Пока работает.

Да и когда крутишь движок с кнопок сервопривода-ничего не вибрирует. А вибрирует только когда задание идет с контроллера.

Доброго времени суток!Попался на ремонт станок с сервоприводом OMRON sgdh-15DE-OY c дополнительным блоком MCW151.Станок бездействовал два года!При запуске обнаружилось,что при старте набирает максимальную скорость и не останавливается пока не нажмеш аварийный стоп.Управляется с релейного блока,все реле отрабатывают как надо!Когда работал нормально,при нажатии кнопки пуск прокручивался на определённый градус,притормаживал и останавливался не зависимо от того в каком состоянии кнопка пуск.При повторном нажатии кнопки всё повторяется. Могут ли настройки сервопривода сброситься за 2 года и если да то где взять инструкцию по настройке?Датчика на стоп движения не предусмотрено ,мотор должен плавно стартовать и прокрутится определённое количество шагов плавно остановится.Описание по ссылке выше скачал но мне нужна пошаговая инструкция по настройке .
Пожалуйста помогите если не трудно!

  • 9 Май 2016

Батарейки есть в приводах?(только не вытаскивай на выключенном если есть).

Добавлено 09-05-2016 17:44

С релейного блока точным положением вала сложновато управлять, обычно импульсами с высокоскоростных выходов контроллера или (может быть) с mcw151. А ещё по цифровому интерфейсу.

  • 5 Апр 2017

Встречали и такое ,промучились с ним долго и швп и чпу.В итоге в стойке обнаружили кучу разъемов ,а в них оторванные экраны.Запаяли на место и рысканье прекратилось.

Добрый день!
Возникла проблема с похожим устройством, нужны коды ошибок.
Частотник SGDH -05DE-OY выдает ошибку А.41 (или R.41) с чем это может быть связано?

Сервопривод Sigma II (Omnuc W — старое название серии) компании OMRON предназначен для оптимального управления скоростью и положением подвижных деталей механизмов. Реализованные на базе 32-разрядного RISC-процессора, сервосистемы обеспечивают оптимальное регулирование по току и по скорости и снабжены функцией оперативной автоматической подстройки. Эта функция в процессе работы непрерывно адаптирует параметры управления к изменяющимся условиям нагрузки и обеспечивает превосходные динамические характеристики. Благодаря этой функции сервосистемы OMRON соответствуют самым строгим требованиям современных высокоточных промышленных систем, включая системы упаковки, станки подготовки высокоточного инструмента, манипуляторы поточных линий полупроводниковых схем, а также сверлильные станки для печатных плат и фасонно-фрезерные станки.

OMRON Sigma II — это полный модельный ряд сервоприводов — от одно- и трехфазных сервоприводов с напряжением питания 230 В до трехфазных сервоприводов с напряжением питания 400 В, со скоростью вращения от 1000 до 6000 оборотов в минуту и мощностью от 30 Вт до 15 кВт. Кроме того, для оптимизации работы заказчика, компания OMRON предлагает широкий выбор кабелей питания, приводов и фильтров.

Исследования показали, что продукция OMRON является одной из самых надежных на рынке, и семейство W не является исключением. Разработанные с учетом многолетнего опыта серводвигателей, приводов и сопутствующих устройств, сервосистемы семейства W компании OMRON созданы с расчетом на круглосуточную, надежную и высококачественную работу.

Вдвое уменьшив время вычислений, затрачиваемое ЦПУ устройств семейства W, и оптимизировав алгоритмы вычислений, компания OMRON сократила период отсчета положения на 1/3 по сравнению с предыдущими системами, что является очень весомым достижением в машиностроении.

Сервосистемы семейства Sigma II (Omnuc W) компании OMRON поддерживают технологию Plug & Play. Достаточно подсоединить сервосистему к механизму, перевести ведущий сервопривод в режим оперативной автоподстройки — и он автоматически точно настрои параметры в соответствии с работой механизма. Сервопривод позволяет даже распознать мощность серводвигателя и разрядность датчика положения, а затем подстроить свои параметры. .

График оперативной автоподстройки сервопривода Omron

Двигатели этой серии надежны, динамичны, обеспечивают высокую точность и высокую производительность. Выпускаются двигатели со скоростью вращения до 6000 оборотов в минуту и с диапазоном управления скоростью 1:5000, точностью задания вращающего момента 2% и кратковременной допустимой нагрузкой 312%.

Пространство для размещения двигателя и привода значительно сокращено. Такая компактность достигается за счет технологии поверхностного монтажа и минимального использования внутренней проводки. Характеристики семейства Sigma II (Omnuc W) превосходят промышленные стандарты на габариты и удельную мощность для устройств своего класса типоразмеров, обеспечивая максимальную производительность станков и линий заказчика при сверхкомплектности и минимальных затратах.

Разработав передовую последовательную связь между приводом и датчиком положения, компания OMRON сократила число проводов между сервоприводом и датчиком положения серводвигателя. Число проводов сократилось для импульсного датчика положения серводвигателя с 9 всего до 5 проводов, а для абсолютного датчика положения — с 15 до 7 проводов.

Все сервоприводы семейства Sigma II (Omnuc W) имеют резонансную схему фильтрации, которая нейтрализует высокочастотный механический шум. Предусмотрена эталонная схема фильтрация вращающего момента, которая автоматически подавляет резонанс оси. Все сервоприводы компании OMRON обеспечивают мгновенную компенсацию выявленных вибраций. Эти функции гарантируют плавную и бесшумную работу всех сервосистем компании OMRON.

Компания OMRON предоставляет на выбор ряд двигателей и кабельных разъемов, которые изолированы в соответствии со стандартом на класс защиты IP 67.

Программный пакет компании OMRON для определения типоразмера (программа выбора двигателя) вычисляет параметры идеального серводвигателя для конкретной системы, поэтому заказчик точно знает, какую модель заказать для получения оптимальных результатов. С помощью этой программы заказчик сможет спроектировать механическую систему, а программа подберет требуемый серводвигатель Sigma II (Omnuc W).
