Преобразователь частоты (ПЧ) – сложное устройства управления электрическим двигателем. В случае нештатных и аварийных ситуаций ПЧ выдает сообщения об аварии или предупреждении на панель частотника или по линии связи в контроллер, так же может остановить двигатель во избежание поломок оборудования. На панели частотника выдается код ошибки. В данной статье приведены коды ошибок, их детальное описание и возможные причины появления.

Типы сообщений

Существует несколько типов сообщений:

• A – предупреждение, выводится в случае появления неаварийных ситуаций, на которые необходимо обратить внимание. Сброс при исчезновении причины предупреждения
• F – ошибка, выводится в случае появления аварийных ситуаций. Сброс при исчезновении причины отказа и подтверждения данного отказа.
• N – сообщение отсутствует или «внутреннее сообщение».
• C – сообщение безопасности.

Предупреждение. Код сопровождается буквой A. Выводятся в случае появления неаварийных ситуаций, на которые стоит обратить внимание. Сбрасываются при исчезновении причины предупреждения.

Отказ. Код сопровождается буквой F. Выводятся в случае появления аварийных ситуаций. Сбрасываются при исчезновении причины отказа и подтверждения данного отказа.

Индикация

На частотнике присутствует индикатор с обозначением RDY с помощью которого можно определить наличие отказов.

Мигающий красный индикатор один раз в пол секунды – обозначает отказ.

Коды отказов частотника:

Возможные причины:

• Эффективная граница тока установлена слишком низкой;
• Регулятор тока настроен неправильно;
• Режим U/f: время разгона установлено слишком маленьким или слишком высокая нагрузка;
• Режим U/f: короткое замыкание в кабеле двигателя или замыкание на землю;

Указание: Перепутывание кабелей питания и двигателя также определяется как короткое замыкание со стороны двигателя. Проверка на предмет замыкания на землю функционирует только в состоянии покоя двигателя. Включение на не размагниченный или только частично размагниченный двигатель может определяться как замыкание на землю.

Возможные решения:

F07900 (N, A) — Привод: двигатель заблокирован

Возможные причины:

• Двигатель работает дольше, чем время в p2177, на границе момента вращения и ниже установленного порога числа оборотов в p2175. Это сообщение может появиться, если число оборотов колеблется, и выход регулятора числа оборотов постоянно кратковременно доходит до ограничения. Возможно и то, что тепловой контроль силовой части уменьшает границу тока (см. p0290) и из-за этого происходит торможение двигателя.

Возможные решения:

• Проверить двигатель на предмет свободного движения.
• Проверить эффективную границу момента вращения.
• Проверить и при необходимости исправить параметры сообщения «Двигатель заблокирован».
• Проверить разрешения направления вращения при рестарте двигателя на лету.
• Для управления U/f: проверить границы тока и время разгона.

F07902 (N, A) — Привод: двигатель опрокинут

Возможные причины:

• Было обнаружено, что двигатель опрокинут дольше, чем установлено в p2178.

Возможные решения:

• Следует убедиться, что как идентификация параметров двигателя, так и измерение при вращении, были выполнены.
• Проверить, не опрокидывается ли привод в управляемом режиме или когда заданное значение скорости еще ноль, только нагрузкой. Если да, то увеличить заданное значение тока через p1610.
• Если время возбуждения двигателя (p0346) было сильно уменьшено и привод опрокидывается при включении и немедленном начале движения, то снова увеличить p0346.
• Проверить, не имеет ли место выпадение фазы сети у силовых частей PM230, PM250, PM260.
• Проверить, не отсоединена ли электропроводка к двигателю (см. A07929).
• Если ошибки отсутствуют, то можно увеличить отказоустойчивость (p1745) или время задержки (p2178).
• Проверить предельный ток. При слишком низких предельных токах намагничивание привода невозможно.
• Если возникает ошибка со значением 2 при очень быстром разгоне двигателя в области ослабления поля, то путем уменьшения p1596 или p1553 можно сократить отклонение между заданным и фактическим значением потока и тем самым сообщение не будет появляться.

  Functions 5.12 Safety-related applications 5.12 Safety-related applications 5.12.1 Overview Functional safety Machine components operated by electrical drives are intrinsically hazardous. If a drive is incorrectly used or acts in an unexpected manner in the event of a malfunction, not only can this damage the machine but it can also cause severe injury or death.

  Functions 5.12 Safety-related applications Permissible control modes for using fail-safe functions When the prerequisites mentioned above are fulfilled, the fail-safe functions can be used for both V/f and vector control. Restrictions regarding SLS and SS1 CAUTION Safety functions SS1 and SLS must not be used when the motor can still be accelerated by the mechanical elements of the connected machine component once the frequency converter has been shut down.

  Functions 5.12 Safety-related applications Controlling the safety functions The safety functions in the frequency inverter can be controlled via fail-safe digital inputs as well as over safe bus communication PROFIsafe via PROFIBUS or PROFINET in conjunction with a fail-safe CPU. Safe feedback from the frequency converter When fail-safe functions are used, feedback is generally required as to whether or not the drive is in a safe state.

  Functions 5.12 Safety-related applications 5.12.2 Restoring safety-related parameters to the factory setting Before starting to commission the safety functions, you should know whether the safety- relevant parameters of the frequency inverter have already been changed. If you do not precisely know the setting of the safety-relevant parameters, then reset these parameters to the factory setting.

  Functions 5.12 Safety-related applications 5.12.3 Controlling the safety functions via fail-safe inputs Connecting sensors to fail-safe inputs The fail-safe inputs of the frequency inverter are designed for connecting electromechanical sensors with two NC contacts. It is not possible to directly connect sensors with two NO contacts and antivalent contacts (1 NO contact and 1 NC contact).

  Functions 5.12 Safety-related applications 5.12.4 Settings for the «STO» function Activating fail-safe inputs A fail-safe input of the frequency inverter is activated by assigning it a safety function. This is described in the following using an example. The example shows the assignment of the fail- safe digital input FDI0 to the STO safety function using STARTER.

  Functions 5.12 Safety-related applications Testing the shutdown paths Shutdown paths are circuits used to shut down a motor in a safety-relevant fashion. The shutdown paths must be checked regularly to ensure that the fail-safe frequency inverter complies with certification requirements. In the factory setting, the frequency inverter always checks its shutdown path if the STO function is deselected.

  Functions 5.12 Safety-related applications Reasons for inconsistent input signals With electromechanical sensors (e.g. EMERGENCY STOP buttons or door switches), the contacts may bounce briefly at the moment switching takes place. The two sensor contacts never switch at exactly the same time either. As a result, the frequency converter responds with a fault and indicates signal inconsistencies.
