Вот посмотрите тут по ошибке OU на 14 стр.

Рядом с того же распределительного щита другие станки с более капризными  , на мой взгляд приводами спокойно работают . Да и этот станок работал долго ,

и сейчас на малых оборотах оборотах работает .

Видел такое на одном объекте. Причиной такого поведения так была электропечь

Тоже видел . Мегаваттная дуговая плавильная печь при включении заставляла зависнуть стойки ЧПУ и мигнуть лампы ДРЛ в корпусе вспомогательных цехов . 

Частотников тогда в зоне обслуживания ещё не было , даже 16К20 Ф3 с «Размерами» в цеху уже не было . Контролировать напряжение в звене постоянного 

напряжения (тока ) за блоками электролитов запоминающим осциллографом не мог (его тоже не было ). Не тот случай .

Снял ПЧ..Банки электролитов по визуальному осмотру без вздутий и протечек . Поставили неудачно — этикетками так , что не увидишь без разборки . Ни ёмкость ,

ни год изготовления . Сговорился со старым (чуть более молодым по возрасту) коллегой с той промплощадки , что он берёт ПЧ на разборку с ревизией .

Пайки по импортной электронике — его хлеб .  Да и сможет три фазы подать и на левый асинхронник нагрузить .По итогам ревизий , перепаек ,установок  и

повторных снятий ПЧ или забраковки по ремонтонепригодности  — обязательно отпишусь . Ещё раз — рад всем мнениям . Всех с праздниками — Днём взятия

To perform initialization, press the and keys
together to set 1, then press the key. The set

When the inverter protective function which invokes the

retry operation is activated, this function releases
operation of the protective function and restarts
operation without issuing an alarm or terminating output.

Set the protective function release count and waiting
time from its operation startup to release.
Setting range (Count) : 0, 1 to 10

(Waiting time) : 2 to 20 seconds

To not use the retry function, set 0 to «H04 Retry (count).»

When the value of «H04 Retry (count),» is set from 1 to
10, an inverter run command is immediately entered
following the wait time set in H05, «Retry (wait time),»
and the startup of the retry operation. If the cause of
the alarm has been removed at this time, the inverter
starts without switching to alarm mode. If the cause of
the alarm still remains, the protective function is
reactivated according to the wait time set in «H05 Retry
(waiting time).» This operation is repeated until the
cause of the alarm is removed. The restart operation
switches to alarm mode when the retry count exceeds
the value set in «H04 Retry (count).»
The operation of the retry function can be monitored
from terminals Y1 to Y5.

WARNING

When the retry function is selected,
operation automatically restarts depending
on the cause of the trip stop. (The
machine should be designed to ensure
safety during a restart)
as accident may result.

This function specifies whether cooling fan ON/OFF
control is automatic. While power is applied to the
inverter, the automatic fan control detects the
temperature of the cooling fan in the inverter and turns
the fan on or off.
When this control is not selected, the cooling fan rotates
continually.
