Привет всем!
Горит error w027 на частотнике FR-F720-01870-NA. Похожие приборы ATV71EXC5C20Y, CIMRF7Z20751B, SMC930030 -p установленные на экструдерах работают исправно.
Решение нашел через яндекс по запросу "bf904" prom-electric.ru/media/BF904_904R_N.pdf . Оказалось сгорел фильтр помех.
Всего хорошего!

Здравствуйте!
Светится авария w142 на частотном приводе M700-09402240E. Другие приборы ATV71H075N4383, VZA4015FAA-S5030, VFD900C43A установленные на компрессорах без ошибок.
Решение нашел через гугл по запросу "buk7y25-80e" prom-electric.ru/media/BUK7Y25-80E.pdf . Поменял позистор.
Всем удачи!

Бодрого дня!
Выпадает авария f224 на частотном приводе FR-V220E-2.2K. Похожие устройства ATV61WU55N4U, CIMRE7Z20111A, L300P-022LBRM установленные на насосах в порядке.
Решение нашел через яндекс по запросу "buk7507-30b" prom-electric.ru/media/BUK7507-30B.pdf . Оказался неисправен ограничительный резистор.
Всем успехов!

Приветствую Вас!
Горит ошибка err14 на частотном преобразователе M800-09402240A. Похожие приборы ATV71WD18N4, CIMR-VC4A0002BAA-1000, CIMR-V7SC27P50 установленные на насосах без неисправностей.
Описание нашел через google по запросу "Ремонт частотного преобразователя Altivar 11 atv11hu05m3u" prom-electric.ru/articles/1/988/ . Заменил полевой транзистор.
До свидания!Удачи!

enables in-line signaling to a microcontroller or other device that has no input buffers or flow-control lines. The signal also provides a way to toggle the TX line as desired for any purpose. Shield Ground In the 25-pin connector, pin 1 is a shield connection to allow grounding of a cable shield. The pin isn’t always connected inside the device, and the 9-pin connector doesn’t include the pin. Many shields instead use the connector shell to connect to a grounded chassis. The shield normally connects to the chassis, r frame, of the DTE only, not the DCE. Earlier versions of the standard called pin 1 protective ground, and the wire sometimes connected the chassis of the equipment on both ends. Each chassis in turn connected to a safety ground at the equipment’s power plug. TIA-232 recommends using a separate wire not one of the wires in the connector to connect the grounds of the two chassis if needed. Voltages RS-232 logic levels are defined as positive and negative voltages rather than the positive-only voltages of TTL and CMOS logic Table 4-2 . At an RS-232 data output TX , logic 0 is defined as equal to or more positive than +5V, and logic 1 is defined as equal to or more negative than -5V. In other words, the data uses negative logic, where the more positive voltage is logic 0 and the more negative voltage is logic 1. 46 Inside RS-232 Table 4-2: RS-232 uses positive and negative voltages. Parameter Voltage V Logic 0 or On output +5 to +15 Logic 1 or Off output -5 to -15 Logic 0 or On input +3 to +15V Logic 1 of Off input -3 to -15 The status and control signals use the same voltages, but with positive logic. A positive voltage indicates a logic 1 and a function that is On, asserted, or True, and a negative voltage indicates a logic 0 and a function that is Off, not asserted, or False. An RS-232 interface chip typically inverts the signals and converts between TTL/CMOS voltages and RS-232 voltages. On a UART’s output pin, a logic-1 data bit or an Off contro prom-electric.ru
