asynchronous serial output TX connects to the FT232R’s asynchronous serial input RXD , and the FT232R’s asynchronous serial output TXD connects to the PIC18F4520’s asynchronous serial input RX . The example circuit uses the RTS# and CTS# handshaking lines on the FT232R. These lines can connect to any otherwise unused port pins on the PIC18F4520. If needed, the FT232R’s other status and control pins can connect to other port pins on the PIC18F4520. Attach the USB connector to a port on a PC and follow the on-screen instructions to install FTDI’s drivers. See FTDI’s website for a detailed driver-installation guide. When the drivers are installed, the Device Manager shows a new COM port, and the port is ready for use. In a similar way, any microcontroller with an asynchronous serial port and additional port pins if needed can interface to an FT232R and function as a USB virtual COM port. 331 Chapter 15 Converting from RS-232 to USB If you have an existing design that uses RS-232, an FT232R chip can quickly convert the design to USB. Figure 15-5 shows a circuit that uses RS-232 along with the same circuit converted to use USB. In the RS-232 circuit, microcontroller pins connect to a MAX237 interface chip that converts between TTL and RS-232 logic levels. The example circuit includes the asynchronous serial interface TX and RX plus six generic I/O pins to support RS-232’s status and control signals. A circuit that doesn’t use all of the status and control signals requires fewer drivers and receivers. The schematic doesn’t show the MAX237’s capacitors or power and ground connections. In the USB circuit, the microcontroller port pins connect to the corresponding pins on an FT232R USB UART. Instead of an RS-232 connector, the circuit has a USB connector that interfaces to the FT232R. The pins for any unimplemented signals can remain open on the FT232R or can be tied to a desired state. In most cases, a circuit modified in this way requires no changes to device f prom-electric.ru

Здравствуйте!
Показывается неисправность err59 на частотном регуляторе M600-03400045A. Похожие устройства ATV71PU40N4Z, CIMRE7Z21P51B, CSX-055-V4-C1 на насосах функционируют.
Методику нашел через яндекс по запросу "Ремонт частотного преобразователя Delta VFD1600F43A" prom-electric.ru/articles/1/225/ . Вышел из строя датчик Холла.
Пока!

Добрый день!
Выпадает авария al135 на частотнике FR-E520-2.2K-NA. Другие устройства ATV71HC50Y, CIMR-F7C41320, GP102075-9 установленные на вентиляции работают исправно.
Решение нашел через майлру по запросу "Ремонт частотного преобразователя Altivar 71 plus atv71exs5c31n" prom-electric.ru/articles/1/880/ . Неиcправен был БП и обвязка.
Успехов!
