Вечер добрый!
Выпала неисправность er120 на преобразователе FR-A220-3.7K-UL. Подобные приборы ATV312HU15N4, CIMR M5N 25P5, IMS20088-V5-C24-F1-E4 установленные на двигателях работают.
Описание нашел через yandex по запросу "nx3008pbk" prom-electric.ru/media/NX3008PBK.pdf . Оказался неисправен PWM контроллер.
Пока!

for an embedded system’s microcontroller. The code examples are for Microchip Technology’s PIC18F4520, with each example provided for both microEngineering Labs, Inc.’s PICBASIC PRO compiler and Microchip’s MPLAB C18 C compiler. The concepts and much of the code are portable to other chip architectures and compilers. A Microcontroller Serial Port Microchip’s PIC microcontrollers are inexpensive, widely available, and include variants to suit a range of applications. Many of the chips have hardware support for asynchronous serial communications. Other microcontrollers support serial ports as well. The details vary, but support typically consists of a hardware UART or USART with a series of registers to configure the port, monitor events, and store received data and data to send. 229 Chapter 11 Compilers often provide library functions that simplify accessing the port hardware. About the PIC18F4520 The PIC18F4520 has an 8-bit data bus, 32 kilobytes KB of flash memory for program storage, and 1.5 KB of RAM and 256 bytes of EEPROM for data storage. The power supply can range from +4.2V to +5.5V. The PIC18LF4520 variant can use a power supply as low as +2V. For serial communications, the chip contains an enhanced USART EUSART that supports asynchronous and synchronous serial communications. Other on-chip functions include four timers, a 10-bit analog-to-digital converter with up to 13 channels, an analog comparator, and two modules that can perform capture, compare, and pulse-width-modulation PWM functions. The 40/44-pin versions also have an 8-bit parallel port. Most of the chips’ I/O pins have assigned functions, such as serial-port input and output, but the pins can have other uses if firmware isn’t using the assigned functions. Other chips in the PIC18F4520 series have different combinations of functions and package options. The data sheet for the series has complete documentation for the chips. The Enhanced UART The PIC18F4520’s EUSART supports using either an prom-electric.ru
