Здравствуйте! Скажите, пожалуйста, почему ошибка A7 C1 может возникать на частотном преобразователе ABB acs880 при переключении на управление шиной Profibus? Модуль используется FPBA-01, и зеленый индикатор «модуль» (нет связи с этим узлом) постоянно мигает на нем. Подключен к процессору Siemens 317 2 PN / DP PLC. Диагностика привода на шаге 7 показывает, что привод находится в состоянии «ОК».
Welcome to you, I would like to ask you to write in English so that all the colleagues who read can give you their help.For your request, there is probably an error in the programming, you will find in the ABB library some programming examples in ProfiBus, also remember that after each variation of the parametric groups related to the fieldbus, you must always refresh with parameter 51.27.
Hello! Please tell us why the A7 C1 error can occur on the ABB acs880 frequency Converter when switching to Profibus bus control? The module is used by the FPBA-01, and the green "module" indicator is constantly flashing on it. Connected to a Siemens 317 2 PN / DP PLC processor. Diagnostics of the drive in step 7 shows that the drive is in the " OK " state.
The fact is THAT the acs880 drive was installed instead of the ACS800. On a known good Profibus network. Is it necessary to change anything in the program when replacing the drive?
The GSD file was downloaded for the FPBA-01 module. The file was downloaded from the ABB website. Telegram this uses PPO 3. The profile of the selected ABB driver. The corresponding profile is also selected in the GSD file settings. On the Profibus network, we only need to control the speed. The drive starts with a discrete signal (button) and then switches to Profibus control by the operator. The drive is configured as described in the manual. But when switching to Profibus, it returns an a7c1 error. At the same time, there are only 18 ABB ACS800 drives in the network. Everything works except the new ACS880. At the same time, after the drive is started, we see its actual state (speed) on the PLC. But when switching to Profibus network management, an error occurs immediately.
