Connecting Inverters’ PU Interface to Computers with RS-232C Interface Since most computers do not come with RS-485 interfaces, and many computers are equipped with RS-232C interfaces (serial ports, also known as COM ports), an RS-232C to RS-485 interface converter can be used to connect computers with RS-232C interfaces to the PU interface.
Troubleshooting Inverter Circuit Boards Generally speaking, the printed circuit boards on an inverter mainly include the drive board, main control board, and display board. The factors affecting the lifespan of the inverter’s printed circuit boards include the lifespan characteristics of the smoothing capacitors in the power supply section and the buffer capacitors in the IPM … Read more

I remember when I first joined the industry, I took over a project to upgrade an injection molding machine. The communication between the inverter and the PLC was always intermittent. After several days of troubleshooting, I discovered that the grounding was not done correctly, which caused interference. Today, I will share my experiences and techniques … Read more
Search on WeChat Technical Training The PLC and the inverter have a relationship of inclusion and being included. Both can execute specific commands to control electric motors. The PLC is a hardware device for program input execution, while the inverter is one of them. However, the scope of the PLC is broader than that of … Read more
The relationship between PLC and inverter is one of inclusion, where both can execute specific commands to control electric motors. The PLC is a programmable hardware for executing programs, while the inverter is one of the devices it can control. However, the PLC’s scope is broader than that of the inverter, enabling it to control … Read more

In a previous project, I was involved in the communication between the Yaskawa inverter and the S7-300. However, the available materials at night were all about control words and status words to control the inverter’s start and stop, as well as read some basic parameters. What I needed was to modify the inverter’s parameter values … Read more
