How can I learn the converter well?
If you are engaged in maintenance or after sale, you must know the main circuit diagram of the converter, rectifier, filter, inverter. Some electronic components must know, from the main circuit is frequently such as varistors, charging resistance, pressure resistance, no sense of capacitor, filter capacitor, driving circuit of multiple optocoupler such as 2503503120316, this is referred to as the optocoupler and the role, you must know the pin. Because the maintenance process should always be to determine the quality of the device.
Frequency converter this thing, in fact, still very practical, so can go to customers to install and debug, is a shortcut to quickly learn the frequency converter. In the installation of debugging, you can take time to read several times the frequency converter manual, and if you can discuss with technical support, I believe you will soon enter the role.
1. overload or acceleration and deceleration in case of braking resistance to increase, to help the loss of mechanical energy, you may have to set the corresponding parameters. 2. inverter motor with a little weak, if there is an advanced mode (magnetic flux vector control and the like), enable this function can play a maximum motor ability (the specific reference manual, cheap converter is not it) 3. serial communication change frequency, need to understand the communication protocol converter, usually have instructions to write specific parameters of frequency message reference manual.
Frequency converter training teacher suggested: Theory + practice combinedTheory: understand the frequency converter each parameter meaning, the frequency changer principle, the control way, the instruction manual, the approximate operation, knows how the matterPractice: combined with some special requirements of practice to do the debugging, this needs the accumulation of experience
Secondly, you can also take part in some frequency converter, PLC training institutions, in order to improve themselves, through training to enhance their skills, this is a way to quickly learn.
