What are the differences and advantages between vector control and V/F control in frequency converters? The load used in our facility is a belt-driven reducer, with a scraper attached to it for removing powder. Initially, we used a domestic frequency converter; at a frequency of 15 Hz, the material was discharged properly without any issues such as blockages or trips of the frequency converter. After that frequency converter developed problems, we replaced it with an ABB 510 frequency converter, and now the operating frequency is 23 Hz – yet blockages still occur, leading to trips of the frequency converter. What is the reason for the inquiry? How should this be solved?
Use a clamp meter to check the current changes; it’s not necessarily related to the inverter, and blockages can also occur if the materials are of poor quality.
ABB 510 requires DTC direct torque control
