What is the principle of a speed control switch? How do I adjust the motor speed? How does the speed control switch adjust the frequency of the inverter in order to control the motor speed?

The core component for speed control is the frequency converter, while the speed control switch is a control element that adjusts the amplitude of the signal, which is then sent to the frequency converter to adjust the frequency and thus the speed.

What signal does the speed control switch output?
Reply #42017-04-04
It could be a 4-20mA DC signal, or a 1-5V DC signal; it depends on what type of input signal the frequency converter requires
