What is the meaning of frequency conversion resolution
For digitally controlled inverters, even if the frequency command is an analog signal, the output frequency is given in steps. The smallest unit of this level difference is called the frequency conversion resolution. The frequency conversion resolution is usually 0.015~0.5Hz. For example, if the resolution is 0.5Hz, then the upper part of 23Hz can be changed to 23.5 and 24.0 Hz, so the action of the motor is also followed in steps. This poses a problem for applications like continuous coil control. In this case, if the resolution is about 0.015Hz, it can be adequately adapted to a level difference of 1 r/min or less for a 4-level motor. In addition, the given resolution of some models is not the same as the output resolution.
