The VFD first rectifies the input AC power to the DC bus. The VFD then inverts from DC back to AC power at the required electrical frequency to drive the motor at the desired speed. The output frequency from the drive can range from 0 to 60 Hz, or even higher frequencies. Because the output waveform is no longer a pure sine wave, torque ripple. Oct 23, 2014 · V/f’s speed control range is 1:40. Multiplying this ratio by the maximum frequency determines the VFD’s minimum running speed at which it can control the motor. For example, with a 60-Hz .... It reached max frequency at approximately the same position. I checked the voltage in this "dead zone" and it did adjust down from 10.5v. The built in pot does adjust from 0 to 100 hz using the full range. Is it possible the VFD is looking for a max of 10v, so when the pot reaches 10v at a slightly lower position, it assumes that's the max. Typical manufacturers’ derating guidelines suggest using the base frequency to maximum frequency ratio for speeds up to 90 hertz. At speeds above 90 hertz, the square of the ratio is often used. End users should check with their manufacturer before operating a motor above its base speed. The VFD needs this data to trigger excessive load alarms or trips in case of thermal overload. The VFD must then be programmed with the minimum and maximum speed, while following the guidelines of the safe speed range identified on the motor nameplate. Most VFDs also allow you to set up control strategies for starting, stopping and speed.

If the frequency is so low (0.1 Hz for example) that each phase switch will remain on for its portion of the waveform - this phase's switching devices will overheat (for normal and even very large water-cooled VFDs).. Frequency. 50/60 Hz. Enclosure Rating. IP20. VFC 3610 is an enhancement solution for small machinery application as well as other V/f application. With the power output range of 0.422 kW, start-up torque of 1.5 Hz/100 % and 3 Hz/150 %, Heavy-duty/ Normal duty etc. features, VFC 3610 is widely used in fan, water pump, materials transmission. Lower peak current enables the motor to run cooler and develop more torque-producing current throughout the speed range. Mollom VFD 220V 7.5KW 10HP Single Phase Input to 3 Phase 0-999Hz Output Variable Frequency Drive Vector Control Inverter for Spindle Motor CNC Speed Control (Support 3 Phase Input) Single Phase to 3 Phase Converter, My-PS-7.5.
