Where the VFD022M21A fits on the line
The Delta VFD022M21A sits in the VFD-M micro-drive slot aimed at standalone panels driving a 2.2 kW / 3 HP motor from a 230 V single-phase feed — conveyors, small pumps, fans, mixers and packaging-machine sections where a 3-phase supply isn't pulled to the machine. Rated for 3 HP (2.2 kW) of motor output at 230 V class, it covers the small-frame applications the VFD-M series was built around without stepping into the higher-power MS300/CP2000 line. Sensorless vector control on a 10 A continuous output stage means the drive can hold torque at low speed without an encoder — useful on conveyors that stall under load and on small pumps where the starting torque matters more than absolute speed accuracy.
Input side: single-phase 230 V with three-phase tolerance
The input stage is rated Single/3-phase 200-240 VAC at 50/60 Hz, with ± 10% voltage tolerance (180-264 VAC) and ± 5% frequency tolerance (47-63 Hz). The Single/3-phase input current rating is 11.5/7.6 A — the drive accepts either wiring configuration without a hardware change, but if a single-phase model is fed from a 3-phase supply the input draw rises to 27 A, which has to be sized into the branch protection on a single-phase input application. Single-phase 230 V is the version code '21' in the VFD-M suffix — picking the wrong suffix is the most common cross-reference error with this family, so confirm the supply at the panel before specifying the code.
Output side: 10 A continuous, 0.1-400 Hz
The output stage delivers 10 A rated current at 3.8 kVA rated capacity, with a maximum output voltage that tracks the input 1:1 (3-phase proportional to input). Output frequency spans 0.1-400 Hz, covering constant-torque low-speed work down to fractional Hz and high-speed fan or spindle applications up through the standard 400 Hz ceiling. Carrier frequency is adjustable from 1-15 kHz; pushing it up quiets motor acoustics but adds switching loss to the IGBT stage, so the 10 A continuous figure applies at the default carrier and the drive derates as the carrier rises into the audible-noise-sensitive range.
