22A-D4P0N104 — VFD-A Series AC Drive, 480V Three-Phase, 1.5 kW, 4.0A

The 22A-D4P0N104 is a general-purpose AC drive from the 22A series, rated at 1.5 kW / 2 HP with 4.0A output current for 380–480V AC three-phase input. It supports V/Hz and sensorless vector control, includes DSI RS-485 communication as standard, and accepts communication option cards through its peripheral option port — DeviceNet, EtherNet/IP, and others. IP20 open-type housing for panel mounting.

The 22A series occupies the mid-tier of general-purpose drives between the V-mini and the 22B/755 platforms. At 1.5 kW on 480V, it handles small conveyor sections, pump drives, agitators, and fans where a basic V-mini wouldn't serve and a 755 would be over-specified.

Drive Setup and Control Options

The five digital inputs default to run forward, run reverse, stop, fault reset, and a spare programmable input. All five are reconfigurable via the drive's parameter set to other functions including jog, speed preset selection, and external fault. The analog input accepts both 0–10V and 4–20 mA — a jumper on the control board selects the mode. Verify the jumper position matches the signal source before commissioning; a voltage signal on a current-mode input (or vice versa) reads incorrectly without generating a fault, making it easy to miss during testing.

For PLC-integrated installations without fieldbus, the analog input provides the speed reference and the digital inputs handle start/stop. For networked installations, the DSI port connects the drive to other DSI-capable devices on a shared serial bus, or a 22-COMM-E card in the option port adds full EtherNet/IP capability. Autotune is required before running SVC mode — enter motor nameplate data accurately first.

Installation Notes

Mount vertically on DIN rail or panel surface. Minimum 50 mm clearance above and below for airflow.
Motor cable length: keep under 30 m. Add a dV/dt reactor for longer runs.
Input protection: dedicated circuit breaker per drive, sized for input current — not shared with other loads.
Dynamic braking: an internal DB transistor is fitted; external resistor required for fast deceleration or high-inertia loads.

FAQ

Q: Can EtherNet/IP be added to this drive without replacing it?

Yes. Install a 22-COMM-E option card into the drive's peripheral port. The card adds a full EtherNet/IP interface with cyclic I/O and explicit messaging capability without any other hardware change.

Q: Does SVC require an encoder?

No. Sensorless vector estimates rotor speed from current and voltage measurements — no feedback device needed. For closed-loop vector with full torque accuracy at near-zero speed, an encoder card is required.

Q: What happens if a 4–20 mA signal is wired to the analog input when the jumper is set for 0–10V?

The drive reads the voltage developed across its input impedance by the 4–20 mA source — typically a low value, resulting in near-zero speed command at 4 mA and about 50% speed at 20 mA rather than the expected 0–100% span. No fault is generated. Always verify jumper position matches the signal type before commissioning.

Q: Can the relay output signal when the drive is at target speed?

Yes. Configure the relay output function parameter to "At Speed" — the relay energizes when output frequency reaches the commanded setpoint within the configured deviation band.
