22B-D1P4N104 VFD 40 Series AC Drive — 0.4 kW / 0.5 HP, 380–480V AC Three-Phase, RS-485 DSI

The 22B-D1P4N104 is a 40 Series AC drive rated at 0.4 kW (0.5 HP), designed for 380–480V AC three-phase input with 1.4A output current. Built around V/Hz and sensorless vector control, it's a compact, reliable choice for general-purpose motor drive applications where simplicity and panel space both matter.

Communication options are available through plug-in option cards — RS-485 DSI is native, with DeviceNet, EtherNet/IP, and other protocols accessible via the drive's option port. Local parameter access uses a 22-HIM-A3 or 22-HIM-C2S keypad. The drive ships in an IP20 open-type enclosure ready for panel mounting.

Application Scenarios

General-Purpose Machine Automation

Packaging lines, assembly machines, and simple material handling systems with small three-phase motors use this drive extensively. The DSI port lets it share a bus with other compatible drives, all controlled from a single master device.

Pump and Fan Drives

Three-phase pump and fan motors in light industrial and commercial systems run efficiently under V/Hz control. An analog input from a pressure or temperature sensor connects directly to the drive for closed-loop process control.

HVAC Equipment

Air handling units, cooling tower fans, and chilled water pump drives benefit from variable-speed operation. Preset speed parameters allow simple multi-step scheduling without network control in standalone installations.

Food and Beverage Processing

Mixer drives, screw conveyors, and dosing pump applications use the compact form factor to mount close to the driven equipment. Speed reference from a PLC analog output connects via the 0–10V input.

Installation Notes

Panel mounting: secure to back panel with four mounting holes. Maintain 50 mm clearance top and bottom; 10 mm minimum side clearance between adjacent drives.
Input fusing: use semiconductor-rated fuses or a circuit breaker on the input lines — the drive has no internal branch circuit protection.
Motor cable: keep cable length to 30 m or less. Above 30 m, a dV/dt filter or output reactor is recommended to protect motor insulation from reflected wave voltage.
Dynamic braking: connect a braking resistor to the DB+ and R terminals for short deceleration times. The internal transistor is active; the resistor is external and must be sized for the application.
Grounding: connect the PE terminal to the panel chassis earth. Floating installations cause erratic behavior and increased EMI.

FAQ

Q: Can the 22B-D1P4N104 run on 208V or 240V three-phase input?

No. The input range is 380–480V AC three-phase. Operating below 380V will cause undervoltage faults. A different catalog number rated for lower input voltage is required for 208/240V systems.

Q: How do I add EtherNet/IP communication to this drive?

Install a 22-COMM-E option card into the drive's comm port. It adds an RJ-45 EtherNet/IP port and allows control and monitoring from a PLC or SCADA system over EtherNet/IP.

Q: What is the DSI port used for?

DSI (Drive Serial Interface) is an RS-485 protocol for networking multiple 40 Series drives on a single cable, controlled from a peripheral device or HIM. It's practical in multi-drive setups where a full fieldbus isn't needed.

Q: Can I use a standard PTC motor thermistor with this drive?

Yes. Wire the PTC sensor to the thermistor input terminals and configure the motor protection parameters in the drive to enable overtemperature fault response.
