22C-D017N103 — VFD-C Series AC Drive, 480V Three-Phase, 7.5 kW, IP30

The 22C-D017N103 is a general-purpose variable frequency drive from the 22C series, rated at 7.5 kW / 10 HP with 17A output current for 380–480V AC three-phase input. The IP30 / NEMA 1 enclosure adds a top cover for open-rack or semi-exposed mounting. It supports V/Hz and sensorless vector control, includes a DSI RS-485 port, and accepts communication and encoder option cards through its peripheral port. At 7.5 kW, this drive covers pumps, fans, conveyors, and compressors in the mid-power industrial range.

7.5 kW in the 22C — Application Fit

The 22C series sits above the 22A in the general-purpose drive hierarchy, designed for higher power ratings while maintaining the same option card architecture. At 17A / 7.5 kW, this drive serves centrifugal pumps and fans in the 5–10 HP class, conveyor drives with moderate inertia, and HVAC equipment where variable speed delivers meaningful energy savings over across-the-line operation.

Two analog inputs are available — one for a speed reference signal, one configurable as a process feedback for the drive's onboard PID loop. This allows the drive to close a simple pressure or flow control loop independently without a PLC PID instruction. Set the feedback input to the measured variable (pressure sensor output, flow meter), the reference input or a parameter to the setpoint, and the drive adjusts its output frequency to maintain the process variable. For single-loop standalone applications, this eliminates a layer of control system complexity.

Thermal and Panel Design at 7.5 kW

At 17A output, the drive dissipates approximately 150–200W at full load. In a sealed panel without active cooling, heat accumulates quickly. Key installation considerations:

Maintain minimum 100 mm clearance above and below the drive for cooling airflow.
Derate begins at 40°C ambient — approximately 1–2% per degree Celsius above 40°C. A summer panel interior at 45°C means 5–10% less available output current.
Motor cable: keep under 30 m. At longer runs, reflected wave voltage at motor terminals stresses motor insulation — add a dV/dt output reactor.
Input fusing: use semiconductor-rated fuses or a properly-rated circuit breaker per drive on its own dedicated circuit.
For tight panel thermal budgets, a smaller switching frequency (2 kHz vs default 4 kHz) reduces drive losses by 15–20% at the cost of slightly higher motor acoustic noise.

FAQ

Q: Is an input line reactor recommended at this power level?

Yes, especially on stiff supplies with low source impedance or where multiple drives share the same transformer. A 1.5–3% line reactor reduces input harmonic distortion and protects the rectifier from voltage transients. At 7.5 kW in an industrial panel, it's straightforward to include and eliminates a category of potential failures.

Q: Can EtherNet/IP or DeviceNet be added via the option port?

Yes. The 22C peripheral port accepts 22-series communication option cards including 22-COMM-E (EtherNet/IP) and 22-COMM-D (DeviceNet). Install the appropriate card to add network control and monitoring without changing the drive.

Q: What autotune is required before running SVC mode?

Static autotune with the motor at rest — enter accurate motor nameplate data first (rated voltage, current, frequency, speed, and power), then run the autotune routine. The drive measures stator resistance and inductance to calibrate its torque model. Rotating autotune with the load decoupled gives better results where practical.

Q: Can the onboard PID function handle both temperature and pressure control simultaneously?

No. The 22C includes a single PID loop that controls one process variable. For multi-variable control, a PLC-based PID that sends a speed command to the drive via analog output or network is the appropriate architecture.
