HDS03.2-W100N-HS70-01-FW

Does the HDS03.2-W100N-HS70-01-FW need a separate power supply or can it run standalone?

It operates on a shared DC bus from an HVE/HVR supply module; plan the cabinet around L+ / L− connections and the drive’s short-circuit and fuse requirements. Typical W100N variants expect ~530–670 VDC bus and 500 VAC max output, so size upstream protection accordingly.

What cabinet layout keeps the internal blower effective?

When stacking drives vertically, install a baffle between rows so upper blowers don’t ingest lower exhaust; otherwise performance drops and overheating risk rises. Route cooling air so the unit doesn’t recirculate warm air and avoid condensation from cooling units.

Does switching frequency change how much continuous current the drive can deliver?

Yes continuous current capability drops as PWM frequency increases; W100N variants list ~50 A at 4 kHz versus ~35 A at 8 kHz. Plan thermal margins and motor sizing with that derating in mind.

How should I route motor and signal wiring to minimize EMI issues?

Separate signal from power runs, use shielded lines for analog/encoder signals, and terminate shields on the provided grounding/mounting hardware. Follow the supplied connector kit and torque specs to maintain EMC and safety.

Is this platform suitable for high-speed spindles or only axes?

W100N models support output frequencies up to ~1000 Hz, enabling high electrical speeds when matched to appropriate motors. Ensure motor voltage/frequency are within limits and that bus and cooling are sized for the duty cycle.
