DriveCore DC-15 AC Drive
15 kW variable-frequency drive · IP20 panel mount
The DC-15 is a 15 kW variable-frequency drive for three-phase motors. This manual covers the fan and capacitor service, the module-level repairs and the spare parts, for trained service staff working to the safety warnings below.
Danger
Lethal voltage: wait to dischargeThe DC link holds a lethal charge after power-off. Isolate, lock off, wait ten minutes and confirm below 50 V at the DC terminals before touching any component. Service by trained personnel only.
Tools & materials
| Tool | Spec | Notes |
|---|---|---|
| Insulated screwdriver set | 1000 V VDE | Torx and slotted |
| DC-link voltmeter | 0–1000 V DC | Confirm discharge < 50 V |
| Torque wrench | 2–20 N·m | Terminal and busbar torque |
| ESD wrist strap | 1 MΩ | Control-board handling |
| Thermal paste | Non-silicone | IGBT module reseat |
Fan & capacitor service
- Isolate the supply, lock off and wait ten minutes for the DC link to discharge.
- Confirm the DC-link voltage is below 50 V at the +/− terminals before touching anything.
- Record the parameter set, then remove the control board on its ESD strap.
- Replace the cooling fan or capacitor bank as required, observing polarity and torque.
- Reseat the control board, reload the parameters and re-torque all power terminals.
- Run the drive uncoupled and confirm no fault codes before returning to service.
