Delta VFD450C43S-00 – Key Selection Notes (Field Version)
- Leistung & Lastabgleich
This drive is Heavy Duty (HD): 45kW/91A, 150%/60s overload for extruders, cranes, Brecher, Werkzeugmaschinen.
Fans/pumps can be used as SHD 60kW, but oversizing is not recommended.
For shock loads (presses, Brecher), oversize by one power level or verify overload margin.
- Stromspannung & Grid
3-phase 380–480V input, 50/60Hz universal.
For unstable or high-harmonic grids: DC reactor is built-in, but an input AC reactor is still recommended.
- Motor Compatibility
Supports induction / PMSM / SynRM in three drive modes.
Auto-tuning is mandatory for PMSM; otherwise torque and speed will be unstable.
- Bremsen & Stopping (Critical)
VFD450C43S-00 has NO built-in brake unit!
For fast stopping or overhauling loads (cranes, Aufzüge, downhill conveyors):
External brake unit + resistor is required.
Empfohlen: Delta DBU-4055 brake unit.
- Installation, Cooling & Protection
Must be mounted vertically with ≥100mm ventilation space top and bottom.
Derate when ambient > 40°C (≈1% per °C).
Unit is IP20 open type; use enclosure or IP54 kit in dust, moisture or oil.
- EMC
-00 version has NO built-in EMC filter.
For sensitive devices (sensors, SPS): add external EMC filter + shielded cable + proper grounding.
- Sicherheit
This model does NOT include STO (Sicher abgeschaltetes Drehmoment).
For safety-related applications (hoists, machines), use STO-equipped model (-01 suffix) or external safety relay.
- Communication & Expansion
Standard only Modbus RTU.
PROFINET / EtherCAT / EtherNet/IP require optional communication card.
- Spare Parts & Wartung
Recommended spares: cooling fan, Kondensatoren, brake resistor.
Use keypad parameter copy for fast commissioning of multiple drives.
