デルタ VFD450C43S-00 – Key Selection Notes (Field Version)
- 力 & ロードマッチング
This drive is Heavy Duty (HD): 45kW/91A, 150%/60s overload for extruders, クレーン, 破砕機, 工作機械.
Fans/pumps can be used as SHD 60kW, but oversizing is not recommended.
For shock loads (プレス機, 破砕機), oversize by one power level or verify overload margin.
- 電圧 & Grid
3-phase 380–480V input, 50/60Hzユニバーサル.
For unstable or high-harmonic grids: DC reactor is built-in, but an input AC reactor is still recommended.
- モーターの互換性
Supports induction / PMSM / SynRM in three drive modes.
Auto-tuning is mandatory for PMSM; otherwise torque and speed will be unstable.
- 制動 & Stopping (致命的)
VFD450C43S-00 has NO built-in brake unit!
For fast stopping or overhauling loads (クレーン, エレベーター, downhill conveyors):
External brake unit + resistor is required.
推奨: Delta DBU-4055 brake unit.
- インストール, 冷却 & 保護
Must be mounted vertically with ≥100mm ventilation space top and bottom.
Derate when ambient > 40℃ (≈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 (センサー, PLC): add external EMC filter + シールドケーブル + proper grounding.
- 安全性
This model does NOT include STO (安全トルクオフ).
For safety-related applications (ホイスト, machines), use STO-equipped model (-01 サフィックス) or external safety relay.
- コミュニケーション & 拡大
Standard only Modbus RTU.
プロフィネット / EtherCAT / EtherNet/IP require optional communication card.
- スペアパーツ & メンテナンス
Recommended spares: 冷却ファン, コンデンサ, brake resistor.
Use keypad parameter copy for fast commissioning of multiple drives.
