This is an installation, parameter setting, troubleshooting and daily maintenance manual for delta vfd-b series ac motor drives.
This manual covers the Delta VFD‑B Series variable‑frequency drives used to control 3‑phase induction motors. It includes safety warnings, preparation steps, and detailed instructions for installing and wiring the drive.
Key sections include installation and wiring diagrams, start‑up procedures, digital keypad operation, parameter configuration, fault codes, troubleshooting, and full specifications of the drive series. Appendices list accessories, specifications, and guidance for selecting the appropriate motor drive for a given application.
| Max. Applicable Motor Output (kW) | 0.75 – 75 (depending on model) |
|---|---|
| Rated Output Current (A) | 5.0 – 145 (depending on model) |
| Output Frequency Range | 0.1 – 400 Hz |
| Cooling Method | Natural Fan Cooled |
| Weight (kg) | 2.7 – 50 (depending on voltage class) |
Disconnect AC input power before any wiring, wait ten minutes for DC‑link capacitors to discharge, and ground the VFD‑B using the ground terminal.
The rated voltage must be ≤ 240 V (≤ 480 V for 460 V models, ≤ 600 V for 575 V models).
The VFD‑B series is intended only for 3‑phase induction motors; it cannot be used with single‑phase motors or for other purposes.
