Delta VFD-VE Drives: Model Selection and Feedback Requirements
Delta VFD-VE supports several motor-control modes, including encoder-feedback options. Match the drive and feedback hardware to the control method your machine requires.

- VFD110V23A-2
- VFD150V43A-2
For a Delta VFD-VE purchase, the selected control method determines whether encoder-feedback hardware belongs in the specification. WOOLARS supplies VFD-VE AC drives; this page explains that distinction and lists three complete model references for purchasing.
Which VFD-VE control modes use encoder feedback?
Delta’s manual lists five selections under control-method parameter 00-10:
| Control mode | Encoder feedback in this mode |
|---|---|
| V/f | No |
| V/f + encoder (VFPG) | Yes |
| Sensorless vector control (SVC) | No |
| FOC vector control + encoder (FOCPG) | Yes |
| Torque control + encoder (TQCPG) | Yes |
For purchasing, this separates a drive requirement from a feedback-system requirement. An existing FOCPG application needs its encoder and PG-card specification preserved in the replacement scope. The series name alone does not identify those fitted components.
A PG card must match the encoder interface
Delta’s VFD-VE encoder feedback guidance distinguishes open-collector and line-driver interfaces and requires the correct encoder voltage, pulses per revolution and pulse format. These are separate matching conditions.
For example, an encoder description containing only “1,024 pulses” leaves its electrical interface and supply unresolved. Identify those fields from the encoder documentation, then check the corresponding PG-card specification. Delta’s published example is one configuration, not a universal setting for every machine.
The VFD-VE manual lists EMV-PG01X, EMV-PG01O and EMV-PG01L as PG-card options for its feedback-control procedure. Their presence in the same list does not make them interchangeable.
Three VFD-VE ordering references
| Complete model | Manual frame | Terminal-reference page |
|---|---|---|
| VFD075V43A-2 | C | 2-10 |
| VFD110V23A-2 | D | 2-11 |
| VFD150V43A-2 | D | 2-11 |
These frame references locate the applicable main-circuit terminal information. They do not describe the fitted encoder card or establish the drive’s complete application rating. Keep the original code, including its suffix, on the purchase order.

Use the manual for the installed configuration
The Delta VFD-VE manual used here is revision April 2016, 07VE, SW V2.05. Section 3.3.2.3 explains feedback-control preparation; Appendix B covers PG cards. Delta also provides an official PG-card and encoder setup explanation.
These references help identify the required components. Actual parameter values and commissioning must follow the installed motor, encoder, drive software and machine requirements.
