User manual for Delta EMF-APP01 phase detection card, covering functions, wiring, installation and setup steps.
The Delta EMF-APP01 phase detection card is used with VFD‑F‑EPS control boards to synchronize the input and output phases of a variable‑frequency drive. It processes two input phases (R, S, T) and provides a processed signal to the control board’s AVI analog input, allowing the VFD to maintain a fixed phase delay.
The manual explains system wiring, physical mounting for different VFD power ratings, and detailed installation and configuration steps, including switch settings, carrier‑frequency selection, and adjustment of the input‑output delay (0.0–20.0 ms) to achieve phase synchronization. This manual is written in Chinese.
| Carrier Frequency | >9000 Hz |
|---|---|
| Input‑Output Delay Adjustment Range | 0.0–20.0 ms |
| Control Voltage Switch Position | 0~5 V |
The delay can be set from 0.0 ms up to 20.0 ms.
