This document is the user manual for FRENIC-VP frequency inverter, which mainly introduces the use methods and features of frequency inverter.
This manual introduces the FRENIC‑VP series inverter, a dedicated variable‑frequency drive for fan and pump loads with quadratic torque reduction. It explains the new energy‑saving control mode, PID functions, low‑water‑stop, overload‑avoidance, and external cooling options, as well as detailed installation and wiring procedures.
Safety and usage notes cover motor insulation, temperature limits, vibration, and proper wiring, while the appendix lists model numbers, specifications, and optional accessories such as RS‑485 communication modules and multi‑function panels. This manual is written in Chinese.
| Inverter model example | FRN22F1S-4 (FRENIC‑VP) |
|---|---|
| Motor power (example) | 22 kW |
| DC reactor model (example) | DCR4-22A |
| Operating frequency range | 50 Hz → 35 Hz |
| Maximum output current | 10 A (example for 0.75 kW unit) |
It stops the pump when the water flow falls below a preset minimum, preventing unnecessary operation and saving energy.
Confirm motor insulation with the motor manufacturer, use output filters if needed, and avoid operating beyond the recommended temperature range.
