5. Installation & Wiring
5.1 Environmental Requirements
- Temperature: 0°C to 40°C (32°F to 104°F)
- Humidity: Less than 90% RH, non-condensing
- Location: Avoid direct sunlight, corrosive gases, flammable materials, and excessive dust. Ensure adequate ventilation.
5.2 Wiring Connections
Proper wiring is crucial for safe and reliable operation. Refer to the wiring diagrams below for correct connections.
Figure 5.1: Single-phase and Three-phase wiring diagrams for the VFD.
5.2.1 Power Input (R, S, T / L1, L2)
- Single-Phase 220V Input: Connect the live wire to L1 and the neutral wire to L2.
- Three-Phase 380V Input: Connect the three phase wires to R, S, and T terminals.
- Always ensure a fuse is installed on the input line for protection.
5.2.2 Motor Output (U, V, W)
Connect the three motor phase wires to the U, V, and W terminals of the VFD. Ensure correct phase sequence for desired motor rotation. If the motor rotates in the wrong direction, swap any two of the U, V, W connections.
5.2.3 Braking Resistance (P+, PB)
If dynamic braking is required, connect an external braking resistor between the P+ and PB terminals. Refer to the VFD specifications for appropriate braking resistor values.
5.2.4 Grounding (PE)
Connect the PE (Protective Earth) terminal to a reliable ground point. Proper grounding is essential for safety and to minimize electromagnetic interference.
5.2.5 Control Terminals
The VFD features various control terminals for external control signals, including digital inputs (DI), analog inputs (AI), analog outputs (AO), and communication ports (RS485). Refer to the detailed diagram for specific terminal functions.

6. Setup & Configuration
The VFD's control panel allows for parameter setting and monitoring. The display shows operational status and parameter values, while buttons like PRG, M-FUN, SHIFT, RUN, STOP/REST, UP, DOWN, and ENTER are used for navigation and input.
6.1 Basic Parameter Settings
Upon initial power-up, it is essential to configure basic motor parameters and operating modes. Common parameters include:
- Motor Rated Power: Set according to your motor's nameplate.
- Motor Rated Voltage: Set according to your motor's nameplate.
- Motor Rated Current: Set according to your motor's nameplate.
- Maximum Output Frequency: Typically 50Hz or 60Hz, but can be set up to 320Hz.
- Acceleration/Deceleration Time: Adjust these parameters to control how quickly the motor speeds up or slows down.
- Control Mode: Select between V/F control (Volts per Hertz) or Vector control based on application requirements. Vector control offers better performance for demanding applications.
Refer to the detailed parameter list in the full product manual (if available) for advanced settings, including PID control, simple PLC functions, and communication settings.
