5.2 Wiring Diagrams
Refer to the following diagrams for correct power and motor connections. Always use appropriate wire gauges and ensure secure connections.
Figure 5.2.1: Wiring diagrams. This image presents two main wiring configurations: one for a single-phase power supply and another for a three-phase power supply. Both diagrams show connections for input (L1, L2 or R, S, T), output to motor (U, V, W), braking resistance (PB, P+), and control terminals (S5/Y, AO, AI, 485). For this specific 380V 3PH-3PH model, the three-phase power supply diagram is applicable for the main power input.
Input Power (R/L1, S, T/L2): Connect the three-phase 380V AC power supply to these terminals. For this model, use the R, S, T terminals as indicated in the three-phase power supply diagram.
Motor Output (U, V, W): Connect the three-phase motor to these terminals. Ensure correct phase sequence for desired motor rotation.
Braking Resistor (P+, PB): If a braking resistor is required for applications involving rapid deceleration or high inertia loads, connect it between P+ and PB terminals.
Ground (PE): Connect the VFD chassis to a reliable earth ground.
Control Terminals: The diagram also shows terminals for external control signals (e.g., analog input/output, digital input, RS485 communication). Refer to the detailed product manual for specific functions and programming of these terminals.
