Installation and Wiring

Mount the drive vertically on a flat surface, ensuring proper clearance for airflow. Connect the mains supply to terminals R/S/T and the motor to U/V/W. Use shielded cables for control connections and keep them separated from power cables. The control terminals are clearly labeled for input and output wiring. The drive features a built‑in braking chopper; connect an external resistor to terminals B1/B2 for dynamic braking if needed. After wiring, perform the motor auto‑tuning function to optimize control parameters.

Compliance
