It requires two power connections: a 3-phase 200-230V AC for the main circuit and a separate 1-phase 200-230V AC for the control circuit. Ensure the cooling fan has clear airflow. The environment must be clean, dry, and within 0°C to 55°C. Use the RS-422 port for control signals. Due to its open (IP00) structure, protect it from dust, debris, and liquids.\u003c\/p\u003e\n\u003ch3\u003eExpert FAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat type of machinery is this amplifier suited for?\u003c\/strong\u003e\u003cbr\u003eIt is ideal for large industrial machines like metal forming presses, heavy-duty conveyors, large CNC mills, or injection molding machines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy are there two separate power supply inputs?\u003c\/strong\u003e\u003cbr\u003eSeparating the high-power main circuit from the sensitive control circuit improves stability and protects the control electronics from electrical noise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does \"force-cooled\" mean?\u003c\/strong\u003e\u003cbr\u003eIt uses an internal fan to actively blow air over the components.
