For advanced, high-speed multi-axis systems, connect it via the \u003cstrong\u003eSSCNET III\u003c\/strong\u003e fiber optic network to a compatible Mitsubishi motion controller or PLC.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eIs it safe to use in a dirty workshop?\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eNo. The amplifier has an \u003cstrong\u003eIP00\u003c\/strong\u003e open structure. It must be installed inside a sealed electrical enclosure (control panel) to protect it from dust, chips, and liquids, while ensuring adequate cooling airflow.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eWhat is a key parameter to set correctly during setup?\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eAccurately setting the \u003cstrong\u003eload inertia ratio\u003c\/strong\u003e is critical. An incorrect value can lead to poor tuning, mechanical vibration, or unstable operation. Always calculate or measure your system's inertia for optimal performance.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eThe amplifier shows an overload alarm. What are the first steps?\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eFirst, check if the connected mechanical load is jammed or too heavy. Then, verify the amplifier's installation environment temperature is within the 0-55°C range. Also, ensure the cooling fan is working and the heatsinks are not blocked by dust.\u003c\/p\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
