Selection is based on the motor's inertia, the deceleration profile, and the duty cycle. You must use Mitsubishi's official sizing tools or consult directly with their engineering support to choose the correct resistor unit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCan this drive be used in a multi-axis system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYes. The SSCNET III\/H network allows multiple drives, including several \u003cstrong\u003eMR-J3-DU45KBS4\u003c\/strong\u003e units, to be connected to a single motion controller for synchronized multi-axis control of large machinery.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIs the cooling fan noise significant?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYes, the cooling fans for a drive of this power are substantial and generate significant airflow noise. This must be considered when planning the location of the control cabinet, often necessitating a separate electrical room or acoustic treatment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
