When activated (e.g., via a safety relay or door switch), it electronically disables power to the motor, making it safe for personnel to approach. It can eliminate the need for a separate mechanical contactor, simplifying safe system design.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eWhat are the benefits of a 22-bit absolute encoder?\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eA 22-bit encoder provides \u003cstrong\u003eextremely high resolution (over 4 million positions per revolution)\u003c\/strong\u003e and absolute position data. This means the system knows its exact position immediately on power-up without needing a homing routine, enabling faster start-up and higher precision.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eCan I use this amplifier with an incremental encoder motor?\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe \u003cstrong\u003eMR-J3-11KB-LR\u003c\/strong\u003e is designed for use with \u003cstrong\u003eabsolute encoder motors\u003c\/strong\u003e. Using it with an incremental encoder motor would not utilize its full capabilities and may require different parameter settings or may not be supported. Always match the amplifier to the motor's feedback type.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eHow does the STO function get wired and activated?\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe STO function is typically activated through two redundant \u003cstrong\u003e24VDC safety input terminals\u003c\/strong\u003e on the amplifier. These are connected to a safety device (like a relay, light curtain, or door switch) that meets safety category requirements (e.g., Cat. 3, PLd).\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eIs the built-in regenerative braking sufficient for high-cycle applications?\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe internal regenerative resistor is suitable for many standard applications. For \u003cstrong\u003ehigh-duty cycles, high inertia loads, or frequent rapid stops\u003c\/strong\u003e, the internal resistor may overheat. In such cases, an external regenerative resistor or regenerative converter option should be used.\u003c\/p\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
