If your installation environment exposes the motor to splashing oils, heavy cutting fluids, or high humidity, the \u003cstrong\u003eHG-KR73J\u003c\/strong\u003e variant featuring an integrated shaft oil seal must be utilized instead. Additionally, do not mistake the HG-KR series for the ultra-low inertia \u003cstrong\u003eHG-MR73\u003c\/strong\u003e series; though physically identical in spatial dimensions, they feature completely distinct rotor inertia envelopes and require dedicated tuning profiles within the MR Configurator2 programming suite.\n\u003c\/p\u003e\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.25rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\n  Ensure the external load-to-motor inertia ratio does not exceed the recommended maximum of \u003cstrong\u003e17 times\u003c\/strong\u003e the motor's rotor inertia. Exceeding this boundary without severe gain reduction will trigger servo loop oscillation, audible high-frequency vibration, and eventual overcurrent faults (such as AL.50 or AL.51) during rapid acceleration phases. In tightly sealed control cabinets, verify that ambient motor temperature does not push past the 40 degC threshold, as continuous heavy operation near 2.4 N m rated torque can drive the internal windings close to their Class B thermal limits.\n\u003c\/p\u003e\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.25rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\n  To prevent feedback communication dropouts, always employ dedicated, double-shielded encoder cables (such as Mitsubishi’s MR-EKCBL_M-H or MR-EKCBL_M-L cables). The 22-bit high-resolution serial feedback signal is sensitive to high-frequency electromagnetic noise; therefore, routing motor power cables and feedback lines in separate, grounded metal conduits is highly recommended. Ensure the motor frame is securely grounded back to the companion MR-J4 amplifier's earth terminal to minimize potential leakage currents.\n\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d; margin-top: 1.5rem; margin-bottom: 0.5rem;\"\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c;\"\u003eCRITICAL WARNING:\u003c\/strong\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0.5rem 0 0 0;\"\u003e\n    Verify that primary AC input power supplying the companion MR-J4 servo amplifier is completely disconnected and locked out.
