Compatibility\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eThe HG-SR702BJ is designed for seamless matching with the MR-J4-700A, MR-J4-700B, and MR-J4-700GF series servo amplifiers. When upgrading from legacy HC-SFS or HA-LFS series motors, evaluate the structural shaft dimensions and verify mounting hole compatibility, as physical frame alignments vary between older generations and the HG-SR series.\u003c\/p\u003e\n\n\u003ch4\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eDue to the motor's substantial 7.0 kW power and high-inertia load capacity, dynamic deceleration phases generate significant regenerative energy. System designers must size and integrate appropriate external regenerative brake options (such as MR-RB50 or MR-RB137) based on duty cycles to prevent overvoltage faults (AL 30 or AL 33) on the matching servo drive. Additionally, the electromagnetic brake (B suffix) must never be used for dynamic braking or active deceleration; it is strictly rated as a static holding brake.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eAlways ensure that the MS connection plugs for power, brake, and encoder are fully sealed and strain-relieved. If mounting the motor vertically with the shaft facing upward, design a drip loop in the cabling to prevent moisture or oil runoff from directly pooling on the MS connectors. Do not run the oil seal dry; ensure a light coating of gearbox lubricant is present at the shaft-seal interface to avoid premature seal failure and thermal degradation.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e Prior to any maintenance or installation activity, isolate the primary 3-phase power feeding the servo amplifier.
