When migrating from the HC-SFS series, note that parameters on the corresponding MR-J4 amplifier must be correctly selected using the MR Configurator2 software to ensure optimal loop tuning and prevent encoder communication faults.\n\u003c\/p\u003e\n\u003ch4\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\n  While the J-suffix indicates a robust factory-installed oil seal, the seal is not designed for submerged operation. In applications where the motor is mounted vertically shaft-up or shaft-down, implement physical drip loops and protective splash shields to prevent continuous pooling of lubricants or coolants against the shaft face, which can degrade the seal material over time.\n\u003c\/p\u003e\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\n  To minimize electromagnetic interference (EMI) issues, run the power and encoder cabling through separate grounded metallic conduits. Ensure that the motor frame is grounded directly back to the common drive plate with a minimum 10 AWG protective grounding conductor. Always verify correct polarity on the thermal sensor circuit, if configured within the drive's parameter settings.\n\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;\"\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0; font-weight: bold;\"\u003eCRITICAL WARNING: HIGH VOLTAGE AND THERMAL HAZARD\u003c\/p\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0.5rem 0 0 0;\"\u003e\n    Before performing any wiring, mounting, or maintenance on this motor, ensure that the power supply to the associated servo amplifier has been disconnected for at least 15 minutes.
