When replacing older HC-SFS or HC-RFS series motors, confirm the mounting flange PCD and encoder feedback parameters in the parameters of your MR Configurator software, as gain settings will require adjustment to prevent mechanical resonance.\u003c\/p\u003e\n\n\u003ch4\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eAlways ensure that your configuration accounts for thermal radiation. The continuous torque capability of the HF-SP121B is rated based on installation on a heat-dissipating aluminum flange. Operating the motor continuously at high duty cycles in ambient temperatures exceeding 40 degC without adequate ventilation will degrade winding insulation and trigger amplifier overtemperature faults.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eThe built-in electromagnetic brake is dedicated strictly for holding and must not be used for deceleration.
