Continuous operation at high speeds inside unventilated enclosures can raise the internal temperature of the motor winding beyond safe limits. Furthermore, do not use the integrated 24VDC safety brake for dynamic braking or load stopping; it is rated strictly as a holding brake. Using it to stop rotating loads will cause rapid wear on the friction plates and early system failure.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d; border-bottom: 2px solid #2b6cb0; padding-bottom: 0.25rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eWhen interfacing with MR-J2S series drives, configure an external surge-absorbing diode across the brake control relay contacts to suppress high-voltage spikes generated by the inductive brake coil.
