This component is specifically designed as a static holding brake; active deceleration using the brake will cause thermal fatigue and mechanical failure. Ensure that deceleration is handled regeneratively via the paired MR-J4-350A\/B servo amplifier before engaging the brake.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eTo prevent encoder communication faults, utilize only genuine, double-shielded Mitsubishi feedback cables.
