If the voltage is correct, check the brake coil for resistance (an open circuit indicates a burned coil). If the DC voltage is significantly lower than $0.9 \\times V_{ac}$, the rectifier bridge may be damaged.\u003c\/span\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"koeed-faq-item\"\u003e\n    \u003cspan class=\"koeed-faq-q\"\u003e2. Why does the motor take several seconds to stop after power is cut?\u003c\/span\u003e\n    \u003cspan class=\"koeed-faq-a\"\u003eThis is typically caused by \"Slow Switching\" logic (switching on the AC side). To achieve rapid braking, the circuit must be switched on the DC side (between the rectifier and the brake coil), which allows the magnetic field to collapse instantly without the inductive flyback delay.\u003c\/span\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"koeed-faq-item\"\u003e\n    \u003cspan class=\"koeed-faq-q\"\u003e3.
