If high inertia loads are present, the internal regeneration capability may trigger a \u003cstrong\u003eAL005 (Overvoltage)\u003c\/strong\u003e fault.

When utilizing the CN1 interface for pulse train positioning, always use twisted-pair shielded cables with the shield terminated at the drive chassis end only. Ensure that parameters P2-15 through P2-17 (Digital Input Filters) are correctly configured to match the input signal frequency to filter out signal bounce or external high-frequency EMI.\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; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e Before installing, removing, or wiring the drive, ensure that the main power source is completely disconnected.
