If you are operating this drive in environments with sensitive instrumentation, digital load cells, or high-speed serial communications, you must install an external line filter on the input side and use fully shielded motor cables to mitigate high-frequency electromagnetic noise. Ensure the carrier frequency parameter is adjusted appropriately to maintain low thermal load inside sealed non-ventilated enclosures.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eDuring initial commissioning, if the drive is not wired to an external emergency safety relay, the STO1 and STO2 terminals must be jumpered to the common reference (+24V \/ DCM) using the factory-provided shorting clips. Leaving these terminals open will cause the drive to display continuous safety fault states (STL1 or STL2) and block output power initialization.
