VI. Installation and Debugging Key Points

Vertically installed in the strong current risk control cabinet, the fan air duct is vertically unobstructed, with a ≥150mm heat dissipation gap reserved at the top and bottom.

Power lines (3×AC + N), encoder lines, and signal lines are strictly separated and shielded for wiring, with 360° reliable grounding.

Select **≥6mm²** power cables, twisted shielded encoder lines to ensure stable transmission of high current.

Before debugging, confirm that the voltage, motor parameters, and feedback type match, and complete parameter self-tuning through DriveGui software.

Wait for 10 minutes after power off, and wait until the bus voltage drops to <60V before operating, to prevent high-voltage electric shock.

Regularly clean the fan and heat dissipation grille, check the tightness of the large current terminals, and prevent poor contact and overheating.
