VII. Installation and Commissioning Tips

Install vertically in a strong power risk control cabinet. The 225 customized 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， signal lines are strictly separated and shielded wiring. 360° reliable grounding.

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

Before commissioning， confirm that the voltage， motor parameters， and feedback type match. Complete 225 customized parameter self-tuning through DriveGui software.

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

Regularly clean the 225 customized fan and heat dissipation grille， check the tightness of the high-current terminals to prevent poor contact and overheating.
