Common Installation Issues & Solutions

Q1: How to identify drive voltage rating for different power grids?

Check the drive nameplate: SGD7S-xxxA models are 200V-class, SGD7S-xxxD are 400V-class. For 480V North American grids, use dedicated high-voltage models. Adjust parameter Pn003 for 50/60Hz grid compatibility.

Q2: Resolving encoder error A.510 after wiring?

Use original shielded twisted-pair encoder cable and ground shield at drive end only. Keep encoder cables 20cm from power cables. Check for bent connector pins from shipping.

Q3: Proper grounding practices for signal stability?

Requires ground resistance ≤4Ω with single-point grounding. Use ground wire cross-section ≥2.5mm², length under 1 meter. Test resistance before powering on.

Q4: Parameter import errors after drive replacement?

Import only core parameters: motor model, control mode, electronic gear ratio, and limit parameters. Reset others to factory defaults and run motor auto-recognition.
