❓ Frequently Asked Questions

• Q1: Can I run HG-SR502J on single-phase 200V?
  A: No. It needs three-phase 200V AC. Use a phase converter if only single-phase is available.
• Q2: The motor runs hot at max torque. Is that safe?
  A: Yes, up to 40°C ambient. For continuous peak torque, add external forced cooling fan.
• Q3 (experience): My load has high inertia. What should I set?
  A: Use MR Configurator2 “auto-tuning” with inertia ratio >10. Add regenerative resistor if deceleration heats the drive.
• Q4 (purchasing guide): Warranty and shipping details?
  A: 12 months warranty. Ships 12-24 hours after order. Carriers: FedEx, UPS, DHL. Tracking provided.
• Q5 (buying tip): Do I need a brake with this motor?
  A: HG-SR502J has no built-in brake. For vertical axis or holding torque, order HG-SR502J-BK (brake version).

🛒 Buying Guide & Support

• ▪ Check inertia: For high acceleration, add external regenerative resistor (MR-RB32).
• ▪ Cable length: Keep encoder cable under 30m. Use ferrite cores for longer runs.
• ▪ Spare recommendation: Keep one MR-J4-70A drive per 4 motors.
