Frequently Asked Questions (FAQ)

• Q1: What is the difference between HG-KR053 and HG-KR13B?
  • A: HG-KR053 is 50W, HG-KR13B is 100W. Choose 053 for very small loads, 13B for higher torque needs.
• Q2: Can I use this motor outdoors?
  • A: No, indoor use only. IP65 protects from water jets but not direct sun or extreme cold.
• Q3 (Experience-based): My motor vibrates at low speed. What should I check?
  • A: Tune gain settings in your servo amplifier. Reduce load inertia or add a low-pass filter. Check coupling alignment.
• Q4 (Buying guide): What warranty and shipping do you provide?
  • A: 12-month warranty. Ship within 12-24 hours via FedEx, UPS, or DHL. Global tracking included.
• Q5: How do I set the encoder to absolute mode?
  • A: Connect a battery to the servo amplifier. Set parameter PA03 to 0001. The motor saves position without home sensor.
