❓ Frequently Asked Questions

• Q1: Can I run this motor without a Mitsubishi driver?
  A: No. It requires MR-J4 or MR-JE series servo amplifiers to operate the 22-bit absolute encoder.
• Q2: Does the IP65 rating mean I can use it outdoors?
  A: It resists rain splashes but not direct high-pressure washdown. Indoor industrial use recommended.
• Q3: What is the effective resolution for linear motion?
  A: With a 5mm pitch ball screw, one encoder count moves 0.0012 µm – ultra fine positioning.
• Q4: Where can I find 3300 5mm Proximity Probes?
  A: They measure vibration in turbines; not related to motor control, but often used in same plant monitoring systems.
• Q5 (Experience-based): My motor vibrates at low speed – what to do?
  A: Increase the “speed feedback filter” setting in MR Configurator2 from 0.5ms to 2ms. Reduces high-frequency resonance.
• Q6 (Experience-based): Can I connect two motors to one power supply?
  A: Yes, use a shared DC bus on MR-J4-TM series triple-axis drives. Each motor draws max 3.1A peak.
• 📘 Purchasing Guidance:
  • └─ Check load inertia: If inertia ratio >15x, use external regenerative resistor.
  • └─ Need holding brake? HG-MR053 has no built-in brake. Order external brake kit (Mitsubishi MR-BK1).
  • └─ Cable length: For runs >20m, add ferrite cores to encoder cables.
  • └─ Spare recommendation: Keep one MR-J4-10A drive and one encoder cable per 5 motors.
