5 Professional FAQs with Buying Advice

• Q1: Can this replace an A06B‑6140‑H045?
  A: Yes, but check the current rating. This H055 provides 228 A vs 200 A – better for heavy cuts. Verify motor compatibility.
• Q2: Do I need a separate regenerative unit?
  A: For high‑deceleration loads, yes. We recommend A06B‑6087‑HXXX series. Our engineers can size it for your application.
• Q3: What cable set is required?
  A: Use FANUC power cable A06B‑6093‑K… and feedback cable A06B‑6064‑K…. We stock both – ask for a bundle deal.
• Q4: Can it run in single‑phase?
  A: No – strictly 3‑phase. Running on single‑phase will trigger undervoltage alarm.
• Q5: How to choose between this and A06B‑6140‑H045?
  A: Choose H055 for spindle or dual‑axis heavy milling. For lighter duty, H045 is more cost‑effective. Share your motor model – we guide you.
