Oiltech Controls’s Insight

• This 3-axis amplifier reduces panel space by 30% versus single-axis units.
• Wide output frequency range (0.1–800 Hz) supports high-speed spindle and positioning.
• Rated 3 A per axis – verify motor current before selection.
• Built-in overcurrent and thermal protection – no external relays needed.
• Common failure: DC bus fuse – replace with same rating.

Maintenance & Diagnostics

• Front LED code table – refer to manual for fault decoding.
• Monitor output current via analog test points.
• Fan cleaning every 6 months in dusty environments.
• Fault memory stores last 3 events.

5 Professional FAQs

• Q1: Can I use this for a 2-axis application?
  Yes, you can leave one axis unused. No software change required.
• Q2: What is the max cable length to motor?
  Keep motor cables under 20 meters for stable performance.
• Q3: Does it support absolute encoders?
  Yes, with FANUC serial encoder interface (αi/βi).
• Q4: How to choose between this and A06B-6117-H303#A?
  The H303 is base model; #A has enhanced EMI filter. Choose #A for noisy environments.
• Q5: What if output current exceeds 3 A?
  The amp will trip on overcurrent. Check motor load or reduce acceleration.
