🧩 Model Interpretation (C205)

• C205 = Specific variant/version code
• Defines:
  • Current rating / capacity
  • Hardware revision
  • Compatibility with certain CNC controls

👉 Same base family as:

• H205, H209, C202, etc.
  But ratings and internal configuration differ, so exact match is recommended.

⚠️ Important Notes

• This is NOT a motor → it is a drive/amplifier
• Always match:
  • Full part number (A06B-6124-C205)
  • Or confirm compatibility before replacement
