Applicable Industries:

• Semiconductor Manufacturing — Wafer stage positioning, pick-and-place
• Electronics Assembly — SMT feeder control, precision indexing
• Machine Tools — CNC axis drive, spindle control
• Printing & Packaging — Register control, cut-to-length
• Robotics — Joint axis servo control

Installation Requirements:

• Mount in a ventilated enclosure with minimum 100 mm clearance on all sides
• Use shielded cable for encoder signals (maximum 10 m for differential, 5 m for single-ended)
• Connect motor power cable (U, V, W) with proper phase sequence
• Connect grounding terminal to panel earth (resistance ≤ 100 Ω)
• Install EMC filter on input power line (recommended for industrial environments)
• Maximum motor cable length: 50 m (with output filter installed)

Precautions:

• Do not operate the drive with the front cover removed — high voltage present
• Do not exceed rated output current — will trigger overcurrent fault and may damage IGBT modules
• Ensure proper phase sequence on motor power connection — reverse rotation will occur with wrong sequence
• Use Yokogawa-approved servo motor — mismatched motor will cause tuning failure
• Perform auto-tuning after every mechanical change (coupling, load change, gear ratio change)
• Replace cooling fan every 30,000 hours or when noise increases
