Key Features:

• 32-bit single-turn resolution — 4.29 billion positions per revolution, highest resolution in S-Series
• EnDat 2.2 interface — Industry-standard protocol, compatible with Heidenhain, Kollmorgen AKD, and other EnDat-capable drives
• Hollow shaft design — Enables direct motor shaft mounting (no coupling required)
• Ultra-high accuracy — ±3 arcseconds, ideal for precision metrology and semiconductor applications
• High update rate (2048 Hz) — Enables smooth motion at high speeds
• IP67 sealed construction — Full environmental protection

Applicable Industries: Semiconductor wafer steppers, precision CNC spindles, coordinate measuring machines (CMM), optical alignment systems, medical imaging equipment, aerospace test rigs, precision robotics

Installation Requirements:

• Mount using M58 × 1 rear flange thread
• For hollow shaft mounting: insert motor shaft with H7 tolerance fit, secure with clamp screw at 3 Nm
• Use shielded cable for EnDat connection — Maximum cable length 10 m (without repeater)
• Ensure 5 VDC supply is regulated to ±5% tolerance

Precautions:

• Do not exceed 12,000 RPM mechanical speed
• Do not apply radial loads exceeding 20 N
• EnDat 2.2 requires stable 5V power — Use regulated supply, not drive-side 5V
