Working Principle:
The PMSM rotor, equipped with NdFeB magnets, is driven by a three-phase rotating stator field from the servo amplifier. The integrated Hiperface encoder, mounted on the rear shaft, reads a glass code disk attached to the rotor. The encoder outputs absolute position data (Gray code, 131,072 counts/rev) via the M23 connector to the drive. The drive executes servo control loops using this feedback for precise motion control.

Advantages:

• Fully integrated design — no separate encoder, no alignment required
• IP65 protection maintained even with encoder
• Reduced installation time — single cable connection
• Absolute position available immediately after power-on
• Lower total system cost vs. separate encoder + motor
