Technical Specifications:
  • Model: CR06660-JW — 6,600 lines per revolution (26,400 counts × 4 quadrature)
  • Commutation: 3-channel U/V/W Hall-equivalent signals at correct electrical offset
  • Output Type: Differential line driver (RS-422 compatible), TTL/HTL option
  • Supply Voltage: 5 V DC ± 5 %
  • Index (Z) Channel: One pulse per revolution
  • Accuracy: ± 30 arc-seconds typical
  • Max Shaft Speed: 6,000–8,000 rpm
  • Connector: JW suffix = specific pinout / cable assembly (often 12-pin circular)
  • Operating Temp: -20 °C to +85 °C
  • Ingress Protection: IP50 (on motor); IP65 with shaft seal
    Function:​ Provides position feedback + electronic commutation signals to AKD/S300/S400 drives; enables sensorless-to-sensored startup transition.
    Notes:​ Do not interchange with SFD or EnDat — this is legacy incremental + commutation only.
