Installation & Wiring Notes
- Mount the motor on a rigid base to minimize vibration; use matching mounting brackets and torque-tighten fasteners as per specifications
- Match with PRONET-E-02A drive; connect power terminals and encoder cable (CN2 interface of the drive) correctly
- Use shielded twisted-pair cables for the encoder to reduce electromagnetic interference; ground the cable shield at the drive end
- Ensure the oil-sealed shaft (code "22") is properly aligned with the load to avoid excessive radial force on the bearing
- Wait at least 5 minutes after power-off before performing wiring checks to prevent electric shock
