Installation & Maintenance
Ensure the shaft of the encoder matches the application’s coupling diameter (6mm solid shaft).
Align the encoder shaft precisely with the machine shaft; use flexible couplings to avoid misalignment stress.
Securely mount the encoder with the provided hardware to minimize vibration.
Connect power supply within the recommended voltage range (5-24V DC) following the wiring diagram.
Use shielded cables for signal wiring to prevent electromagnetic interference.
Perform regular cleaning to remove dust and debris; avoid using harsh chemicals or water jets.
Check wiring and connectors periodically for secure connections and signal integrity.
Replace the encoder if signs of mechanical wear or unstable signals arise.
