Installation Steps & Maintenance
-
Align the encoder’s 6 mm shaft carefully with the machinery shaft to avoid misalignment and undue stress.
-
Securely mount the encoder using the designated mounting holes or flange to prevent vibration during operation.
-
Connect encoder output wires according to wiring diagram for ABZ phase signals, matching the control system requirements.
-
Confirm power supply is within specified voltage range (5-24V DC).
-
Perform testing by rotating the shaft to verify pulse output and direction detection.
-
For routine maintenance, periodically inspect the encoder for dirt, dust, and secure wiring connections. Clean gently without solvents if necessary.
-
Due to sealed bearings, lubrication is generally unnecessary, minimizing upkeep.
