Replacing an Angle Encoder

Before You Begin

Safety: Stop the machine, follow the site lockout/tagout procedure, verify that hazardous energy is controlled, and release or secure stored mechanical and pneumatic energy before opening a panel, removing a guard, or adjusting components. Electrical work must be performed by a qualified technician.

Step 1: Remove the blue metal shroud that protects the angle encoder. There are (4) 9/16″ bolts that you will need to remove.

Step 2: Inspect the encoder for anything that could cause the encoder to malfunction.

• One or both of the metal tabs/clips that hold the encoder in place could be broken.
• The set screw could be loose allowing the shaft to spring freely from the encoder.

Step 3: Remove the (2) screws on the spring clip that attach the encoder to the motor

Step 4: Remove the set screw for the encoder.

Step 5: Slide the encoder off the shaft, and replace it with a new encoder.

Repeat steps 1-4 in reverse order.

Confirm the Result

After restoring the machine through the approved startup procedure, confirm that the position or count changes in the correct direction, returns consistently, and reaches the commanded value without an encoder, calibration, or overrun warning.

If the issue remains, record the exact on-screen message, affected component, indicator-light state, and the last change made. Provide those details to Enventek Technical Support; do not repeatedly recalibrate or replace parts without identifying the cause.
