Diagnose Unknown Blade Motor Noises

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.

If you are experiencing constant or persistent noises coming from one of your blade motors the cause is typically one of three things.

• Reason Number 1: The (normally blue) shroud that covers the encoder is vibrating and you are hearing the noise of metal on metal as it vibrates.
  • Solutions: Using a tap, tap a hole for a small screw to keep the metal from vibrating, or use a piece of folded paper, double sided tape, or similar item to put in between the metals so they can’t vibrate against each other.

• Reason Number 2: One or more parts of the blade brake assembly have become loose and are vibrating.
  • Solution: Remove the saw blade and manually turn on (ONLY) the motor that is causing the issue and carefully using your hand touch the blade brake assembly to see if it is vibrating. If it is vibrating determine what has become loose, turn off the motor, engage the e-stop and tighten it back up.

• Reason Number 3: If you have ruled out reason number 1 and 2 the last option is that the motor has gone bad and needs to be replaced. If this is the case please contact Enventek support 269 815 4150 and we will assist you in purchasing a replacement motor.

Confirm the Result

After checking all connections and reinstalling covers, restore power through the approved startup procedure. Confirm that the correct device comes online without a disconnected-drive or communication warning, then test its command, direction, and stopping response in a controlled mode.

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.
