1. 1

   Check for sources of electromagnetic interference (EMI) or noise near the Pulsecoder cable and servo amplifier; mitigate if found.

2. 2

   Inspect the Pulsecoder cable and its connectors for any signs of damage, proper seating, and secure connections.

3. 3

   Verify that the Pulsecoder cable shield is properly grounded at the servo amplifier side.

4. 4

   If noise, cabling, and connections are confirmed to be in good condition, replace the Pulsecoder unit.
