Robotic stacker encoder signal noise troubleshooting

Robotic stacker experiencing severe encoder signal interference and faults. Initial attempts to secure cable shielding have not resolved the signal noise, requiring thorough EMC and feedback circuit diagnostics. - Troubleshoot encoder feedback lines and identify root cause of signal corruption visible on oscilloscope waveforms - Inspect cable screening, earthing terminations, and shield grounding bars across feedback wiring - Validate signal integrity at the drive/controller under operational running conditions - Rectify wiring or screening issues causing high-frequency noise injection - Work scheduled between 07 December 26 and 11 December 26 with an estimated duration of 16 hours
