Communication Error2

Was bedeutet dCE2 ?

Similar to dCE1, this communication error points to a temporary drive hardware issue primarily caused by electrical noise. This can lead to unreliable drive performance, erratic operation, and potential system downtime.

• Transient voltage spikes or surges on the control power supply (e.g., 24VDC) disrupting internal logic.
• Failure of optical isolators or galvanic isolation barriers used in internal communication paths.
• Inadequate shielding of internal communication traces on the PCB, making them susceptible to crosstalk.
• Software timeout in an internal communication protocol due to excessive processing load or unexpected delays.
• Corrosion or oxidation on critical internal board-to-board connector pins, causing high resistance.

1. 1

   1. Reset the drive (e.g., by cycling the control power via terminal S1/SC or equivalent) and check status.

2. 2

   2. Check the integrity of the main earth connection from the drive to the central grounding point.

3. 3

   3. Inspect for loose internal components or boards that may be vibrating and causing intermittent connections.

4. 4

   4. Review the ambient environment for strong electromagnetic fields or radio frequency interference (RFI) sources.

5. 5

   5. Replace any suspect internal ribbon cables or small interconnection wires that appear stressed or damaged.

6. 6

   6. If the drive is equipped with a fan, verify its operation and ensure proper airflow over internal components.
