Overtemperature

What does 4630 mean?

Overtemperature has been detected or reported within the drive or terminal. This indicates that the operating temperature of the drive, motor, or associated I/O terminal has exceeded its safe limits. Prolonged overtemperature operation can cause permanent damage to electronic components, insulation, and lead to premature failure of the equipment.

Complete Troubleshooting Guide

1. 1

   Check cooling fans and heatsinks on the drive/terminal for blockages, dust accumulation, or failure.

2. 2

   Verify that the ambient operating temperature of the control cabinet is within the manufacturer's specified range.

3. 3

   Inspect for excessive motor or drive loading that could be generating abnormal heat.

4. 4

   Ensure proper ventilation around the drive and terminal units.
