Low Temperature (Adv. Code 0)
Vacon · X4 AC Drive
What does 21 mean?
This fault is triggered when the heatsink temperature drops below -10.0 degrees Celsius. Operating the drive outside its specified low-temperature limits can affect the performance and reliability of internal components, particularly electrolytic capacitors and LCD displays. This prevents safe operation and could cause damage.
Complete Troubleshooting Guide
- 1
Verify that the ambient temperature in the drive's operating environment is maintained within the manufacturer's specified range (typically above 0°C).
- 2
If the temperature is too low, take measures to increase the ambient temperature around the drive, such as using enclosure heaters or relocating the drive to a warmer environment.
- 3
Ensure that the drive is not exposed to drafts or unusually cold air currents.
- 4
Allow the drive to warm up to an acceptable operating temperature before attempting to restart.
