Drive Overtemperature

What does Overtemp mean?

This fault signifies that the internal temperature of the VSD has exceeded its safe operating limits. This can result from insufficient cooling (e.g., blocked filters, fan failure), high ambient temperatures, or excessive motor load. Sustained high temperatures will degrade electronic components, potentially causing permanent damage or drive shutdown to protect itself from thermal stress.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Reduce the motor load if possible, especially during periods of high ambient temperatures.

2. 4

   Ensure the drive enclosure is not in direct sunlight or exposed to other external heat sources.
