External temperature 1

What does 4981 mean?

An external temperature sensor (sensor 1) has detected that the monitored equipment (e.g., motor winding) has exceeded its programmed temperature limit. This fault protects external components from overheating and potential damage, which could lead to critical system failure.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Review the temperature limits set in the drive's parameters for sensor 1.

2. 4

   Check for any external conditions causing the overheating, such as mechanical overload or inadequate cooling.
