Motor protection

What does F84 mean?

A stop with inhibit indicating that motor utilization is too high, often detected by IN-UL monitoring (P345/P346). This protects the motor from sustained overload conditions.

• Motor utilization too high
• IN-UL monitoring (P345/P346) tripped due to excessive load

Click steps to track your progress.

1. 1

   Check parameter P345 / P346 (IN-UL monitoring) settings for appropriate trip levels

2. 2

   Reduce the mechanical load on the motor

3. 3

   Extend acceleration/deceleration ramps to reduce peak current demands

4. 4

   Implement longer rest periods between operations to allow motor cooling
