Motor Stalled

What does F6 mean?

This fault occurs when the drive is unable to accelerate the motor to its commanded speed within the programmed acceleration time. It typically signifies that the motor is experiencing an excessive mechanical load, or the acceleration time is set too aggressively for the current load. The drive attempts to provide enough current but hits its current limit (A441 [Current Limit]) before the motor reaches the desired speed. Repeated stalling can lead to motor and drive overheating and wear.

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify that parameter A441 [Current Limit] is set appropriately for the motor and application, ensuring it's not set too low.
