What Happens to the Drive State When Deceleration Ramp Adaptation (bRA) Is Enabled on Altivar Drives?

Resolution:

When a stop command is issued, the drive enters the DEC (decelerating) state. This indicates that the motor speed is being reduced according to the configured deceleration ramp.

If the Deceleration Ramp Adaptation (bRA) function is enabled (set to YES), the drive may automatically increase the deceleration time if needed. This adjustment helps prevent issues such as DC bus overvoltage and ensures a safe, controlled stop.

The drive remains in the DEC state while the motor is slowing down—even if the ramp is being adapted.
Once the motor reaches zero speed, the drive transitions to the RDY (ready) state, indicating it is stopped and ready for the next command
