Overbraking

Hva betyr F009 ?

This fault occurs in the ATV310 drive due to excessive regenerative energy returned from the motor to the drive, causing the DC bus voltage to rise above its permissible limit. This is typically triggered by sudden deceleration or a high inertia load application.

• Sudden braking command or rapid deceleration of the motor
• Load inertia is too high for the drive's inherent braking capability
• Main supply voltage exceeding 20% over the maximum acceptable level during run status

1. 1

   Increase the deceleration time parameter in the drive configuration.

2. 2

   Install a braking resistor and associated module unit if the application requires frequent or rapid braking of high inertia loads.

3. 3

   Check the main supply voltage to the drive to ensure it remains within 20% of the maximum acceptable voltage during operation.
