Maximum braking time exceeded

Was bedeutet F6024 ?

The drive has exceeded the maximum allowable braking time during a deceleration sequence. This means the motor or load took too long to come to a stop or reduce its speed, often indicating an issue with the braking system or excessive inertia.

• Insufficient braking torque or worn mechanical brakes.
• Excessive inertia of the load relative to the drive's braking capacity.
• Incorrectly configured deceleration ramp or braking parameters (e.g., S-0-0078 Ramp Time Neg).
• Faulty braking resistor or chopper circuit.
• External forces or continuous regenerative load.

1. 1

   Check the mechanical brakes (if present) for proper function and wear, ensuring they provide adequate braking torque.

2. 2

   Verify the drive's deceleration ramp parameters (e.g., S-0-0078 Ramp Time Neg) are set appropriately for the application's inertia.

3. 3

   Ensure the braking resistor is correctly sized and connected, and its chopper circuit within the drive is functioning.

4. 4

   Inspect the mechanical system for any binding or high friction that would prolong deceleration.

5. 5

   If applicable, verify that there are no external forces or continuous regenerative loads hindering deceleration.
