Speed monitoring

What does 08 mean?

The drive's speed monitoring function has been triggered, indicating that the drive is operating under an excessive load. This causes the drive to deviate significantly from its commanded speed or exceed a predefined slip limit. This monitoring is typically active when DIP switch S4/2 (for AS-interface versions) or S2/4 (for standard versions) is 'ON', or if additional function 13 is active. Persistent overloading can lead to motor and inverter damage.

• Drive is overloaded, causing speed deviation from the setpoint.
• DIP switch S4/2 (AS-interface version) or S2/4 (Standard version) is set to 'ON', enabling speed monitoring, and a speed deviation occurred.
• Additional function 13 is active, enabling speed monitoring, and a speed deviation occurred.

Click steps to track your progress.

1. 1

   Reduce the mechanical load on the drive system.

2. 2

   Verify the setting of DIP switch S4/2 (AS-interface version) or S2/4 (Standard version) if speed monitoring is not desired for the application.

3. 3

   Check if additional function 13 is active and review its associated parameters.

4. 4

   Reset the fault by switching off the DC 24 V supply voltage to the inverter for at least 10 seconds.
