4306

Slow manual velocity not allowed

Beckhoff · TwinCAT 2 NC

What does 4306 mean?

The value configured for the slow manual velocity parameter is not allowed. The accepted range for this parameter is [0.0, 10000.0] (e.g., m/min). An invalid setting prevents the system from reliably executing slow manual movements, potentially leading to no motion or jerky manual control.

Complete Troubleshooting Guide

  1. 1

    Verify the slow manual velocity parameter in the NC configuration for the affected axis.

  2. 2

    Ensure the value is within the allowed range of 0.0 to 10000.0 (and is positive if movement is desired).

  3. 3

    Adjust the parameter to a suitable value for safe and controlled manual operation.

  4. 4

    Save configuration changes and restart the NC system.
