Drive initialization

Beckhoff · TwinCAT 2 NC

What does 4640 mean?

The drive has not been fully initialized after being created in the system. This indicates that subsequent critical steps, such as I/O initialization, drive parameterization, and a system reset, have not been performed. Without complete initialization, the drive cannot enter an operational state and will not respond to motion commands.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Manually initiate a drive reset command to complete the initialization process.

  2. 4

    Verify that all necessary drive configuration files are present and accessible.
