4465

Position initialization error at system start

Beckhoff · TwinCAT 2 NC

What does 4465 mean?

During the initial system start-up, the set position could not be successfully initialized for all trials (with/without overflow/underflow) within the final position minimum and maximum limits. This means the axis could not establish a valid initial position, preventing it from becoming referenced and ready for motion.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Check for mechanical obstructions or binding that could prevent the axis from reaching a valid initial position.

  2. 4

    Ensure the encoder is functioning correctly and providing valid feedback during initialization.
