4301

Axis type not allowed

Beckhoff · TwinCAT 2 NC

What does 4301 mean?

The value configured for the axis type is unacceptable because it is not defined within the system's supported types. Valid types include 1: Servo, 2: High/low speed, and 3: Stepper motor. An incorrect axis type means the NC cannot apply the correct control algorithms and parameters, leading to axis malfunction.

Complete Troubleshooting Guide

  1. 1

    Check the axis type parameter in the NC configuration for the affected axis.

  2. 2

    Ensure the value corresponds to one of the defined types: 1 (Servo), 2 (High/low speed), or 3 (Stepper motor).

  3. 3

    Correct the axis type to match the physical hardware and intended control method.

  4. 4

    Save configuration changes and restart the NC system.
