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.
Additional Steps
Steps 1–2 are listed in Priority Fix.
- 3
Correct the axis type to match the physical hardware and intended control method.
- 4
Save configuration changes and restart the NC system.
