How to Resolve Error Code E4302 on a CNC Machine

If you are having problems with your CNC machine, you have probably encountered error code e4302. This error message is displayed when the configuration file does not match the model and version of the machine. In most cases, you can solve the issue with the help of a third-party tool. However, if you are unsure whether this tool is compatible with your CNC machine, you can check out our free online manual or contact your local support center.

The parameter entered for the CNC machine was not within the permissible range. It is necessary that the parameter is within the allowed value range or else it will fail to perform its functions. If the parameter was entered twice, the program will return an error. Additionally, the error message indicates that the parameter AT_gain and/or AT_J has been modified during the Autotuning. Further, the error memory contains additional information. The parameters _PAR_ScalingError will provide you with the location of the error.

In order to resolve this error, you must check the parameters of the drive and the encoders. Make sure they are properly wired, the encoder cable is shielded, and the encoder input is configured correctly. Also, make sure that the ambient temperature is not too high or too low. If the machine cannot be operated at this temperature, the parameter setting must be adjusted. If the problem persists, contact your Schneider Electric service representative.
