Overview of NC errors TwinCAT 48 Version: 1.1 Error(Hex) Error(dec) Error type Description 4B37 19255 Parameter "Number of columns invalid" The number of columns of a cam table is invalid. • The number of columns of a motion function is not equal 1 • The number of columns of a standard cam table is not equal 2 • The number of columns does not match another parameter (ValueSelectMask) 4B38 19256 Parameter "Step size invalid". The increment for the interpolation is invalid, e.g. less than or equal to zero. Error numbers 0x4B0F, 0x4B40 to 0x4B4F are used in the TcNc-Lib: 4B40 19264 Monitoring "Terminal type not supported" The terminal used is not supported by this function block.
4B41 19265 Monitoring "Register read/write error" This error implies a validity error. 4B42 19266 Monitoring "Axis is enabled" The axis is enabled but should not be enabled for this process. 4B43 19267 Parameter "Incorrect size of the compensation table" The specified table size (in bytes) does not match the actual size 4B44 19268 Parameter The minimum/maximum position in the compensation table does not match the position in the table description (ST CompensationDesc) _ 4B45 19269 Parameter "Not implemented" The requested function is not implemented in this combination Error numbers 0x4B50 to 0x4B5F are used in the TcRemoteSyn-Lib:
Error numbers 0x4B60 to 0x4B6F are used in the TcMc2-Lib in the buffered commands context: 4B60 19296 Monitoring "Motion command did not become active" A motion command has been started and has been buffered and confirmed by the NC. Nevertheless, the motion command did not become active (possibly due to a terminating condition or an internal NC error). 4B61 19297 Monitoring "Motion command could not be monitored by the PLC" A motion command has been started and has been buffered and confirmed by the NC. The PLC has not been able to monitor the execution of this command and the execution status is unclear since the NC is already executing a more recent command. The execution state is unclear.
This error may come up with very short buffered motion commands which are executed during one PLC cycle. 4B62 19298 Monitoring "Buffered command was terminated with an error" A buffered command was terminated with an error. The error number is not available, because a new command is already being executed. 4B63 19299 Monitoring "Buffered command was completed without feedback" A buffered command was completed but there was no feedback to indicate success or failure. 4B64 19300 Monitoring " 'BufferMode' is not supported by the command" The 'BufferMode' is not supported by this command.
4B65 19301 Monitoring "Command number is zero" The command number for queued commands managed by the system unexpectedly has the value 0.
