Overview of NC errors TwinCAT 16 Version: 1.1 Error(Hex) Error(Dec) Error type Description 4244 16964 Parameter "Internal parameters for the compensation are invalid" (INTERNAL ERROR) Invalid internal parameters or start parameters of the lower-level generator. 4245 16965 Function "Compensation active" Start of compensation refused, because compensation is already active. It's also possible that the M/S axes are not active moved. Therefore an execution of the compensation is impossible. 4246 16966 Function "Compensation not active" Stop of compensation refused, because compensation is not active.
4247 16967 Function "Compensation type invalid" The type supplied for the section compensation is invalid. At the present time only compensation type 1 (trapezoidal velocity profile) is allowed. 4248 16968 Function "Axis address for compensation invalid" (INTERNAL ERROR) The address of the master of slave axis on which the section compensation is to act is invalid. This is an internal error. 4249 16969 Address "Invalid slave address" (INTERNAL ERROR) The slave address given for on-line coupling/decoupling is invalid. 424A 16970 Function "Coupling velocity invalid" The velocity of what is to become the master axis is 0, which means that on-line coupling is not possible.
424B 16971 Function "Coupling velocities not constant" The velocity of what is to become the master axis and the velocity of what is to become the slave axis are not constant, so that on-line coupling is not possible. 424C 16972 Parameter "Cycle time less than or equal to 0.0 is not allowed" A value less than or equal to 0.0 for the cycle time (Slave) is not allowed, since the cycle time is by definition strictly positive, and with a cycle time of 0.0, division will generate an FPU exception. 424D 16973 Function "Decoupling task not allowed" The slave axis is of such a type (e.g. a table slave) or is in such a state (master velocity 0) that on-line decoupling is not possible.
424E 16974 Function "Function not allowed" The function cannot logically be executed, e.g. some commands are not possible and not allowed for slave axes. 424F 16975 Parameter "No valid table weighting has been set" The weighting factor of each table is 0, so that no table can be read. 4250 16976 Function "Axis type, actual position type or end position type is not allowed" The start type for a positioning task in invalid. Valid start types are ABSOLUTE (1), RELATIVE (2), CONTINUOUS POSITIVE (3), CONTINUOUS NEGATIVE (4), MODULO (5), etc. It is also possible that the types for setting a new actual position or for travel to a new end position are invalid.
4251 16977 Function "Function not presently supported" An NC function has been activated that is currently not released for use, or which is not even implemented. This can be a command which is not possible or not allowed for master axes. 4252 16978 Monitoring "State of state machine invalid" (INTERNAL ERROR) The state of an internal state machine is invalid. This is an internal error.
