NC Error Codes Diagnostics 72 Version: 1.0 Error(Hex) Error(Dec) Error Type Description 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.
4253 16979 Monitoring "Reference cam became free too soon" During the referencing process for an axis it is moved in the direction of the referencing cam, and is only stopped again when the cam signal is reached. After the axis has then also physically stopped, the referencing cam must remain occupied until the axis subsequently starts back down from the cam in the normal way.
4254 16980 Monitoring "Clearance monitoring between activation of the hardware latch and appearance of the sync pulse" When the clearance monitoring is active, a check is kept on whether the number of increments between activation of the hardware latch and occurrence of the sync pulse (zero pulse) has become smaller than a pre-set value. This error is generated when that happens. (See parameters for the incremental encoder) 4255 16981 Memory "No memory available" The dynamic memory allocation for the set value generator, the SVB table or the SAF table has failed.
4256 16982 Monitoring "The table slave axis has no active table" Although the table slave axis has tables, none of the tables is designated as active. If this occurs during the run time the whole master/slave group is stopped by a run time error. 4257 16983 Function "Function not allowed" The requested function or the requested task is not logically allowed. An example for such an error message would be "set an actual position" for an absolute encoder (M3000, KL5001, etc.).
