NC Error Codes Diagnostics 68 Version: 1.0 Error(Hex) Error(Dec) Error Type Description 4219 16921 Function "The scaling mode MASTER-AUTOOFFSET is invalid because no reference table was found". The used scaling mode MASTER-AUTOOFFSET is invalid in this context because an existing reference table is missing. This error can occur for example when adding cam tables without a unique reference to an existing cam table. 421A 16922 Parameter "The master axis start position does not permit synchronization" When a slave axis is being coupled on, the position of the master axis does not permit synchronization at the given synchronization positions.
421B 16923 Parameter "Slave coupling factor (gearing factor) of 0.0 is not allowed" A master/slave coupling with a gearing factor of 0.0 is being created. This value is not allowed, since it does not correspond to any possible coupling, and division will generate an FPU exception. 421C 16924 Function "Insertion of master axis into group not allowed" A master axis is to be inserted into a group at a location that is already occupied by another master axis. Maybe the reconfiguration cannot be done, because this axis has got an existing slave coupling. This master/slave coupling must be revoked before.
421D 16925 Function "Deletion of master axis from group not allowed" (INTERNAL ERROR) A master axis is to be removed from a location in a group that is not in fact occupied by master axis. 421E 16926 Function "Function/feature is not supported from the setpoint generator A function or feature is not supported from the setpoint generator (e.g. PTP master setpoint generator). This can be in general or only in a special situation. 421F 16927 Initialization "Group initialization" Group has not been initialized. Although the group has been created, the rest of the initialization has not been performed (1. Initialization of group I/O, 2. Initialization of group, 3. Reset group).
4220 16928 Monitoring "Group not ready / group not ready for new task" The group is being given a new task while it is still in the process of executing an existing task. This request is not allowed because it would interrupt the execution of the previous task. The new task could, for instance, be a positioning command, or the "set actual position" function. Precisely the converse relationships apply for the "set new end position" function. In that case, the group/axis must still be actively moving in order to be able to cause a change in the end position.
4221 16929 Monitoring "Requested set velocity is not allowed" The value requested for the set velocity of a positioning task is less than or equal to zero, larger than the "maximum velocity" (see axis parameters), or, in the case of servo-drives, is larger than the "reference velocity" of the axis (see drive parameters). 4222 16930 Monitoring "Requested target position is not allowed (master axis)" The requested value for the target position of a positioning task is not within the software end locations. In other words, it is either less than the minimum software end location or larger than the maximum software end location.
This check is only carried out if the relevant end position monitoring is active.
