Overview of NC errors TwinCAT 26 Version: 1.1 Error(Hex) Error(Dec) Error type Description 42DC 17116 Monitoring "Internal error by using Motion Function (MF)" An internal error occurs by using the Function (MF). This error cannot be solved by the user. Please ask the TwinCAT Support. 42DD 17117 Function "Axis coupling with synchronization generator declined because of incorrect axis dynamic values" The axis coupling with the synchronization generator has been declined, because one of the slave dynamic parameter (machine data) is incorrect (e.g.
the maximum velocity, the acceleration, the deceleration or the jerk is smaller or equal to zero, or the expected synchronous velocity of the slave axis is higher as the maximum allowed slave velocity. 42DE 17118 Function "Coupling conditions of synchronization generator incorrect" During positive motion of the master axis it has to be considered, that the master synchronous position is larger than the master coupling position ("to be in the future"). During negative motion of the master axis it has to be considered that the master synchronous position is smaller than the master coupling position.
42DF 17119 Monitoring "Moving profile of synchronization generator declines dynamic limit of slave axis or required characteristic of profile" One of the parameterized checks has recognized an overstepping of the dynamic limits (max. velocity, max. acceleration, max. deceleration or max. jerk) of the slave axis, or an profile characteristic (e.g. overshoot or undershoot in the position or velocity) is incorrect. See also further messages in the windows event log and in the message window of the System Manager. 42E0 17120 Parameter "Invalid parameter" The encoder generator parameter is not allowed.
42E1 17121 Parameter "Invalid parameter" The external (Fifo) generator parameter is not allowed. 42E2 17122 Function "External generator is active" The external generator cannot be started, as it is already active. 42E3 17123 Function "External generator is not active" The external generator cannot be stopped, as it is not active. 42E4 17124 Function "NC-Block with auxiliary axis violates software limit switches of the group" At least one auxiliary axis with active software limit monitoring has violated the limit switches. Therefore the geometric entry is denied with an error.
42E5 17125 Function "NC-Block type Bezier spline curve contains a cusp (singularity)" The Bezier spline curve contain a cusp, i.e. at a certain interior point both the curvature and the modulus of the velocity tend to 0 such that the radius of curvature is infinite. Note: Split the Bezier curve at that point into two Bezier spline curves according to the de "Casteljau algorithm". This preserves the geometry and eliminates the interior singularity. 42E7 17127 Parameter "Value for dead time compensation not allowed" The value for the dead time compensation in seconds for a slave coupling to an encoder axis (virtual axis) is not allowed.
