Overview of NC errors TwinCAT 46 Version: 1.1 Error(Hex) Error(dec) Error type Description 4B07 19207 Parameter "Timeout axis function block" After positioning, all "MC Move..." blocks check whether _ positioning was completed successfully. In the simplest case, the "AxisHasJob" flag of the NC axis is checked, which initially signifies that positioning was logically completed. Depending on the parameterization of the NC axis, further checks (quality criteria) are used: • "Position range monitoring" If position range monitoring is active, the system waits for feedback from the NC. After positioning, the axis must be within the specified positioning range window.
If necessary, the position controller ensures that the axis is moved to the target position. If the position controller is switched off (Kv=0) or weak, the target may not be reached. • "Target position monitoring" If target position monitoring is active, the system waits for feedback from the NC. After positioning, the axis must be within the specified target position window for at least the specified time. If necessary, the position controller ensures that the axis is moved to the target position. If the position controller is switched off (Kv=0) or weak, the target may not be reached.
Floating position control may lead to the axis oscillating around the window but not remaining inside the window. If the axis is logically at the target position (logical standstill) but the parameterized position window has not been reached, monitoring of the above-mentioned NC feedback is aborted with error 19207 (0x4B07) after a constant timeout of 6 seconds. 4B08 19208 Parameter "Axis is in protected mode" The axis is in protected mode ( e.g. coupled) and cannot be moved. 4B09 19209 Parameter "Axis is not ready" The axis is not ready and cannot be moved. 4B0A 19210 Parameter "Homing error" Referencing (homing) of the axis could not be started or was not successful.
4B0B 19211 Parameter "Incorrect definition of the trigger input" The definition of the trigger signal for block MC TouchProbe is _ incorrect. The defined encoder-ID, the trigger signal or the trigger edge are invalid. 4B0C 19212 Function "Position latch was deactivated" The block MC TouchProbe has detected that a measuring probe _ cycle it had started was deactivated. The reason may be an axis reset, for example. 4B0D 19213 Function "NC status feedback timeout" A function was successfully sent from the PLC to the NC. An expected feedback in the axis status word has not arrived.
4B0E 19214 Function "Supplement not installed" The function is available as an supplement but is not installed on the system. 4B0F 19215 Function "No NC Cycle Counter Update" – The NcToPlc Interface or the NC Cycle Counter in the NcToPlc Interface was not updated. Error numbers 0x4B10 to 0x4B2F are used in the TwinCAT NCI context: 4B10 19216 Function "M-function query missing" This error occurs if the M- function was confirmed, but the request bit was not set.
