Overview of NC errors TwinCAT 11 Version: 1.1 Error(Hex) Error(Dec) Error type Description 4202 16898 Initialization "Master axis index not allowed" The value for the master axis index in an interpolating 3D group is not allowed, because, for instance, it has gone outside the value range. Index 0: X axis (first master axis) Index 1: Y axis (second master axis) Index 2: Z axis (third master axis) Value range: [0, 1, 2] Unit:
1 4203 16899 Initialization "Slave axis index not allowed" (INTERNAL ERROR) The value for the slave axis index in a group is not allowed, because, for instance, it has passed outside the value range, the slave location to be used when inserting a new slave connection is already occupied, or because no slave is present when such a connection is being removed. Index 0: First slave axis Index 1: Second slave axis Index 2: etc. Value range: [0 ... 7] Unit:
1 4204 16900 Initialization "INTERNAL ERROR" (GROUPERR INTERNAL) _ 4205 16901 Parameter "Invalid cycle time for statement execution task (SAF)" The value of the cycle time for the NC block execution task (SAF 1/2) is not allowed, because it has passed outside the value range. Value range: [0.001 ... 0.1] Unit: s 4206 16902 Initialization „GROUPERR RANGE MAXELEMENTSINAXIS “ _ _ 4207 16903 Parameter "Invalid cycle time for the statement preparation task (SVB)" The value of the cycle time for the NC statement preparation task (SVB 1/2) is not allowed, because it has passed outside the value range. Value range: [0.001 ... 1.0] Unit:
s 4208 16904 Parameter "Single step mode not allowed" The flag for the activation or deactivation of single step mode is not allowed. Value 0: Passive (buffered operation) Value 1: Active (single-block operation) Value range: [0, 1] Unit: 1 4209 16905 Parameter "Group deactivation not allowed" (INTERNAL ERROR) The flag for the deactivation or activation of the complete group is not allowed. Value 0: Group active Value 1: Group passive Value range: [0, 1] Unit: 1 420A 16906 Initialization "Statement execution state (SAF state) not allowed" (INTERNAL ERROR) The value for the state of the block execution state machine (SAF state) is not allowed.
This error occurs on passing outside the range of values, or if the state machine enters an error state. Value range: [0 ... 5] Unit: 1 420B 16907 Address "Channel address" The group does not have a channel, or the channel address has not been initialized. 420C 16908 Address "Axis address (master axis)" The group does not have a master axis (or axes) or the axis address(es) has (have) not been initialized. 420D 16909 Address "Master axis address" A new master/slave coupling is to be inserted into the group, but there is no valid address for the leading master axis.
420E 16910 Address "Slave axis address" A master/slave coupling is to be inserted into the group, but there is no valid address for the slave axis. 420F 16911 Address "Slave set value generator address" A master/slave coupling is to be inserted into the group, but there is no valid address for the slave set value generator.
