Indexing axis

DB380x PLC → NCK control signals
DBX3002.0 Incremental
DBX3002.1 Shortest distance
DBX3002.5 Direction of rotation as for M4
DBX3003.0 Absolute, negative direction
DBX3003.1 Absolute, positive direction
DBD3003.7 Indexing position
DBD3004 Setpoint position/setpoint distance
DBD3008 Feedrate velocity
DBX3000.7 Start positioning axis
DBX2.2 Delete distance-to-go, spindle reset
DB390x NCK → PLC status signals
DBX3000.7 Positioning axes active
DBX3000.6 Position reached
DBX3000.1 Error
DBB3003 Error number
DBX1.4 Axis/spindle stationary
1180
Valid
Remark
values
0|1 Only one of the bits must be set, if all bits are 0, then this
means absolute positioning.
0|1
0
0|1
0|1
1 Indexing axis ON
DINT for "incremental": Setpoint distance
REAL if = 0, the value is taken from machine data
POS_AX_VELO (unit as set in machine data).
0|1 Reset does not result in a stop!
0|1 Interrupt signal, exits the function
Remark
Also 1, if override = 0 or setpoint position reached.
1: Setpoint position reached with "Exact stop fine".
1: Error when traversing, evaluate error number in DBB3003!
