Spindle Positioning - Siemens SINUMERIK 840D sl Function Manual

The following requirements must be satisfied in order to use the functions listed below:
● The axis or spindle is correctly assigned to the PLC.
● Controller and pulse enable are set.
● After setting all of the control signals, only one of the start signals is set in DB380x.DBB3000.

Valid val‐ Remark
ues
0|1 Only one of the bits must be set, if all bits are 0, then this
means absolute positioning.
0|1
0|1
0|1
REAL For "incremental": Setpoint distance
REAL If = 0, the value from MD35300
$MA_SPIND_POSCTRL_VELO (position control activa‐
tion speed) is taken
0|1 Reset does not result in a stop!
0|1 Interrupt signal, exits the function
Remark
Also 1 when override = 0 or position setpoint reached
when start = 1
1: Position setpoint reached with "Exact stop fine"
1: Error during traversing, evaluate error number in DBB3003!
1: if n < n
