Spindle Positioning - Siemens SINUMERIK 828D Function Manual

The following is required in order to use the functions:
• 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.

Remark
values
0|1 Only one of the bits must be set, if all bits are 0, then this
means absolute positioning.

0|1
REAL for "incremental": Setpoint distance
REAL If = 0, the value from MD35300
$MA_SPIND_POSCTRL_VELO (position control
activation speed) is taken
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!
1: if n < n
