Spindle functions
10.1 Spindle control
The spindle can be started and stopped in the following state:
DB21.DBX35.7= 1
DB21.DBX35.6 = 1
DB21.DBX35.3 = 1
Note
If the spindle must be stopped when the program is running, then set the interface signal
DB3x.DBX4.3, "Feed stop/spindle stop" in the user PLC.
Additional settings:
MD11450 $MN_SEARCH_RUN_MODE
Bit 1 = 1
Direction of rotation (only for ShopTurn)
In the ShopTurn user interface, ensure that the direction of rotation of the spindle and C axis
is correctly displayed and when programming ShopTurn functions, that the correct direction
of rotation is executed. You must base these settings on the actual direction of rotation of the
spindle/C axis on the machine.
● If you use the functions cylinder surface transformation and face machining, then a
precondition is that the function was correctly commissioned.
See Cylinder surface transformation (TRACYL) under ShopTurn (Page 574)
● The direction of rotation of the spindle/C axis for the M function M3 that is displayed in the
ShopTurn interface is defined in part using machine data:
See: Defining the direction of rotation in Section: Setting-up ShopTurn cycles for turning
(Page 569)
● The spindle direction of rotation (M3/ M4) is assigned to the positive direction of rotation
of the C axis via the interface signal DB3n.DBX17.6. The bit defines whether M3 and C+
rotate in the same direction (= 0) or in opposite directions (= 1). The corresponding
setting options can be found in the following sections:
– Direction of rotation of counter-spindle Setting up the counterspindle under ShopTurn
– Direction of rotation of main spindle Setting-up ShopTurn cycles for turning (Page 569)

Automatic ASUB start after output of the action blocks (see also
MD11620 $MN_PROG_EVENT_NAME). Alarm 10208 is not output until the ASUB is
completed.
