Spindle functions
10.2 Analog spindle
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

Function Manual, Basic Functions; Spindles (S1)
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) (Page 544)
● 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 533)
● The direction of spindle rotation (M3 / M4) is assigned to the positive rotational direction of
the C axis via interface signal DB31, ... 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 533)

Machine axis index for analog spindle
For an analog spindle, the utilization display can be controlled via PLC.

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.
