Spindle Axis Mode - Siemens SINUMERIK 802D sl Function Manual

Spindle (S1)
20.2 Spindle modes
Phase 2: Acceleration has been performed up to the speed set in
MD35300 SPIND_POSCTRL_VELO (position control activation speed). The brake
application point calculation identifies when the programmed spindle position (SPOS=...) can
be approached with the acceleration defined in MD35210 GEAR_STEP_POSCTRL_ACCEL.
Phase 3 and Phase 4: The sequence for "Deceleration" and "Position reached" is the same
as for non-synchronized spindles.
Spindle reset
The positioning process can be aborted with the IS "Delete distancetogo/spindle reset"
(V380x 0002.2). However, the spindle remains in positioning mode.
Notes
● In positioning mode the spindle speed override switch continues to be valid.
● Positioning (SPOS) is cancelled with "Reset" or "NC stop".
20.2.4

Spindle axis mode

When axis mode?
For certain machining tasks on lathes: For face machining with TRANSMIT or peripheral
surface machining with TRACYL the spindle must be operated as rotary axis.
Outside of TRANSMIT and TRACYL, you can perform normal rotary axis functions. In this
case it is programmed under the address of the rotary axis, e.g. C.
Requirements
The spindle can be switched from spindle mode to axis mode (rotary axis) if the same motor
is used for spindle and axis operation.
A position actual value encoder is a mandatory requirement for axis mode.
Activate/deactivate
● Set spindle to position-controlled mode (positioning mode):
● If the spindle is synchronized, this can also be performed with M70 or SPCON. Traversal
● Return to speed-controlled spindle mode is performed with:
