Automatic Selection And Deselection Of Position Control - Siemens SINUMERIK Series Function Manual

13.2.4

Automatic selection and deselection of position control

Behavior in speed control mode
In DV coupling mode, program instructions
activate and/or deactivate position control for the leading spindle as required. If there are
several following spindles on the leading spindle, then in speed-controlled mode, the first
DV activates coupling position control for the leading spindle and the last DV coupling
deactivates coupling position control for the leading spindle if SPCON is not programmed.
The leading spindle does not need to be located in the same channel as the following
spindle.
Automatic selection with COUPON and COUPONC
Depending on the coupling type, the effect of
synchronous operation is as follows:
Coupling type
Following spindle FS
Leading spindle LS
The position control is activated by a
