Programming And Activating Handwheel Override - Siemens SINUMERIK Series Function Manual

NC Stop/override = 0
If the feedrate override is set to 0% or an NC Stop is initiated while the handwheel override is
active, the following applies:
● For path definition:
● For velocity specification:

Programming and activating handwheel override

General information
When the handwheel override is programmed with NC language elements
and
●
● When the handwheel override is activated with

● The positioning axis must not be an indexing axis.

The handwheel pulses arriving in the meantime are summated and stored. If NC Start or
the feedrate override > 0%, the saved handwheel pulses become effective (i.e. are
traversed).
However, if the handwheel is first deactivated [via IS DB21, ... DBX12/16/20.0-2
(geometry axes 1/2/3: Activate handwheel (1, 2, 3))] then the stored handwheel pulses
are deleted.
The handwheel pulses arriving in the meantime are not summated and are not active.

programmed in the NC block for the positioning axis or for a path axis. When the
programmed target position is reached, the handwheel override becomes inactive again.
