Force reduction G925
G925 activates/deactivates the force reduction. When the monitoring
is activated, the maximum contact force for one axis is defined. Force
reduction can be activated for only one axis per NC channel.
The G925 function limits the contact force for subsequent movements
of the defined axis. G925 does not execute any traverse.
The machine tool builder determines the scope of function
and behavior of G925. The machine manual provides
further information.
Parameters
H Contact force [dN] – The contact force is limited to the given
value
Q Axis number (X=1, Y=2, Z=3, U=4, V=5, W=6, A=7, B=8,
C=9)
S Sleeve monitoring
 0: Deactivate (do not monitor the contact force)
 1: Activate (the contact force is monitored)
Lag error monitoring is not activated until the acceleration
phase has been completed.
