2.3.4
Programmable feedrate override
Function
The programmable feedrate override can be used to change the velocity level of path and
positioning axes by means of a command in the part program.
A separate feedrate override can be programmed for positioning axes.
Programming
The feedrate override can be changed with the following commands:
OVR= ....
Feedrate change for path feedrate
F
OVRA[X1]= ...
Feedrate change for positioning feedrate
FA
The programmable range is between 0 and 200%.
The default setting is 100%.
Effectivity
Interface signals "Rapid traverse and feedrate override" (DB21, ... DBB6) and "Axis-specific
override active" (DB31, ... DBX1.7) do not apply to the programmable feedrate override. The
programmable feedrate override remains active when these signals are deactivated.
The active override is calculated from the product of the programmable feedrate override
and the feedrate override from the machine control panel.
The default setting is 100%. It is active if no feedrate override has been programmed or
following a
RESET
, if machine data:
MD22410 F_VALUES_ACTIVE_AFTER_RESET (F function active via
RESET
)
is not set.
OVR
is not active with
G33,G34,G35
.
