Axis/spindle disable" DB31, ... DBX1.3
Activating "Axis/spindle disable" (DB 31, ...DBX1.3) disables the axial PLC interlocks
"No controller enable" and "Feed stop".
The axial and channel-specific override, however, is active.
"Spindle stop" DB31, ... DBX4.3
IS "Spindle stop" (DB31, ... DBX4.3) is used to stop the relevant spindle.
Activation of the "Spindle stop" function
If G33, G34, G35 active: Effective
(may cause contour deviations depending on
dynamic characteristics)
If G63 active: Effective
If G331, G332 active: Not effective
2.3.3 Feedrate override on machine control panel
General
The operator can use the feedrate override switch to increase or decrease the path feedrate
relative to the programmed percentage with immediate effect. The feedrates are multiplied
by the override values.
An override between 0 and 200% can be programmed for the path feedrate.
The rapid traverse override switch is used to reduce the traversing velocity when testing a
part program.
An override between 0 and 100% can be programmed for the rapid traverse.
The feedrate can be changed axis-specifically for positioning axes. The override can be
between 0 and 200%.
The spindle override can be used to modify the spindle speed and the cutting rate (with G96,
G961). The override can be between 0 and 200%.
The override is not permitted to exceed the machine-specific acceleration and speed limits or
generate a contour error.
The feedrate override can be changed separately for path and positioning axes.
The overrides act on the programmed values or on the limits (e.g., G26, LIMS for spindle
speed).
A sequence of G63 blocks is traversed without taking into account the feedrate override. A
sequence of G63 blocks consists of directly consecutive blocks with G code G63. It starts
with the first G63 block and finishes with the first path motion block, which is not a G63 block.
