Example: Velocity override of positioning axis
Assumption:
Channel 1: Channel axis A corresponds to machine axis 4 and handwheel 1 is assigned to
this axis.

traversed with DRF. This means that if the channel-specific DRF signal is active, alarm
14320 (Handwheel 1 used twice (6) in channel 1 axis A) is signaled.
If machine axis 4 is traversed with DRF, then no
executed while a DRF movement is being performed. Alarm 14320 (Handwheel 1 used twice
(1) in channel 1 axis A) is signaled.
Example: Distance overlay PLC axis (840D sl)
Assumption:
Channel 1: Handwheel 2 is assigned to machine axis 4.
If an axis movement with path override of the 4th machine axis triggered by FC18 is
processed in the main run, machine axis 4 cannot be traversed with DRF. This means that if
the channel-specific DRF signal is active, alarm 14320 (Handwheel 2 used twice (9) in
channel 1 axis A) is signaled.
If machine axis 4 is traversed with DRF, then no axis movement with path override triggered
by FC18 can be executed while a DRF movement is being performed. Alarm 14320
(Handwheel 2 used twice (4) in channel 1 axis A) is signaled.

General functionality

Function
With this function it is possible to traverse axes or to change their velocities directly with the
handwheel in automatic mode (Automatic, MDA).
The handwheel override is activated in the NC part program using the NC language
elements
With positioning axes, it is possible to activate the handwheel override modally using
traverse command
override becomes inactive again.
Additional axes can be traversed simultaneously or using interpolation in the same NC block.
The concurrent-positioning-axes function can also be activated by the PLC user program.
