H1: Manual and handwheel travel
3.5 Handwheel override in automatic mode
Extended Functions
170 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
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.
If block
POS[A]=100 FDA[A]=0 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 1 used twice (6) in channel 1 axis A) is signaled.
If machine axis 4 is traversed with DRF, then no
POS[A]=100 FDA[A]=0 movement can be
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.
3.5 Handwheel override in automatic mode
3.5.1 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
FD (for path axes) and FDA (for positioning axes) and is non-modal.
With positioning axes, it is possible to activate the handwheel override modally using
traverse command
POSA. When the programmed target position is reached, the handwheel
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.
