H1: Manual and handwheel travel
3.5 Handwheel override in automatic mode
Extended Functions
174 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
Example
Assumptions:
The operator turns the handwheel with 100 pulses/second.
The selected machine function is INC100.
The default setting is made for the above machine data for handwheel weighting.
⇒ Handwheel traverse path per second: 10 mm
⇒ Velocity override: 0.6 m/min
PLC interface signals
As soon as the handwheel override takes effect, the following interface signals to the PLC
are set to signal 1:
● For positioning axes / concurrent positioning axes / command axes / reciprocating axes:
DB31, ... DBX62.1 (handwheel override active)
● For path axes:
DB21, ... DBX33.3 (handwheel override active)
For the path input, depending on the traversing direction, the appropriate interface signals
are output to the PLC:
● Machine axes:
– DB31, ... DBX64.6/7 (traversing command minus/plus)
● Geometry axes:
– DB21, … DBX40.6/7 (geometry axis 1: traversing command minus/plus)
– DB21, … DBX46.6/7 (geometry axis 2: traversing command minus/plus)
– DB21, … DBX52.6/7 (geometry axis 3: traversing command minus/plus)
Limitations
The axial limitations (software limit switch, hardware limit switch, working-area limitation) are
effective in conjunction with handwheel override. With path default, the axis can be traversed
with the handwheel in the programmed traversing direction only as far as the programmed
target position.
The resulting velocity is limited by the axial machine data:
