Handwheel assignment
The assignment of the connected handwheels to the axes is analogous to the "Handwheel
travel in JOG (Page 154)" via the user interface or via the PLC u
ser interface with one of the
following interface signals:
● Machine axes:
– DB31, ... DBX4.0-2 (activate handwheel (1, 2, 3))
● Geometry axes:
– DB21, ... DBX12.0-2 (geometry axis 1: Activate handwheel (1, 2, 3))
– DB21, … DBX16.0-2 (geometry axis 2: Activate handwheel (1, 2, 3))
– DB21, … DBX20.0-2 (geometry axis 3: Activate handwheel (1, 2, 3))
If handwheel override is programmed for an axis to which no handwheel is assigned, a
distinction is made between the following cases:
● For velocity override:
The axes traverse at the programmed velocity.
A self-acknowledging alarm is output (without response).
● For path definition:
No traversing movement is performed because the velocity is zero.
A self-acknowledging alarm is output (without response).
Note
When the velocity override is applied to path axes, only the handwheel of the 1st
geometry axis acts on the path velocity.
Handwheel weighting
The traverse path of the axis that is generated by rotating the handwheel by one detent
position is dependent on several factors (see Section "Handwheel travel in JOG
(Page 154)"):
● Selected in
crement size:
MD11330 $MN_JOG_INCR_SIZE_TAB[5] (increment size for INC/handwheel)
or
SD41010 $SN_JOG_VAR_INCR_SIZE (size of the variable increment for JOG)
● Weighting of an increment:
MD31090 $MA_JOG_INCR_WEIGHT
● Number of handwheel pulses per detent position:
MD11320 $MN_HANDWH_IMP_PER_LATCH
For example, the axis traverses by 0.001 mm per handwheel detent position if machine
function INC1 and the default setting of the above machine data are selected.
In the case of velocity override, the velocity results from the traverse path covered using the
handwheel within a certain period of time.
