H1: Manual and handwheel travel
4.6 Handwheel travel
Traversing
When the electronic handwheel is turned, the associated axis is traversed either in the positive
or negative direction depending on the direction of rotation.
Note
If the axis is already being moved using the traversing keys, the handwheel cannot be used.
Traversing distance
The traversing distance produced by rotating the handwheel is dependent on the following
factors:
● Number of handwheel pulses received at the interface
● Active increment (machine function INC1, INC10, INC100, ... INCvar)
● Pulse evaluation of the handwheel:
MD11320 $MN_HANDWH_IMP_PER_LATCH (handwheel pulses per detent position)
See Section "Parameter assignment (Page 173)".
● Distance of an increment:
MD31090 $MA_JOG_INCR_WEIGHT (evaluation of an increment for INC/handwheel)
See Section "Parameter assignment (Page 173)".
Handwheel connection
Up to six handwheels can be connected simultaneously. This means that up to six axes can
be traversed by handwheel simultaneously.
Representation of the handwheel number in the NC/PLC interface signals
Depending on the parameter assignment of MD11324, the representation of the handwheel
number in the NC/PLC interface signals is bit-coded (three handwheels can be represented)
or binary-coded (six handwheels can be represented).
See Chapter "Parameter assignment (Page 173)".
Handwheel assignment
The axis that is moved by turning the handwheel can be set via the via the PLC user interface
or via the user interface (HMI). The assignment is linked to the NC/PLC interface through the
PLC user program. In this way, several axes can be assigned to one handwheel
simultaneously.
