General functionality

Selection
JOG mode must be active. The user must also set the increment INC1, INC10, etc., which
applies to handwheel travel. As with incremental travel, the required machine function must
be set at the PLC interface accordingly.
Traversing
When the electronic handwheel is turned, the associated machine axis is traversed either in
the positive or negative direction depending on the direction of rotation.
Traversing path
The traverse path 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 weighting of the handwheel using general machine data
● Weighting of an increment for INC/handwheel
Motion command +/-
During the axis movement, the
DB21, ... DBX40.7 (motion command +
or
DB21, ... DBX40.6 (motion command -)
interface signal is output to the PLC, depending on the direction of movement.
If the axis is already being moved using the traversing keys, the handwheel cannot be used.
Handwheel connection
Two handwheels can be connected simultaneously. In this way, up to two axes can be
traversed by handwheel simultaneously.
Exception: If several axes are assigned to one handwheel simultaneously, more than two
axes can be traversed with handwheels.
