H1: Manual and handwheel travel
4.6 Handwheel travel
Travel command
Depending on the setting in machine data MD11324
$MN_HANDWH_VDI_REPRESENTATION (see Section "Parameter assignment
(Page 173)"), the following interface signal is output to the PC already when a travel request
is present or not until the axis moves:
● Machine axes:
– DB31, ... DBX64.6 (minus travel command) or
– DB31, ... DBX64.7 (plus travel command)
● Geometry axis 1:
– DB21, ... DBX40.6 (geometry axis 1: Minus travel command) or
– DB21, ... DBX40.7 (geometry axis 1: Plus travel command)
● Geometry axis 2:
– DB21, ... DBX46.6 (geometry axis 2: Minus travel command) or
– DB21, ... DBX46.7 (geometry axis 2: Plus travel command)
● Geometry axis 3:
– DB21, ... DBX52.6 (geometry axis 3: Minus travel command) or
– DB21, ... DBX52.7 (geometry axis 3: Plus travel command)
● Orientation axis 1:
– DB21, ... DBX332.6 (orientation axis 1: Minus travel command) or
– DB21, ... DBX332.7 (orientation axis 1: Plus travel command)
● Orientation axis 2:
– DB21, ... DBX336.6 (orientation axis 2: Minus travel command) or
– DB21, ... DBX336.7 (orientation axis 2: Plus travel command)
● Orientation axis 3:
– DB21, ... DBX340.6 (orientation axis 3: Minus travel command) or
– DB21, ... DBX340.7 (orientation axis 3: Plus travel command)
Note
A travel command set in JOG mode is canceled if the controller enable or pulse enable for the
axis to be traversed is missing. The travel command must therefore be set again after release
of the axis.
Invert handwheel direction of rotation
The handwheel direction of rotation can be inverted, if the direction of movement of the
handwheel does not match the expected direction of motion of the axis. The adaptation can
be especially necessary, if a handwheel (HT2, HT8) can be assigned to various axes.
