H1: Manual traversing
17.5 Incremental manual traversing
● Orientation axis 2:
– DB21, ... DBX336.6 (orientation axis 2: Travel command "minus") or
– DB21, ... DBX336.7 (orientation axis 2: Travel command "plus")
● Orientation axis 3:
– DB21, ... DBX340.6 (orientation axis 3: Travel command "minus") or
– DB21, ... DBX340.7 (orientation axis 3: Travel command "plus")
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.

Parameter assignment

Fixed increments
The parameter assignment of the fixed increment sizes is performed via NC-specific machine
data:
MD11330 $MN_JOG_INCR_SIZE_TAB[1 ... 5] = <number of increments 1 ... 5>
Variable increment
The parameter assignment of the variable increment size is performed via NC-specific setting
data:
SD41010 $SN_JOG_VAR_INCR_SIZE = <number of increments>
Distance evaluation of one increment
The distance evaluation of one increment for fixed and variable increment sizes is performed
via the axis-specific machine data:
MD31090 $MA_JOG_INCR_WEIGHT = <distance>
Note
Reversal of the direction evaluation
The input of a negative value causes a reversal of the direction evaluation of the traversing keys
or the handwheel direction of rotation.
