(10) Step width
Step width determines the distances the axis is to cover while
jogging. At a value of 0, the axis can be jogged steplessly. This
means that the axis continues moving in the relevant direc-
tion until the button is pressed or until the axis limit switch is
reached.
If the value entered is greater than 0, the axis moves by exactly
this value in the relevant direction when the button is pressed.

Controls Explanation
The jog buttons can
be used to move
the servo by hand
in the "Automatic
OFF" mode. On the
one hand, the travel
width is determined
by the duration for
which the jog key
is pressed, and on
the other, by the
value set under "Step
width".
Limit switch reached
in negative direction.
It is not possible to
move the servo any
further in the negati-
ve direction.
(Button cannot be
used)
Limit switch reached
in positive direction.
It is not possible to
move the servo any
further in the positive
direction.
(Button cannot be
used)
Entering the over-
ride has a relative
influence on the
target speed of the
servo drive during the
station sequence.
Pressing the"Target
position by hand"
button moves the
machine to the target
position selected or
entered.
The servo terminates
travel once the target
position has been
reached or the button
is no longer being
pressed.
This button initiates
the servo homing
run. The servo moves
towards an end
position defined in
the program.
