counterclockwise rotation.
►
Program the counterclockwise rotation: In the
CellClutch
PC software, set the
Rotation
to
Reverse
in the
Forward and Reverse Application
Settings
and parameterize the
Speed
.
If
Forward
is selected for
Enabled Direction
, the
counterclockwise rotation of the
reverse switch has no function.
Tool does not start with coun-
terclockwise rotation activated.
With counterclockwise rotation,
parameter for Speed is 0 rpm.
►
Program the speed for counterclockwise rotation:
In the
CellClutch
PC software, set the
Speed
and
Rotation
in the
Forward and Reverse Appli-
cation Settings
.
Tool shuts off prematurely.
Operator releases start trigger
before the controller stops the
