4.3.3 Teaching the intermediate positions
The SPC11 permits fast movement into up to two selectable
intermediate positions. The desired intermediate positions
are “taught” by manual movement or by shifting the move-
able mass and then saving. The “taught” intermediate posi-
tions can be approached during operation.
The intermediate positions can also be used as sensor posi-
tions, as the relevant output bit (O3...O4) supplies a 1-signal
for 50 ms when the intermediate positions are exceeded (see
section 4.4.4).
Prerequisites: The drive must be ready for operation. There must be a
0-signal at input bits I1...I4. In order that the teach pro-
cedure can be started with the buttons, the yellow AS-Inter-
face bus cable must
not be connected. The supply pressure
must be switched on or off, depending on the variant.
Variants Procedure
The supply pressure is
switched off The moveable mass can be brought into
the desired position very accurately by
hand during the teach procedure.
The supply pressure is
switched on The mass can be moved manually. Very
accurate positioning can, under certain
circumstances, be difficult and may take a
considerble amount of time.
The following section explains how to teach the intermediate
positions when the supply pressure is switched on. If you
wish to teach the intermediate positions with the supply pres-
sure switched off, you must proceed in exactly the same
manner. However, the mass will not start moving automati-
cally when the button is pressed
{
or
}
, but must be
brought into the desired intermediate position by hand. The
button
{
or
}
must still be pressed at the appropriate posi-
tion.
