Components
After power has been applied, the stepping motor moves to the lower stop, connects to the valve
spindle and moves to the upper stop in the valve, thereby determining the closed position. Depending
on the control voltage, any stroke between 0 and 8 mm can then be obtained. Thanks to the
electronics unit, no steps can be lost, and the drive needs no periodical re-adjustment. Parallel
operation of more than one drive of the same type is guaranteed.
The feedback signal y
0
= 0...10 V corresponds to the effective stroke of 0 to 8 mm.
If the control signal (0...10 V) is interrupted and direction of operation 1 is connected, the valve closes
fully (0% position).
The valve’s characteristic can be selected using the coding switch. The characteristics can be
generated only if the drive is used as a continuous drive. Other switches enable the running times to
be set. These can be applied irrespective of which function (2-point, 3-point or continuous) has been
chosen.
