General notes about the series

Repeat accuracy
is defined as a distribution of the end Position for 100 consecutive strokes.

Drive ring
The position of the drive ring is always drawn in basic position. From here, the ring turns clockwise or anti-clockwise.

Swiveling time
is the rotation time of pinion/flange around the nominal rotation angle. Valve switching times, hose filling times, or PLC reaction times are not included and are to be considered when cycle times are calculated.

Reference sensor
For monitoring the basic position, an inductive sensor can be attached, which will be actuated every 360°. It can be used for reference run or for checking if the control unit has counted correctly.

Swivel time depends on the payload
The shown diagrams are valid for nominal rotation angles, for the use with vertical swivel axis, or for centrical payloads with horizontal swivel axes, and at an operating pressure of 6 bar. The diagrams show the expected swivel time, and allows cycle per hour depending on the mass moments of inertia. The swiveling times need to be adjusted by using throttle valves, otherwise the life time could be reduced. We will be happy to help you designing other applications.

Total cycle time
The total cycle time consists of the swiveling time per cycle together with other required time intervals. See the operating manual for the exact calculation of the total cycle time.
