Dark phase

Time between closing the lamellae and falling into the shadowing position. In case of actuators of Venetian blinds with final position detectors, the dark phase is very short, since the final position is identified directly.

Detection of the final position

Automatic identification of the limit switch in the motor. The delay is calibrated by this and falls immediately after reaching the lower stop position or it will signal error detection. By the permanent calibration, Ächanges are identified and compensated for in the motor (e.g. Ächanges in speed due to thermal differences, weathering etc.).

Detection of the limit switch

Not used any more. Refer to final position detection (Reason: The switch need not be compulsorily detected …).

DP

Transparent position (corresponds to P4)

Drive command

Generic term for commands, which actuate a drive motion on the motor (Start, Shut, P1, P2, P3, P4, see-saw, Height, Angle).

Driving strategy

Sequence of movements in order to ensure that the supporting material stays properly and constantly returns to the target position.
