Sts Container Cranes With Camera Measuring System - Siemens SIMOTION D4x5-2 DP/PN Operating Instructions Manual

2.2.2.2

STS container cranes with camera measuring system

When the camera measuring system is used, sway motion or rotation of the spreader caused
by external factors (e.g. wind or diagonal pull) can also be detected. This measuring system
uses optical non-contact measurement to determine the distance between camera and
reflector, pendulum deflection and rotation of the spreader. The closed-loop control system can
eliminate the swaying motion and rotation based on the measured values.
If the measuring signal of the camera measuring system fails, only the mathematical calculation
model is used.
Note
For additional information, please refer to the operating instructions for the SIMOCRANE
CenSOR camera measuring system [Ref. 1].
A target generator which specifies the targets semi-automatically during loading and unloading
is also available. Targets for the semi-automatic mode (SAM) can be input either by the target
generator or via the PLC interface.
A detailed description of the STS functions can be found in Chapter Sway Control function
description (Page 147).

TLS system
STS cranes can be equipped with a TLS system. This system makes it possible to rotate the
spreader around all three axes (Trim, List, Skew). These rotations are implemented by four
hydraulic cylinders in most cases. An additional electric system can be used for skew damping.
You will find detailed information in Chapter TLS control function description (Page 237).
