The new control generation MultiControl II – high-performance products that come with smart features

Flexible, suitable for global use, backwards compatible and easy to service

With the MultiControl II drive control, RK Rose+Krieger GmbH supplies a high-performance controller for the company's wide range of electrical lifting columns. In particular the premium version of the controller can be used to position multiple table surfaces and monitor surfaces independently of each other – despite different drive types. Previously multiple controllers were required.

Software functions of the Multicontrol II Basic / Premium

The MultiControl II control is available in a Basic and a Premium version. The Premium version includes three additional software functions (described below) compared to the Basic version.

 
Collision protection for lifting columns

SPP is a software-based collision detection solution

SPP – Smart Product Protection (integrated collision detection)

The Premium version of the MultiControl II unit incorporates RK Rose+Krieger GmbH’s proprietary SPP technology. This technology considerably reduces the risk of product damage in the customer’s application. Protection is provided not just for the connected drives, but also for the adjoining set-up as a whole.
When adjusting the height of tables or machine frames, for instance, there is a latent risk of collisions as a result of raising and lowering a load. If such collisions occur, they can cause damage to drives (reduced service life and the possibility of complete failure) but also the adjoining set-up, or may cause obstructions.

SPP is a software-based solution for collision detection. A major benefit is that the technology is fully integrated into the control system, which means that the customer application does not need to be equipped with any additional external sensors.
A further special feature is that the customer is able to adjust the sensitivity of the system (actuation force when a collision is detected) to suit the specific application. The key advantages of integrated collision detection are summarised below.

 
Relative and absolute positioning of lifting column applications

Relative and absolute positioning of lifting column applications

Relative and absolute positioning

Alongside the integrated collision detection (SPP), the Premium version has two further functions which relate to the type of drive positioning.
In addition to approaching previously stored memory positions, relative or absolute positioning can now be carried out too. The first of these enables positioning relative to the current position of the lifting column. The operator control can thus be used to set a defined value (e.g. 30% or 30 mm) by which the drive further retracts or extends.

Absolute positioning, on the other hand, utilises the complete scale of the adjustment range. So the operator control can also be used to move the drive precisely to a predefined position. This function can be very important for applications in which components are measured, for example.

 
Drive group management

Drive group management – the easy way to move lifting columns individually or in groups

Drive group management (DGM)

The Basic version of the MultiControl II quadro allows you to position four drives synchronously. If this functionality is not sufficient, you can choose the Premium version of the control unit,
which features drive group management alongside the familiar collision detection 8SPP). This function, which was developed in-house by RK Rose+Krieger, allows different drive groups to be freely configured (2+2, 2+1, 1+2 and 1+1). Two different drive types (e.g. RK Slimlift and Multilift II) can be combined or operated individually, in parallel or synchronously.
