SCALEXIO TWINsync Solution

Synchronous load motor control for test benches with dSPACE SCALEXIO

The SCALEXIO TWINsync Solution makes it possible to control multiple electrical drives synchronously with a SCALEXIO system.

In some HIL test cases, it is possible to access the electronic control unit (ECU) not only by its electrical interfaces. It it also possible to have mechanical access via electric load machines that mechanically simulate a passenger car’s steering wheel as a human-machine interface, for example. Depending on the requirements and applications, different load machines are used, such as rotary drives, spindle actuators, and highly dynamic linear motors. To deliver the desired values for these load machines in real time, a high synchronicity between the HIL simulator and the load machine controller is indispensable. 

Key Benefits

The SCALEXIO TWINsync Solution provides an interface for the proprietary TWINsync protocol from KEBA (formerly LTi Motion GmbH), thus enabling highly dynamic control of one or more LTi ServoOne motor controllers. Thanks to the installed IOCNET connection, full synchronicity of the connected load motor control can be achieved even in large test facilities at a distance of up to 100 m from the HIL simulator. The associated blockset makes it easy to configure the SCALEXIO TWINsync solution in ConfigurationDesk.

With the SCALEXIO TWINsync hardware, two or more load motor controllers can be controlled via HIL simulation.

SCALEXIO:
Powerful and flexible dSPACE hardware-in-the-loop simulator

SCALEXIO TWINsync hardware:
External housing with a DS2656 FPGA Base Board and a DS5451 Custom I/O Module as the interface to the TWINsync components. The IOCNET connection makes it possible to use TWINsync hardware up to 100 m from the SCALEXIO simulator.

LTi ServoOne:
Compact, high-performance motor control by LTi Motion GmbH for a high number of linear and rotary load motor systems from 2 to 450 ampere
