SCALEXIO EMH Solution for Electric Drives Simulation

Processor based simulation of electric drives

The SCALEXIO EMH Solution provides a comprehensive ConfigurationDesk I/O library for the processor-based HIL simulation of electric drives.  

  • Processor-based simulation
  • Predefined function blocks
  • Ideal for PWM and PSS applications

The SCALEXIO EMH Solution enables easy processor-based simulation of electric drives.

Processor-Based Simulation of Electric Drives

The SCALEXIO EMH Solution can be used for defining the I/O functions for the simulation of up to two electric drives. The required FPGA base board (DS6601, DS6602 or DS2655) is configured from within ConfigurationDesk. Thanks to the predefined function blocks, users do not have to program or generate FPGA code. The DS2655M1 and DS6651 Multi-I/O Modules as well as the integrated angular processing units (APUs) enable the use of high-resolution I/O to support applications in the areas of position sensor simulation (PSS) and pulse width modulation (PWM). The variable I/O channel mapping and the flexible support of up to five DS2655M1 or up to five DS6651 Multi-I/O Modules open up the hardware’s full potential. If the drive controller requires an enhanced simulation resolution, a seamless switch to FPGA-based simulation is possible without changing the hardware. The EMH Solution FPGA design includes four internal APUs running on the FPGA base board to calculate the local position. Furthermore, up to six master APUs can be referenced globally as position sources via IOCNET. Each of the position sensors can be configured for allocating one of the ten APUs as the position source.

Depending on the number of DS2655M1 modules, the available amount of I/O channels varies.
