AKD2G Safety Parametrization Using FSoE with SCU-1-EC and PxMM / PCMM2G

The safety features in the AKD2G safety driveClosed In electrical engineering, a drive is an electronic device to provide power to a motor or servo. Control device for regulating the speed, torque and position of a motor. A unit controlling a motor using the current and timing in its coils. (Basic and Advanced) can be activated through either Fail Safe over EtherCATClosed Ethernet ofr Control Automation Technology. EtherCAT® is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT is to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. (FSoE) or digital input or both.

The source of activation is configured inside the safety parameters and it needs to match the system requirements.

This topic describes how to configure and enableClosed Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set.

Requirements

Hardware
  • SCU-1-EC (BBH FSoE Master).
  • Kollmorgen controller (AKD PDMM, PCMM, or PCMM2G).
  • AKD2G safety drive.

Software

Procedure

These steps are for safety parameterization via the directClosed The orientation components of a vector in space. method using the KAS-IDE and BBH SafePLC2 software.

  1. Create a PLCopenClosed A vendor -and product- independent worldwide association active in Industrial Control and aiming at standardizing PLC file formats based on XML.-based project in the KAS-IDE.
  2. Scan the EtherCAT network.
  3. Configure the safety modules for the AKD2G devices.
    • Choose either the SRA Parameters or SRA Parameters configure via WorkBench module, based on the application need.
  4. When using SRA Parameters, add the FSoEParamsInit function blockClosed A function block groups an algorithm and a set of private data. It has inputs and outputs. to the project.
    This function block enables the controller to read the safety parameters from the FSoE Master (SCU-1-EC) and write them to the AKD2G.
  5. Follow either of these procedures:
    If SafePLC2 is installed on the same computer, use Direct Method Connection.
    If SafePLC2 is installed on a different computer than the KAS-IDE, use Import Method Connection.
  6. Compile and download the SafePLC application to the BBH safety master (SCU-1-EC) and run the application.
  7. Compile the KAS-IDE project.
  8. Run the compiled KAS application.
  9. Execute the FSoEParamsInit function block when the application is ready and EtherCAT is in OP state.
