Notes:

- All safety functions where a safe encoder isn’t required can achieve SIL3 (AKD2G FS option 2 and 3).

- All safety functions where a safe encoder is required are limited by the safety level of the installed / supported encoder.

- Current SMM version of AKD2G FS option 3 supports only one HDSL (Hiperface Digital Ssubscriber Line) safe encoder rated for SIL2 which is installed on AKM2G motors. https://en.wikipedia.org/wiki/High-bit-rate_digital_subscriber_line

 

Overview - Functional Safety with a KAS-Based System

image 

KAS systems include the PCMM motion/machine controller, SCU safety controller, AKD2G servo drive with safety card (FS2 and FS3 model), and optional AKT2G Safety I/O

  • EtherCAT FSoE (Fail Safe Over EtherCAT) is incorporated
  • Safety Configuration can be set up in either the AKD2G drive via Workbench or the SCU Controller via SafePLC2 programming software (for SCU safety controller)

Overview - Systems with AKD2G with an external controller

image

The AKD2G with functional safety can be used in a safety control system with an external controller. Options for connections between the AKD2G and an external controller are:

  • EtherCAT FSoE (Fail Safe Over EtherCAT). The safety configuration can be set up in either in the AKD2G Drive via Workbench or the external controller (if supported)
  • Discrete IO connections
