This sample configuration illustrates setting up a dual-axis AKD2G with dual-axis KSM 12-2 Safety PLC. 

Safety Engineering is not so simple that one design will meet SIL2 for all applications. The intent of this document is to give a functional example of an AKD2G drive and KSM Safety PLC.

Implementation of STO Inputs

There are two types of STO input in common use today:

  1. DC-DC Type: isolated STO input based on using a DC-DC converter to power the date driver circuitry. 
  2. O-C Type: opto-isolated input of a drive that acts upon the gate driver circuit.

Here is a simplified drawing of an O-C Type input:
