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:

How does an observer work?

The observer will create an estimate of system velocity that is derived from the measured Velocity Feedback and the integral of the Current command. The velocity estimate is frequency-dependent. At frequencies below the observer bandwidth the estimate is determined by the measured feedback and at frequencies above the observer bandwidth, it will be determined by the integral of the current command and will be a combination of the 2 at the observer bandwidth.
