This chapter describes the internal structure of the SimplIQ for Steppers. Please note
that SimplIQ for Steppers may have several hardware implementations, and the issues
discussed in this section may be dependent on the specific implementation.
2.1. The SimplIQ for Steppers Processor and
the Motion Processor

Figure 2-1: SimplIQ for Steppers processor and a motion processor
The SimplIQ for Steppers processor runs the command interpreter for all the
communication and programming types, and generates the command reference for
the motion processor.
The motion processor interfaces with the sensor and the power electronics, and
calculates the real-time control.
