7 BLOCKS DIAGRAM

Below is the blocks diagram of the motor control implemented in the the epsacw. It
is an Indirect Field Oriented Control but it can be turned to a sensorless motor
control (on demand).
There are three main steering modes that it is possible to adopt for a steer
application (and the blocks diagram of the external control loop will be one of three
according the adopted steering mode: see 7.1 - 7.2 - 7.3 below).

7.1 Speed Control Mode (Open Loop)

In a Speed Mode (Open Loop), the steering motor speed is proportional to the
speed of a tacho generator at the steering wheel. This is the one implemented
in the current application and dealt in this manual.
