2.4 Supported Motor-Sensor Configurations
2.4.1 Single loop configurations
The position and/or speed are controlled using one feedback sensor. The other available feedback sensor input can
be used for External reference Position or Velocity, Pulse and Direction, Electronic Gearing or Camming.

2.4.2 Dual loop configurations
The motor speed control loop is closed on one feedback connected on the motor while the motor position control loop
is closed on the other available feedback which is placed on the load. There is usually a transmission between the
load and the motor.

Each defined motor type can have any combination of the supported feedbacks either on motor or on load.
Example: PMSM motor with Incremental encoder (from feedback #1) on motor and Incremental encoder (from
feedback#2) on load
