Actuator alignment electronics

The Actuator Alignment Electronics bases on the Airbus Defence and Space Universal Motor Control Electronics (MCE). This Electronics unit performs steering of up to three mechanical axis independently from each other and reports actual positions from Sensor Interfaces (configurable to reference switches, potentiometers and optical encoders). Autonomous operation to single commands.
