Electronic Control Units
The Moog 2-channel Electronic Control Unit (ECU) is comprised of 2 hybrid stepper motor controllers, an EMI filter, and 6 analog pass-throughs for telemetry. The ECU enclosure has been designed to allow 2 ECU’s to be stacked to form a 4-channel ECU. The ECU contains all power conditioning, pulse sequencing and output driver stages necessary to drive two 3-phase motors. The system electrical interface consists of power and command input lines, output motor drive lines and telemetry outputs. The required input commands are discrete for ENABLE and DIRECTION, and a pulse train on the STEP input. An initial discrete logi state on the ENABLE line will activate the control unit for the desired motor. On the DIRECTION line, one logic state enables clockwise rotation and the other state enables counterclockwise rotation. Motion is initiated by the application of a pulse train on the STEP command line.
