Abstract
An example actuator control system includes a variable differential transformer (VDT) configured to measure displacement of a motor, and a motor controller configured to control the motor based on displacement data from the VDT. A circuit card assembly (CCA) interconnects the VDT to the motor controller. The CCA includes memory storing configuration data of the VDT, and the CCA is configured to provide the configuration data to the motor controller to calibrate the motor controller for use of the VDT. A method of configuring a motor controller is also disclosed.
Claims20
An actuator control system, comprising:
- a variable differential transformer (VDT) configured to measure displacement of a motor;
- a motor controller configured to control the motor based on displacement data from the VDT;
- and
- a circuit card assembly (CCA) that is separate from the VDT and motor controller and that provides a communication link between the VDT and motor controller by interconnecting a signaling line of the VDT to a signaling line of the motor controller, the CCA comprising memory storing configuration data of the VDT, the CCA configured to provide the configuration data to the motor controller to calibrate the motor controller for use of the VDT.
An actuator system, comprising:
- an actuator;
- a plurality of motors configured to cooperatively operate the actuator;
- a plurality of variable differential transformers (VDTs), each configured to measure displacement of a respective one of the motors;
- a plurality of motor controllers, each configured to control a respective one of the motors based on data from the VDT associated with the motor;
- and
- a plurality of circuit card assemblies (CCAs), each separate from the plurality of VDTs and plurality of motor controllers, and each comprising memory storing configuration data of a respective one of the VDTs, each CCA configured to:
- provide the configuration data of the respective VDT to the motor controller associated with the VDT to calibrate the motor controller for use of the VDT;
- and
- interconnect a signaling line of the VDT to a signaling line of the motor controller, the interconnection providing a communication link between the VDT and the motor controller.
A method of configuring a motor controller, comprising:
- interconnecting a signaling line of a variable differential transformer (VDT) to a signaling line of a motor controller through a removable circuit card assembly (CCA) that is separate from the VDT and motor controller, wherein the VDT is configured to measure displacement of a motor, and the motor controller is configured to control the motor based on displacement data from the VDT, and wherein the interconnection provides a communication link between the VDT and the motor controller;
- and
- transmitting predefined configuration data of the VDT from memory of the CCA to the motor controller to calibrate the motor controller for use of the VDT.
