Abstract: A safety rated robotic motor control system may be configured to receive sensor data from sensors positioned on a motor. The data can be received by a programmable logic device and processed to generate a fault message based on a first set of characteristics. The fault message and the data can be transmitted to a safety controller that determines a second set of characteristics and generates operating instructions based on the fault message and the second set of characteristics.

Abstract: A motor controller configured to control different types of electronically commutated motors (ECMs) includes a range of different rotor orientation signal inputs to accommodate differences between ECM motor types. The motor controller includes a control unit that receives motor operation commands and controls operation of the ECM in accordance with the motor operation commands. The control unit receives and stores data designating ECM type and estimates rotor position based on the designated ECM type.
