Abstract:
A communication module mounted to a motor provides for communication between a motor controller and a motor or between the motor controller and devices mounted on or proximate to the motor. The communication module may be configured to accept signals from various different encoders and/or load devices mounted on or proximate to the motor. The communication module receives a position feedback signal from a primary encoder interface and is configured to transmit the data to the motor controller at a periodic update rate. The communication module also receives feedback signals from at least one additional device and transmits the data to the motor controller. The communication module synchronizes its periodic update rate with the motor controller such that the position feedback signal may be utilized to control operation of the motor. The additional feedback signals may be communicated at the same or differing update rates.
