SYSTEM AND METHOD FOR ENCODER FAILURE DETECTION |
摘要 |
An encoder failure detector system and method for detecting failure of an encoder during time periods when a zero rotational speed is expected. For example, in one embodiment a test signal is applied during a period when a zero rotational speed is expected and a failure is indicated if no movement of a rotor is detected in response to the test signal.
