A rotary encoder includes a stator, a malfunction determination device, and a shaft having a bearing configuration internally connected to an axial bushing arranged in a housing. The bearing configuration provides for rotation of the shaft relative to the housing. A rotor is attached to the shaft. The malfunction determination device includes a detection device configured to determine whether a connection device is operably connected between a fixed portion of the encoder and the bushing, and to output the status of the connection to a control device. If there is no connection, the detection device determines a rotation of the bushing associated with a malfunction of the bearing configuration.
A rotary encoder, comprising:
A method for determining a malfunction of a bearing configuration of a rotary encoder, the rotary encoder including a shaft having the bearing configuration, the bearing configuration being internally connected to an axial bushing arranged in a housing, the shaft being rotatable relative to the housing via the bearing configuration, a rotor being attached to the shaft, the rotary encoder including a stator, a detection device, and a connection device, the detection device adapted to determine whether the connection device is operably connected between a fixed portion of the rotary encoder and the bushing and to output a status of the connection to a control device via a communication link, comprising:
A non-volatile, computer-readable storage medium having stored there instructions, which, when executed by a processor causes the processor to perform a method for determining a malfunction of a bearing configuration of a rotary encoder, the rotary encoder including a shaft having the bearing configuration, the bearing configuration being internally connected to an axial bushing arranged in a housing, the shaft being rotatable relative to the housing via the bearing configuration, a rotor being attached to the shaft, the rotary encoder including a stator, a detection device, and a connection device, the detection device adapted to determine whether the connection device is operably connected between a fixed portion of the rotary encoder and the bushing and to output a status of the connection to a control device via a communication link, the method including:
