Intelligence is Simplicity
Sensor Groups
Each feedback type is offered for all the SimplIQ drive series The drive informs the feedback type by WS[30] command and also by letter on the part number sticker:
Speed and position accuracies
Supplies and references
Emulated encoder signal
High performance, high accuracy and resolution
Ease-of-use and user friendly interface
Absolute position sensors (multi-turn and single-turn) Heidenhain serial data interface format (EnDat2.1) with sine/cosine incremental signals Stegmann HiperFace serial data interface format with sine/cosine incremental signals SSI serial data interface format (like Tamagawa style)- on development
