Industrial drives (like servo drives), require accurate, highly reliable, and low-latency position feedback. The tformat encoder interface from Tamagawa is a digital, bidirectional interface standard for position or rotary encoders. The interface transmits position values or additional physical quantities. It also allows reading and writing of the encoder’s internal memory. The type of data transmitted like absolute position, turns, temperature, parameters, diagnostics, and so on is selected through mode commands that the subsequent electronics sends to the encoder. The interface is a pure serial digital interface based on RS-485 standard.
