precision works better Description The ABG-encoder is an optical absolute encoder system. It’s a reflective kit encoder that can be fixed quickly and easily on different kinds of linear code strips and on different mounting situations. The encoder is developed for absolute positioning and linear speed control. There are different sizes of code strips are possible. Absolute encoder Absolute interface: BiSS/SSI/SPI Absolute resolution 0.8µm Power supply: 5 VDC Small size: 40.0 mm x 17.0 mm x 5.5mm Operating temperature: -25°C to +85°C Compliant EU-directive 2011/65/EU (RoHS) Various code...

It is appropriately for short cable length OPCODE Code Description 0xA6 Position Read 0x97 Register Read 0xAD Read Register Status/Data OPCODE Table Table: OPCODE Figure: SPI transmission, READ SENSOR DATA The Data is sent in packages of 8 Bits and with the MSB first. Each data transmission starts with the master sending an opcode to the slave. Reading Sensor Data: The ABG-encoder latches the absolute position on the first rising edge at SCLK, when NCS...
