Renesas supports HIPERFACE DSL digital encoder interface with RZ/T1 solution

Renesas Electronics announced a new solution package for its RZ/T1 Group of microprocessors supporting HIPERFACE DSL digital encoder interface for AC servo applications. The support of HIPERFACE DSL for RZ/T1 reduces the customer’s system bill-of-materials cost and enables faster time-to-market.

The RZ/T1 Group includes the Arm Cortex-R4 processor with a dual precision floating-point unit (FPU) operating at up to 600 megahertz (MHz), and provides: real-time processing, tightly-coupled memory, high-speed analog to support dual servo motors, and network connectivity for distributed motion that matches the needs of precise AC servo drive applications.

The RZ/T1 already supports other leading encoder interfaces including EnDat 2.2, BiSS-C, Tamagawa and A-format. This time, the RZ/T1 newly supports the HIPERFACE DSL digital encoder interface. These digital, bidirectional interfaces provide precise position values from absolute encoders. Instead of using a separate FPGA or ASIC, integrating these encoder interfaces on the RZ/T1 reduces the component count and cuts system costs. With this expanded functionality, the RZ/T1 now supports most of the leading encoder interfaces, and with its unique configurable encoder interface, it simplifies swapping different encoders interfaces from a single device platform. 

The HIPERFACE DSL interface provided by SICK STEGMANN uses the familiar RS485 cabling with a transmission rate of 9.375 mega baud rate. The data is transmitted in synchronization with the drive cycle, and the cable between the drive electronic and feedback system can be up to 100 meters in length.
