　　概述

　　伺服驱动器是将380v或220v、50Hz工频交流电整流、滤波后得到一个较平滑的直流电，经过刹车制动单元，再由IGBT或MOSFET组成的逆变电路将该直流电逆变为15～100kHz的交流电接入电机系统。应用于该10kW伺服驱动器的功率转换单元，搭配高性能电机控制MCU和驱动，通过对电压、电流信号的回馈进行处理，实现整机闭环控制，采用脉宽调制PWM控制技术获得良好的电机调速效果。

【RZ/T1】

Realize Real-Time Control of Industrial Equipment and Networking at the Same Time

The RZ/T1 Group has the Arm® Cortex®-R4 Processor with FPU core, which was designed for real-time processing, and is capable of high-speed operation at up to 600 MHz. Furthermore, access does not need to be performed via cache memory, and tightly-coupled memory capable of definitive real-time response processing is built-in, enabling high-speed access from the CPU without passing through the cache memory.

RZ/T1 devices that are equipped with a built-in R-IN engine, an accelerator for industrial Ethernet communications, can perform industrial Ethernet processing without loss of real-time performance by Hardware RTOS (HW-RTOS)

RZ/T1 devices that are equipped with a configurable absolute encoder interface are perfectly suited for precision motion control applications. The range of industry standards that are supported by the configurable encoder interface includes EnDat2.2, BiSS®-C, A-format™, Tamagawa and HIPERFACE® DSL.
