AC Servo System
详情介绍
Overview
AC servo systems must operate at high speeds and be capable of versatile waveform output. Communication equipment also requires different handling depending on the system or region of use.
To satisfy such demands, Renesas offers an abundant lineup of microcontrollers and microprocessors ideal for inverter control such as the RZ/T1 Group, RX71M Group, RX64M Group, and more, having a comprehensive set of integrated peripheral functions such as motor control timers and high-speed A/D converter.
