Terms and Definitions Term Explanation and Definition Position Control Unit The Position Control Unit controls Servo Drives. This Position Control Unit has two EtherCAT Functions: Communications for Servo Drive control and Remote I/O master function.
Communications for Servo Drive control This function performs monitoring, setting and control when G5-series Servo Drives are connected. Remote I/O master function This function updates the I/O data in the memory area allocated to the connected slave units and PLC during each I/O refresh of the PLC when compatible devices other than G5-series Servo Drives are connected. Slave unit There are various types of slave units such as Servo Drives that handle process data and I/O terminals that handle the bit signals. The slave unit receives output data sent from the master, and transmits input data to the master. Node address An address to identify the unit connected to EtherCAT.
This Position Control Unit uses the node addresses 1 to 16 for G5-series Servo Drives and node addresses 17 onwards for other slave units (e.g., remote I/O).
