2. 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).

3. Remarks
