Note: The Occupied Area stands for the area occupied by means of the setting of the number of remote device
stations.
The System Area stands for the system area of the remote device station.
These areas are not used for any other purpose. Also take care about duplicating the use of the data register.
(2) I/O Signal Allocation for each Axis
The I/O signal for each axis consists of 1 word for each I/O bit register.
The I/O signal for each axis consists of 4 words for each I/O data register.
z
The channel to be controlled with the port number is to be controlled by the ON/OFF signals in bit unit.
z
The current position is expressed using 2-word (32 bits) binary data (Unit: 0.01mm).
z
The force feedback data is expressed using 2-word (32 bits) binary data (Unit: 0.01N).
PLC Output (* “n” shows the head register address per each axis).
