Axis Assignment

Axes are generated/initialized by setting axis settings on the axis setting window in the engineering tool. The axes set on the
axis setting window are assigned to the global label as axis variables. For the setting method, refer to Help of the engineering
tool.
Setting items
The following shows setting items according to the axis type.
: Necessary, : Unnecessary
Axis type Axis name

Real drive axis
Virtual drive axis 

Virtual linked axis
■Axis name
Set an arbitrarily axis name of the applicable axes within 127 characters.
An instance is generated as the set axis name.
■Axis No.
Axis No. is an identifier to control in the motion system.
If the same No. is set in the multiple axes, the error "Axis No. Setting Duplication Error" (error code: 1A91H) will occur.

■Axis type
Specify an axis type of the axis.

Real drive axis
Virtual drive axis
Virtual linked axis
The data type that an axis variable can take differs depending on the axis type.
For details of data types of each axis type, refer to the following.
Page 32 Axis
■Station address
Specify the station address of the target device to connect a network device as a real axis. Also, specify the axis ID for
connecting a device which can control multiple axes with one device (multiple axes device).
These settings are unnecessary to the virtual axis.
For the station address, specify the same format as "Target modification (character string starts with @)" of TARGET_REF
structure.
For details of the TARGET_REF structure, refer to the following.
Page 358 TARGET_REF structure
Slave emulate function can be used even though the station address have not been set ("") in the real axis. If slave emulate
function is not used, the error "Station Address Setting Incorrect" (error code: 1A95H) will be output and the axis will not be
ready for operation.
