2.4.1 Function Enabling Conditions

 When enabling device assignment
Set the device numbers (1 to 32) to assign to each axis of the parameter "#1603 PLCdev_no". Even when the assignment is
not changed as the 1st to 3rd axes in the table below, the setting is required for all valid axes.
[Setting parameter of device assignment function]
Axis number 1
#1603 PLCdev_no 1
 When disabling device assignment
Set the parameter "#1603 PLCdev_no" of all axes to an invalid value (0).

2.4.2 Random Assignment of Bit-type Device

For bit-type PLC input/output signals, random device assignment is performed as follows:
 (Example) Servo OFF (Y7A0 to Y7BF)
