(2) Control/status signals of a simple direct operation axis
Each axis is assigned four words of PLC outputs (control signals) and three words of PLC inputs
(status signals), as shown below. The target position data and current position data are indicated by
signed 32-bit hexadecimal integers that are multiples of 0.01 mm.
*1 m indicates the head address assigned to a simple direct operation axis. (m = 12 in the example
shown on the “Overall address configuration” page.)
*2 n indicates a sequential number, such as 0, 1, 2, …, assigned only to a simple direct operation
axis, counted from the first simple direct operation axis. (n = 0 to 4 in the example shown on the
“Overall address configuration” page.)
