j+0 Position Data (Signed 32-bit, lower 16 bits)
j+1 Position Data (Signed 32-bit, upper 16 bits)
Example 1: Position data 12345 (00003039 Hex)

j+0 3
j+1 0
When "Units (P5AA01)" of Axis-machine parameters is "0: mm" and "Position
command decimal point position (P5AA02)" is "3: 0.001", the position data
12345 is handled as 12.345mm.
Example 2: Position data − 12345 (FFFFCFC7 Hex)
15 12 11
j+0 C
j+1 F
When "Units (P5AA01)" of Axis-machine parameters is "1: inch" and "Position
command decimal point position (P5AA02)" is "2: 0.01", the position data -
12345 is handled as − 123.45inch.
Indirect specification can be used only for position data.
1. Add the symbol @ in front of position data. The stored data at the address
specified with the position data with @ is the address of the stored data to
be used.
• As shown below, @PL0001 specifies the stored data 0012 of the position
data PL0100.
Address
@PL0000
@PL0001
@PL0002
@PL00FF PL00FF
@PL0100
@PL0101
2. Indirect specification can be also used as an operand of a command.
MOVE_[J1] @PL0100 (= MOVE_[J1]#PL0012)
3. Indirect specification can be used only for reading, not for writing.
