10.5.8 Reading actual current value
The monitor data includes D0 to D159 stored in the actual current value storage register
(shown below). Consequently, a read program does not need to be created.

Example SFC program and sequence program used to output the actual current
value of axis 1 and axis 2 to the digital display unit (controlled by Q-PLC
CPU) in [mm] units
(1) SFC program
SFC program No. 70
Reading of actual current value
The current value (D2) [0.1µm]
of axis 1 is converted into a mm
unit value to stabilize the 1st
digit display.
The current value [mm] is stored
in D6004 set by automatic refresh.
The current value (D22) [0.1µm]
of axis 2 is converted into a mm
unit value to stabilize the 1st
digit display.
The current value [mm] is stored
in D6006 set by automatic refresh.

D3, D2 : Axis 1 actual current value storage register
D23, D22 : Axis 2 actual current value storage register
D6004, D6005 : Axis 1 actual current value (Automatic refresh setting device)
D6006, D6007 : Axis 2 actual current value (Automatic refresh setting device)
REFERENCE
Since the actual current value is stored as a 32-bit data in [0.1µm] unit, it is divided
by 10,000 to convert into a [mm] unit.
