3.4 Motion Parameter Details
3.4.3 Monitor Parameter Details
 Machine Coordinate System Calculated Position (CPOS)
This parameter reports the calculated position in the machine coordinate system managed by
the Motion Control Function Module.
Register
Address
IL10
Precautions
• The position data that is stored in this parameter is the target position for each scan.
• This parameter changes to 0 when the power supply is turned ON.
• The data is updated even when the machine is locked.
• When bit 0 (Axis Selection) in fixed parameter No. 1 is set to 1 (Infinite-length axis), the range
for this parameter is 0 to (infinite-length axis reset position - 1).
 Machine Coordinate System Reference Position (MPOS)
This parameter reports the reference position in the machine coordinate system managed by
the Motion Control Function Module.
Register
Address
IL12
Precautions
• This parameter changes to 0 when the power supply is turned ON.
• This data is not updated when the machine is locked. (When the machine is locked, the posi-
tion reference data is not output externally.)
• When the machine is not locked, this parameter has the same value as the IL10 moni-
tor parameter (Machine Coordinate System Calculated Position (CPOS)).
 32-bit DPOS (DPOS)
This parameter reports the reference position in the machine coordinate system managed by
the Motion Control Function Module.
Register
Address
IL14
Precautions
• When bit 0 (Axis Selection) in fixed parameter No. 1 is set to 0 (Finite-length axis), this param-
eter has the same value as the IL10 monitor parameter (Machine Coordinate System
Calculated Position (CPOS)).
• The value of this parameter is in the range of -2
(Axis Selection) in fixed parameter No. 1.
 Machine Coordinate System Feedback Position (APOS)
SVC
This parameter reports the feedback position in the machine coordinate system managed by
the Motion Control Function Module.
