4.4 SVA-01 Module Parameter Details
4-95
IL††16
Machine Coordinate Feedback Position (APOS)
Range Unit
−2 31 to 2 31 −1 Reference unit
Stores the feedback position in the machine coordinate system managed by the Motion Module.
• This parameter will be set to 0 when a Zero Point Return (ZRET) is executed.
（ Note） When an infinite length axis type is selected, the position ranges from 0 to (Infinite Length Axis
Reset Position − 1).
IL††18
Machine Coordinate Latch Position (LPOS)
Range Unit
−2 31 to 2 31 −1 Reference unit
Stores the latch position when the latch has been completed.
IL††1A
Position Error (PERR)
Range Unit
−2 31 to 2 31 −1 Reference unit
Stores the following error (Machine Coordinate System Position (IL††12) − Machine Coordinate Feedback Position
(IL††16)) managed by the Motion Module.
IL††1C
Reference Position Increment Monitor
Range Unit
−2 31 to 2 31 −1 Reference unit
Stores the pulse distribution amount calculated every 500 µs cycle.
IW††1E
POSMAX Number of Turns
Range Unit
−2 31 to 2 31 −1 Rev
This parameter is valid for an infinite length axis.
The count stored in this parameter goes up and down every time the current position exceeds the Maximum Value of Rotary
Counter (POSMAX) (fixed parameter 10).
