Precautions
• This parameter changes to 0 when the ZRET (Zero Point Return) motion command is exe-
cuted.
• The range for this parameter is 0 to (infinite-length axis reset position
Selection) in fixed parameter No. 1 is set to 1 (Infinite-length axis).
 Machine Coordinate System Latch Position (LPOS)
This parameter reports the latch position when the latch is completed.
Register
Address
IL18 Machine Coordinate System Latch Position (LPOS)
 Position Deviation (PERR)
This parameter reports the following deviation (internal Servo reference position − feedback
position, converted to reference units) managed by the SVC Function Module.
Register
Address
IL1A Position Deviation (PERR)
 Target Position Increment Monitor (PDV)
This parameter reports the distribution amount for each scan.
Register
Address
IL1C Target Position Increment Monitor (PDV)
 Number of POSMAX Turns
The count stored in this parameter goes up or down each time the current position exceeds the
set value of fixed parameter No. 10 (Infinite-length Axis Reset Position).
Register
Address
IL1E Number of POSMAX Turns
Precautions
• This parameter is valid for infinite-length axes.
• This parameter is not valid for linear motors.
Machine Coordinate System
This is the basic coordinate system that is set based on the execution of the ZRET (Zero Point
Return) or ZSET (Set Zero Point) command. The MP3000 manages positions using this machine
Term
coordinate system.
Reference Monitors
 Speed Reference Output Monitor
This parameter reports the speed reference value that is currently being output. This parameter
monitors the speed that is output to the servo.
Register
Address
IL20 Speed Reference Output Monitor
Precautions
This parameter is 0 for interpolation or phase control.
