( 1 ) Overview
( 2 ) Conditions to Enable the Simple Absolute Infinite Axis Position Control
The Zero Point Return (Setting) Completed bit (IB
the MP2300 is turned OFF and ON, the communication are interrupted by turning OFF and ON the
power supply to the SERVOPACK after the zero point has been set. The Zero Point Return (Setting)
Completed bit must therefore be turned ON when the power supply is restored.
Use the following procedure.
1.
Turn ON the power supply to the MP2300 (or clear alarms to restart communication).
The offset saved in the M register is stored to OL
2.
Check to see if communication has been synchronized.
Check to see if the Motion Controller Operation Ready bit (SVCRDY) (IB
3.
Execute the Zero Point Setting (ZSET) motion command by setting OW
Use this procedure only to turn ON the Zero Point Return (Setting) Completed bit
(IB 0C5). It cannot be used to set the Zero point of the Machine Coordinate System

Infinite length axis positioning is a function that automatically resets the machine position, program
position (absolute values in the program coordinate system), and current position at regular intervals
according to the Maximum Value of Rotary Counter (POSMAX) (fixed parameter 10). This function
can be used for repeated positioning in one direction.
The Simple Absolute Infinite Length Position Control is a position control method that can be used
for infinite length axes and has the following features.
• The coordinate system can be created simply by setting the machine coordinate system zero point
position offset when the power is turned ON (when the communication is restarted).
• No ladder program for position control is required.
For the system that satisfies the conditions to enable the Simple Absolute Infinite Length Position
Control (described in the following section), select the Simple Absolute Infinite Length Position
Control.
Set the Max. Revolution of Absolute Encoder (fixed parameter 38) to a value that satisfies the fol-
