9.2 Setting Procedure of Absolute Position Detection Function

9.2.1 System Startup Flowchart

Check Devices
1
Check to see if the SERVOPACK, Servomotor, and cables are the right products and models for the absolute encoder.
Initialize the Absolute Encoder
2
Follow the setup procedure to set the absolute encoder to default values.

Setting Parameters Related to the MP2300 and the SERVOPACKs
Set all parameters related to the Absolute Position Detection Function of the MP2300 and SERVOPACKs.

This section explains the procedure for setting the Absolute Position Detection Function.
Start up the system using the following procedure.

* If the system does not satisfy the conditions described in 9.4.1 ( 2 ) Conditions to Enable the Simple
Absolute Infinite Axis Position Control on page 9-13 when using the axis as an infinite length axis,
the MP2300 carries out the operation without using simple absolute length position control.
After the steps 2 to 4 described above are successfully completed, the absolute position detection
system will be ready for operation.
Always perform the startup procedure of the absolute position detection system in the following
situations.
・When starting up the absolute position detection system for the first time
・When the Servomotor is changed
・When an absolute encoder-related alarm occurs
