10.2 Starting the Absolute Position Detection Function
This section describes the procedure that is used to start the Absolute Position Detection Func-
tion.
10.2.1 System Startup Procedure
The system must be started up using the following procedure.
If steps 1 to 4 are not successfully completed, the absolute position detection function will
not operate normally.
Perform the absolute position detection system startup procedure 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

Connect the Devices
Set the MP920 and
SERVOPACK Parameters
Initialize the Absolute Encoder
Set the Zero Point
Check to see if the SERVOPACK, Servomotor,
and cables are the right products and
models for the absolute encoder.
Set the absolute position detection function
related parameters of MP920 and
SERVOPACK.
Set the absolute encoder to its default
value.
Set the zero point:
The absolute zero point, that is,
the machine coordinate system zero
point.
