7.2.2 Setting Related Parameters
This section explains absolute position detection parameters in the MP2200/MP2300 parameters.
Set the following MP2200/MP2300 parameters and SERVOPACK parameters prior to startup the
absolute position detection system.
( 1 ) MP2200/MP2300 Parameters
( 2 ) SERVOPACK Parameters
• The parameters for which IMPORTANT precautions are provided must be set. If they are not set correctly,
the current position after turning ON the power supply may not be correct.
Machine damage may occur. Set these parameters carefully.
