10.2.2 Setting Related Parameters
This section explains absolute position detection parameters in the MP2100/MP2100M parameters.
Set the following MP2100/MP2100M parameters and SERVOPACK parameters prior to startup the absolute
position detection system.
(1) MP2100/MP2100M 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.
