(3) Detailed Descriptions
(a) Encoder Selection
• MP2100/MP2100M fixed parameter 30
• SERVOPACK parameter Cn-0001, bit E or Pn002.2
For an axis performing absolute position detection, set MP2100/MP2100M fixed parameter 30 and
SERVOPACK parameter Cn-0001, bit E, or parameter Pn002.2 as shown in the following table.
Both the MP2100/MP2100M and SERVOPACK parameters are valid, so be sure to set both of them.
If the above settings are not used, correct motion control will not be performed. Set the parameters carefully.
