J Relationship of Servopack User Constants to MP930 Parameters
Some MP930 controller parameters and Servo Amp user constants have the same function. Set
these parameters carefully.
List of Parameters Requiring Special Attention
The following table shows parameters with the same function.

Parameters Motion Programs Can Write
The following Servopack user constants can be written from a motion program. (Servopack
user constants are simultaneously written whenever setting parameters are written from a mo-
tion program).
