5.1 Description of Parameters
This section describes parameters critical to motion functions in the MP930.
5.1.1 Parameter Classifications
Parameters are specific constants needed for MP930 module motion functions. Set these pa-
rameters to values appropriate for machine specifications as well as for applicable Servodrive
(Servomotor + Servopack) performance.
Use a CP-717 Programming Device to create and edit parameters.
Refer to 5.1.2 List of Parameters and Appendix C Parameter Lists at the end of this manual
for lists of parameters.
Parameters are classified into the following four types.
Classification Register No. Description
Fixed Parameters No registers These parameters set machine, Servomotor,
encoder, and other mechanical conditions.
They are not normally changed once they are
set, and they cannot be changed while the sys-
tem is running.
Setting Parameters OWxx00 to OWxx3F These parameters are used to provide com-
mands to the servo control section. They can be
set from a motion programs or ladder logic
programs while the system is running.
Monitor Parameters IWxx00 to IWxx3F These parameters are servo monitor data re-
ported by the servo control section. They can
serve as reference for a motion programs or
ladder logic programs.
Servo Parameters Cn-0001 to Cn-003F This are the Servopack user constants that are
set on the Motion Parameter Screen.
The following table describes the procedures used to create, edit or change parameters.
Applicable Peripheral Device Procedure
Personal Computer Programmer Edits parameters in the Definitions Folder from the Setting
Screen.
Motion Program Uses motion programs to set setting parameters (output
registers Owxx00 to Owxx3F) with substitution state-
ments.
Ladder Logic Program Stores parameters set directly from a ladder logic program.
