User Parameters
This section describes the Servo Driver internal user parameters. Even if operating
using the Servo Driver’s front panel switch settings, be sure to understand the kinds of
functions that are set with the parameters.
Note R7A-PR02A Parameter Unit is required to change user parameters. Refer to Operation Manual
(I534) for detailed operation procedures.
4-6-1 Parameter Tables
• The parameters for which each digit number must be set separately are given with the digit number
added to the parameter number. For example, Pn001.0 (i.e., digit 0 of parameter Pn001).
• The default setting for parameters set using 5 digits are given in the table without leading zeros
(e.g., if the default setting is 00080, 80 is given in the table).
