Step 1: Gather the Required Information
Record System Data
Record the data that will be used to configure system parameters. This includes motor nameplate data, AC power data,
and other motor data. Use this table to record a descriptive name, and parameter values for each drive/motor
combination. You can record data for up to five drive/motor combinations.
