11.3.1 Setting User Constants
■ Position Loop Gain (Cn-001A)
Position loop gain is ideally determined by the specifications of the equipment, but initially
set a level lower than the desired value. (The factory setting is 40 (1/s).)
■ Load Inertia (Cn-0003)
Set the load inertia for the moment of inertia ratio on motor shaft. (This constant is factory set
to 100 (%), which is equivalent to the motor inertia.)
