(Description continued)
If the ratio of the overall system inertia (Sum of motor inertia and load inertia) to the motor
inertia is set in [Inertia Ratio (P2-22)], or if the value set by using the autotuning [Autotuning
(P2-24)] provided with the servo is the same as the following, the recommended set values
of [SC Loop Gain (P2-03)] by servo capacity are as follows.

(Caution !!)
However, the recommended SC Loop Gain (P2-03) set values may be deviated
according to the status of the load.
If the

80 or
□
130 motor is controlled by servo FDA-5004, use SC Loop Gain
(P2-03) of FDA-5005.

Reducing the speed integrating time constant can improve the transient response
characteristics of speed control and normal status characteristics. However, if the time
constant is reduced excessively, overshoot may occur. Select appropriate value. If 10,000 is
input, the speed integrating time constant is considered indefinite, and the speed control
turns to P control form.
