An increase in the value can make the operational efficiency better. However, if the load inertia is small, it may be
necessary to adjust the value to prevent machine vibration.
Note:
• If low inertia causes vibration in the machine, decrease the setting value in 1.0-degree increments and check the response.
• To make the motor more efficient, increase the setting value in 1.0-degreee increments until the point immediately before machine
vibration starts to occur.

When you decrease the value of C5-01 [ASR Proportional Gain 1], also decrease the value of b8-21 to keep the
correct ratio.
