Speed control gain adjustment

• The load inertia ratio (load moment of inertia) for the motor is calculated from the torque command and rotation speed
during motor driving under Vector control. Because the optimum gain for speed control using dancer feedback / tension
sensor feedback is calculated automatically from the load inertia ratio and the response level, the work required for gain
adjustment is reduced (easy gain tuning).
• The load inertia ratio can be entered manually if you already know the ratio.
• Manual gain adjustment is useful for achieving optimum machine performance or improving unfavorable conditions, such
as vibration and acoustic noise during operation with high load inertia.
