Load inertia ratio (basic para. 32)
Basic parameter 32
Para. Name Setting range Initial value Change
32 Load inertia ratio 0.0 to 100.0 times (in 0.1 step) 0.0 Always
When the auto (low stiffness) or auto (high stiffness) is selected in tuning method (basic para. 31), the load inertia is assumed and the
parameters described before can be automatically adjusted.
The load inertia that the amplifier recognizes does not affect the basic para. 32 setting.
The load inertia can be monitored in the monitor mode [
] by the keypad panel.
If the load inertia ratio (basic para. 32) setting is 0.0, the assumed load inertia value is applied to the actual servo system. In this case, the
assumed load inertia value changes always.
If the setting value is other than 0.0, the control is made assuming that the load inertia ratio has been set. (If the setting value is 3.0, control
is made assuming that the load inertia is 3.0 times of the servo motor moment of inertia.
Remark: If the basic para. 31 setting is “0: Manual”, the gain of control system is determined as the load inertia of the load inertia ratio (basic
para.32)
If the setting is 0.0, the load assumption is not made, and the gain is set assuming that no load is applied.
