For manufacturer setting
Set the feed forward gain.
When the setting is 100%, the droop pulses during operation at constant speed will be almost 0. When the
super trace control is enabled, constant speed and uniform acceleration/deceleration droop pulses will be
almost 0. However, sudden acceleration/deceleration will increase the overshoot. As a guideline, when the
feed forward gain setting is 100%, set 1 s or more for the acceleration time constant to the rated speed.
Setting range: 0 to 100
Set a load to motor inertia ratio or load to motor mass ratio.
Setting a value considerably different from the actual load moment of inertia or load mass may cause an
unexpected operation such as an overshoot.
The setting of this parameter will be automatic or manual depending on the setting of [Pr. PA08]. Refer to the
following table for details. When the parameter is set to automatic, the value will vary between 0.00 and
100.00.
Setting range: 0.00 to 300.00
