1. Details of parameter
[Class 0] Basic setting
Title
Pr0.04
Range
Set 1st inertia ratio.
You can set up the ratio of the load inertia against the rotor (of the motor) inertia.
Pr0.04 = (load inertia/ rotor inertia) × 100 [%]
The inertia ratio will be estimated at all time while the real-time auto-gain tuning is valid, and
its result will be saved to EEPROM every 30 min.
Caution
If the inertia ratio is correctly set, the setup unit of Pr1.01 and Pr1.06 becomes (Hz). When
the inertia ratio of Pr0.04 is larger than the actual, the setup unit of the velocity loop gain
becomes larger, and when the inertia ratio of Pr0.04 is smaller than the actual, the setup unit
of the velocity loop gain becomes smaller.

You can select either the photo-coupler input or the exclusive input for line driver as the
command pulse input.

• Parameters which default values have a suffix of " * " will be automatically set up during
Note
real time auto-gain tuning. When you change manually, invalidate the real-time auto-gain
tuning first then set, referring to P.5-8, "Release of Automatic Gain Adjusting Function" of
Adjustment.
