Adjustment Procedure By Auto Tuning Mode 1 - Mitsubishi Electric MR-J5 User Manual

Adjustment procedure by auto tuning mode 1

The adjustment procedure is as follows.
• When the MR-J5_-_G_ or MR-J5-_A_ with firmware version C4 or later is used, it is recommended to set
[Pr. PA24.5 Load to motor inertia ratio/load to motor mass ratio estimation higher precision selection] to "1".
When [Pr. PA24.5] is set to "0", [Pr. PB06 Load to motor inertia ratio/load to motor mass ratio] may be
estimated at a value smaller than the accurate estimation depending on the operation pattern. Setting [Pr.
PA24.5] to "1" with the equipment on which the gain is adjusted may change the actual movement. Check
the movement of the equipment after changing the settings.

Are auto tuning
conditions satisfied?
(If the conditions are not satisfied,
it is difficult to estimate
the load to motor
inertia ratio)
Not satisfied
Set [Pr. PA08.0 Gain adjustment mode
