One-Touch Tuning Procedure - Mitsubishi Electric MR-J5 User Manual

One-touch tuning procedure

• 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.
