6 Basic Parameter Settings

High-function General-purpose Inverter RX2 Series User’s Manual
Note The above table shows the case where [SET] terminal is OFF or not selected. If [SET] terminal is made ON
and the secondary setting is used, the parameters of [H*21*] ([Hb210], [Hd210], etc.) are effective and
overwritten according to the selection of the control type [AA221].
1 Check the control type [AA121].
For the induction motor (IM), make sure that the control type [AA121] is set to the one for IM.
For the synchronous motor (SM) or permanent magnetic motor (PMM), make sure that the con-
trol type [AA121] is set to the one for PMM.
2 Set the auto-tuning selection [HA-01].
In the auto-tuning selection [HA-01], 01: Non-revolving or 02: Revolving is set. The tuning does
not begin at this stage. Only “non-revolving” can be chosen for synchronous motor (SM) / per-
manent magnetic motor (PMM).
3 Set a start command for tuning.
Pressing OPERATION button on the LCD operator starts the tuning, Pressing STOP button ter-
minates the tuning, However tuning data are not saved.
4 The inverter automatically operates.
Output of a preset pattern is given to the motor. If the auto-tuning selection [HA-01] is set to 01:
Non-revolving, non-revolving output of three different patterns is given.
If the auto-tuning selection [HA-01] is set to 02: Revolving, acceleration and deceleration are
repeated twice in addition to the above output. The frequency increases up to 80% of the base
frequency.
After the above operation finishes, the output with no revolution is checked as final check.
5 The tuning finished.
When the tuning End display appears, the tuning finishes. Use STOP key to cancel the End dis-
play.
