 Parameter Settings for Auto-Tuning

The following parameters must be set before Auto-Tuning.

* 1. Not normally displayed. Displayed only when a Motor Switch Command is set for a multi-function digital input (one of H1-01 to H1-06 set to 16).

* 2. The default will change when the control method is changed. The V/f Control Method default is given.

* 3. For a constant-output motor, set the value at the base speed.

* 4. For an inverter motor or vector motor, the voltage and frequency may be lower than for a general-purpose motor. Always confirm setting on the name-

plate or in test reports. Also, if you know the no-load values, set the no-load voltage in T1-03 and the no-load frequency in T1-05 to obtain better accu-

racy.

* 5. Stable vector control will be possible when the setting is between 75% and 100% of MxC rating.

* 6. The digital operator shows rpm instead of min

-1
