* 1. Not normally displayed. Displayed only when a motor switch command is set for a multi-function digital input (one of H1-01 to H1-05 set to 16).
* 2. Only a setting of 2 (stationary autotuning for line-to-line resistance only) is possible for V/f control or V/f control with PG.
* 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 50% and 100%.
* 6. The setting range depends on the Inverter capacity and the setting of C6-01 (CT/VT Selection).
