îš„Parameter Settings for Autotuning
The following parameters must be set before autotuning.
* 1. 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 setting 2 (non-rotating autotuning for line-to-line resistance only) is possible for V/f control or V/f control with PG.
* 3. Stable vector control will be possible when the setting is between 50% and 100%.
* 4. For an inverter motor or vector control motor, the voltage and frequency may be lower than for a general-purpose motor. Always confirm setting on the
nameplate 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
accuracy.
* 5. The setting range is valid if Heavy Duty is selected (C6-01=0, default setting). If Normal Duty 1 or 2 is selected (C6-01=1 or 2) the setting range will be
0.0 to 400.0 Hz.
